Precautions

Samsung Electronics 1-1

1. Precautions

Follow these safety, ESD, and servicing precautions to prevent personal injury and equipment damage.

1-1 Safety Precautions

1. Be sure that all built-in protective devices are in

place. Replace any missing protective shields.

2. Make sure there are no cabinet openings

through which people-particularly children- might

insert ﬁngers or objects and contact dangerous

voltages.

3. When re-installing chassis and assemblies be

sure to replace all protective devices including

control knobs and compartment covers.

4. Design Alteration Warning:Never alter or add to

the mechanical or electrical design of this equip-

ment, such as auxiliary connectors, etc. Such

alterations and modiﬁcations will void the manu-

facturer’s warranty.

5. Components, parts, and wiring that appear to

have overheated or are otherwise damaged

should be replaced with parts which meet the

original speciﬁcations. Always determine the

cause of damage or overheating, and correct any

potential hazards.

6. Observe the original lead routing, especially near

sharp edges, AC, and high voltage power sup-

plies. Always inspect for pinched, out-of-place,

or frayed wiring. Do not change the spacing

between components and the printed circuit

board.

7. Product Safety Notice:Some electrical and

mechanical parts have special safety-related

characteristics which might not be obvious from

visual inspection. These safety features and the

protection they provide could be lost if a replace-

ment component differs from the original. This

holds true, even though the replacement may be

rated for higher voltage, wattage, etc.

8. Components critical for safety are indicated in

the parts list with symbols .

Use only replacement components that have the

same ratings, especially for ﬂame resistance and

dielectric speciﬁcations. A replacement part that

does not have the same safety characteristics as

the original may create shock, ﬁre, or other

safety hazards.

1-2 Precautions on Disassembly and Reassembly

Take great care when replacing parts. Before remov-

ing a part take careful note of its orientation and any

wiring routing. Ensure that all parts removed are cor-

rectly replaced in their original positions and all wir-

ing is routed as it was originally manufactured.

Changing wiring routes can cause electrical interfer-

ence or degradation in set performance.

Please do the following before disassembling for a

repair or replacement of parts.

1. Remove the paper cassette and toner cartridge.

Take great care to ensure that the developer

drum surface is not scratched or damaged by

exposure to light.

2. Turn the power switch off.

3. Take out the power plug and disconnect the printer

cable from the printer.

4. Use only the same type of part as originally ﬁtted

when replacing parts.

5. Take care when dismantling plastic components

and covers. Ensure covers are not damaged. Do

not force plastic components apart they may

break.

6. Be careful that small parts such as screws do not

get lost inside the printer.

7. When disassembling take note of the placement of

small parts. Ensure all small parts are properly

reassembled.

8. If is is necessary to turn the printer upside down

protect the LSU window with clean paper so that

no loose toner particles contaminate the glass.

Releasing Plastic Latches

Many of parts are held in

place with plastic latches.

The latches break easily :

release them carefully.

To remove such parts,

press the hook end of the

latch away from the part to

which it is latched.

Precautions

Samsung Electronics1-2

1-3 ESD Precautions

1. Certain semiconductor devices can be easily

damaged by static electricity. Such components

are commonly called “Electrostatically Sensitive

(ES) Devices”, or ESDs. Examples of typical

ESDs are: integrated circuits, some ﬁeld effect

transistors, and semiconductor “chip” compo-

nents.

The techniques outlined below should be fol-

lowed to help reduce the incidence of component

damage caused by static electricity.

CAUTION

: Be sure no power is applied to the chassis

or circuit, and observe all other safety pre-

cautions.

2. Immediately before handling a semiconductor

component or semiconductor-equipped assem-

bly, drain off any electrostatic charge on your

body by touching a known earth ground. Alterna-

tively, employ a commercially available wrist

strap device, which should be removed for your

personal safety reasons prior to applying power

to the unit under test.

3. After removing an electrical assembly equipped

with ESDs, place the assembly on a conductive

surface, such as aluminum or copper foil, or con-

ductive foam, to prevent electrostatic charge

buildup in the vicinity of the assembly.

4. Use only a grounded tip soldering iron to solder

or desolder ESDs.

Use only an “anti-static” solder removal device.

Some solder removal devices not classiﬁed as

“anti-static” can generate electrical charges sufﬁ-

cient to damage ESDs.

5. Do not use Freon-propelled chemicals. When

sprayed, these can generate electrical charges

sufﬁcient to damage ESDs.

6. Do not remove a replacement ESD from its pro-

tective packaging until immediately before install-

ing it. Most replacement ESDs are packaged

with all leads shorted together by conductive

foam, aluminum foil, or a comparable conductive

material.

7. Immediately before removing the protective

shorting material from the leads of a replace-

ment ESD, touch the protective material to the

chassis or circuit assembly into which the device

will be installed.

8. Maintain continuous electrical contact between

the ESD and the assembly into which it will be

installed, until completely plugged or soldered

into the circuit.

9. Minimize bodily motions when handling unpack-

aged replacement ESDs. Normal motions, such

as the brushing together of clothing fabric and

lifting one’s foot from a carpeted ﬂoor, can gener-

ate static electricity sufﬁcient to damage an ESD.

1-4 Super Capacitor or Lithium Battery Precautions

1. Exercise caution when replacing a super capaci-

tor or Lithium battery. There could be a danger of

explosion and subsequent operator injury and/or

equipment damage if incorrectly installed.

2. Be sure to replace the battery with the same or

equivalent type recommended by the manufac-

turer.

3. Super capacitor or Lithium batteries contain toxic

substances and should not be opened, crushed,

or burned for disposal.

4. Dispose of used batteries according to the manu-

facturer’s instructions.

3-1 General Precautions on Disassembly

When you disassemble and reassemble components, you must use extreme caution.

The close proximity of cables to moving parts makes proper routing a must. If components are removed, any

cables disturbed by the procedure must be restored as close as possible to their original positions. Before

removing any component from the machine, note the cable routing that will be affected.

Whenever servicing the machine, you must carry out the following :

1. Check to verify that documents are not stored in memory.

2. Unplug the power cord.

3. Use a ﬂat and clean surface.

4. Replace only with authorized components.

5. Take care when removing plastic component-do not force.

4-4-3 SYSTEM DATA

DIALING MODE

Select the dialing mode according to the user's line status.

TONE: Electrical type of dial

PULSE: Mechanical type of dial

SILENCE TIME

In ANS/FAX mode, after a call is picked up by the answering machine, the machine monitors the line. If a

period of silence is detected on the line at any time, the call will be treated as a fax message and the machine

begins receiving.

Silence detection time is selectable between limited (about 12 seconds) and unlimited time.

When '12 sec' is selected, the machine switches to receiving mode as soon as it detects a period of silence.

When 'unlimited'is selected, the machine waits until the answering operation is concluded even though a

period of silence is detected. After the answering operation is concluded, the machine switches to receiving

mode.

SEND FAX LEVEL

You can set the level of the transmission signal. Typically, the Tx level should be under -12 dBm.

Caution: The Send Fax Level is set at the best condition in the shipment from factory. Never change

settings arbitrarily.

ERROR RATE

Tou can set the Error Rate between 5% and 10%. During operation the set monitors the rror rate.

When the rror rate approaches the preset value the machine automatically steps down the baude to 2400bps

to ensure that the selected error rate is not exceeded.

MODEM SPEED

You can set the maximum modem speed. It is better left set 33.6Kbps (the default setting ).

During call setup the baud rate is automatically adjusted to suite the slowest device. Only adjust this where

the local line conditions are extremely poor.

4-4-4 MEMORY CLEAR

CLEAR ALL MEMORY

This function resets the system to its original factory settings. All settings entered in User Mode and Tech

Mode are reset. This includes any User Phone Book entries, jobs stored in memory or received documents

that have not been printed. If possible use the Control Panel software to download customer settings and

phone book settings before carrying out a full reset.

When diagnosing or testing a faulty unit this function is often useful. Be aware that all error reports are also

cleared.

< Method >

1. Select the [MEMORY CLEAR] in TECH MODE.

2. Push the ENTER button.

3. Select your country.

4. Push the ENTER button and all memory will be cleared.

NOTICE : Always perform a memory clear after replacing the main board or updating the ﬁrmware. Oth-

erwise, the system may not operate properly.

CLEAN DRUM

Use this feature to remove toner particles remaining in the OPC drum unit.

Use this feature when print quality falls or when marks or specks appear on the printout.

You should perform this feature several times until a clean printout appears.

The machine automatically pulls in a sheet of paper and prints out. Excess toner particles on the OPC drum

surface are ﬁxed to the paper.

FLASH UPGRADE

This function is used to update the system Firmware. There are 2 methods Local and Remote.

More information can be found in the ﬁrmware upgrade section.

ADJUST SHADING

This option is used to test and check the functionality of the CCD (Charge Coupled Device). Use this when

poor quality scanning or copying is reported.

< Method >

1. Select the [ADJUST SHADING] in TECH MODE.

2. Push the SET UP button. The unit scans

a “white image” using the ‘white bar’

3. After the scan, CCD SHADING PROFILE similar to that

shown will be printed out.

4. If the printed image is different to the image, if the lines

are signiﬁcantly lower or higher, or if there are high or low

spots in the chart then the CCD is defective.

NOTICE : When you test the CCD, make

sure that the cover is closed.”

ANSWER ON CNG

The function is to control the CNG TONE recognition times for entering receiving mode from the AUTO MODE

or ANS/FAX MODE.

LSU window, then the developer is nor-

mal.

(Because of foreign substance on the

LSU window, the image has not been

printed partly.)

3. In case of 3-

If the cycle of noise is about 2 seconds,

the toner inside the developer has been

nearly exhausted.( Purchase and replace

with a new developer after using about

200 sheets at the point of occurrence)

4. In case of 3-

This is a phenomenon caused by lack of

toner, so replace with a new developer.

Toner Contamina-

tion • Toner is fallen on the

papers periodically.

• Contaminated with

toner on prints

partly or over the

whole surface.

1. Toner is fallen on the paper peri-

odically.

(1)Check the cycle of the falling of

the toner.

(2)Check the appearance of both

ends of the developer OPC

drum.

2.The center of the printed matter is

contaminated with toner.

(1)Check whether foreign sub-

stances or toner are stuck to the

terminal (contact point) of the

developer.

(2)Check whether the state of the

terminal assembly is normal.

1. If both ends of the OPC drum are con-

taminated with toner:

Check the life of the developer.

2. Check whether it could be recycled.

White Black spot • Light or dark black

dots on the image

occur periodically.

• White spots occur in

the image periodi-

cally.

1. If light or dark periodical black

dots occur, this is because the

developer rollers are contami-

nated with foreign substance or

paper particles.

(1)37.7mm interval :

Charged roller

(2)94.3mm interval :

OPC cycle

2. If white spots occur in a black

image at intervals of 94.3 mm, or

black spots occur elsewhere, the

OPC drum is damaged or foreign

substance is stuck to the surface.

3. If a black and white or graphic

image is partially broken at irregu-

lar intervals, the transfer roller's

life has been expired or the trans-

fer voltage is abnormal.

1. In case of 1 above -

Run OPC Cleaning Mode Print 4-5 times

repeatedly to remove. Especially check

foreign substance on the OPC surface,

then remove them with a clean gauze

moistened with IPA(Isopropyl Alcohol) not

to damage OPC if necessary.

Caution : Never use usual alcohol.

2. In case of 2

If they are not disappeared by running

OPC Cleaning Mode Print 4-5 times.

: at intervals of 94.3mm -

Replace the OPC Drum.

: at intervals of 37.7mm -

Remove foreign substance, Clean the

Charged Roller

: Broken image -

Replace the developer according to

carelessness.

3. In case of 3 - Exchange the transfer

roller because the life of the transfer roller

in use has been expired. (Check the

transfer voltage and readjust if different.)

Recycled product • Poor appearance of

the developer.

• Unclean and rough

printouts.

• Bad background in

the image.

1. Poor appearance of the devel-

oper.

(1)Check the damage to label and

whether different materials are

used.

(2)Check the appearance of parts

of the developer, such as frame,

hopper.

2. Unclean and rough printouts.

(1)Check whether foreign sub-

stance or toner are stuck to the

terminal (contact point) of the

developer.

(2)Check whether the state of the

terminal assembly is normal.

1. In case of 1 -

(1)If there is an evidence of disassembling

the developer.

(2)If materials other than normal parts of

the developer are added or substituted.

2. In case of 2 - If there are any abnormals

in connection with the situation of 1.

(1)It occurs when the developer is recy-

cled over 2 times.

(2)If toner nearly being expired are col-

lected to use, it is judged as the recycled

developer.

Ghost & Image

Contamination • The printed image is

too light or dark, or

partially contami-

nated black.

• Totally contaminat-

edblack.

(Black image

printed out)

1. The printed image is too light or

dark, or partially contaminated

black.

(1)Check whether foreign sub

stance or toner are stuck to the

terminal(point of contact) of

the developer.

(2)Check whether the terminal

assembly is normal.

2. Totally contaminated black.

(Black image printed out)

(1)Check whether foreign sub

stances are stuck to the termi-

nal(point of contact) of the

developer and the state of

assembly.

(Especially check the charged

roller terminal.)

1. All of 1, 2, 3 above

(1)Remove toner and foreign substances

adhered to the contact point of the

developer.

(2)The contact point of the unit facing that

of the developer also must be cleaned.

(3)If the terminal assembly is unsafe:

• Fully stick the terminal to or reassemble

it after disassembling.

• Disassemble the side plate and push

the terminal to be stuck, then reassem-

ble it.

2. In case of 2

It is a phenomenon when the OPC drum

of the developer is not electrically

charged. Clean the terminals of the

charged roller, then recheck it.

Samsung Electronics 4-45

4-6-6 The cause and solutions of bad environment of the software

4-6-6-1 The printer is not working (1)

4-6-6-2 The printer is not working (2)

Check and Cause Solution

1. Check if the PC and the printer is properly connected and

the toner cartridge installed.

2. Printing is nor working in the Windows.

3. Check if the printer cable is directly connected to peripheral

devices

1. Replace the printer cable. If the problems not solved even

after the cable replaced, check the amount of the remaining

tone.

2. Check if the connection between PC and printer port is

proper. If you use windows, check if the printer driver in the

controller is set up. If the printer driver is properly set up,

check in which program the printing is not working. The best

way to ﬁnd out is to open the memo pad to check the func-

tion of printing. If it is not working in a certain program, adjust

the setup the program requires. Sometimes, the printout is

normal within the Windows basic programs, but it's not work-

ing in a particular program. In such case, install the new

driver again. If not working in the Windows basic program,

Check the setup of the port of CMOS is on ECP. And check

the address of IRQ 7 and 378

3. If the scanner needs to be connected to the printer, ﬁrst the

remove the scanner from the PC to see if the printer is prop-

erly working alone.

Check and Cause Solution

1. Secure more space of the hard disk.

2. Printing error occurs even if there is enough space in the

hard disk.

3. Check the parallel-port-related items in the CMOS Setup.

4. Reboot the system to print.

1. Not working with the message 'insufﬁcient printer memory'

means hard disk space problem rather than the RAM prob-

lem. In this case, provide more space for the hard disk.

Secure more space using the disk utilities program.

2. The connection of the cable and printer port is not proper.

Check if the connection is properly done and if the parallel

port in CMOS is rightly set up.

3. As a printer port, Select ECP or SPP among SPP(Normal),

ECP, and EPP modes(increase printing speed) SPP normal

mode support 8-bit data transfer, while ECP Mode transfer

the 12-bit data.

4. If the regular font is not printing, the cable or the printer

driver may be defective.

Turn the PC and printer off, and reboot the system to print

again. If not solved, double-click the printer in my computer

If the regular fonts are not printed this time again. the cable

must be defective so replace the cable with new one.

• Description : After receiving the printing order, no response at all or the low speed of printing occurs

due to wrong setup of the environment rather than malfunction of the printer itself.

• Description :

While Power turned on, the printer is not working in the printing mode.

Troubleshooting

4-6-6-3 Abnormal Printing

4-6-6-4 SPOOL Error

Check and Cause Solution

1. Set up the parallel port in the CMOS SETUP.

2. Printer Driver Error.

3. Error message from insufﬁcient memory.

(The printing job sometimes stops or due to insufﬁcient vir-

tual memory, but it actually comes from the insufﬁcient space

of the hard disk.)

1. Select SPP(Normal) or ECP LPT Port the among ECP,

EPP or SPP in the CMOS Setup.

2. Check the printer in My Computer.(to see if the printer driver

is compatible to the present driver or delete the old driver, if

defective and reinstall the new driver)

3. Delete the unnecessary ﬁles to secure enough space of the

hard disk and start printing job again.

Check and Cause Solution

1. Insufﬁcient space of the hard disk in the directory assigned

for the basic spool.

2. If the previous printing error not solved.

3. When expected to collide with other program.

4. When an application program or the printer driver is dam-

aged.

5. When some ﬁles related to OS are damaged or virus

infected.

6. Memory is less than suggested one.

1. Delete the unnecessary ﬁles to provide more space to start

printing job.

2. If there are some ﬁles with the extension name of ****.jnl,

Delete them and Reboot the Windows to restart printing job.

3. Shut down all other programs except the current one, if pos-

sible.

4. Delete the printer driver completely and reinstall it.

5 After rebooting the computer, check for viruses, restore the

damaged ﬁles and reinstall the program to do the printing

job.

6. Add up enough memory to the PC.

• Description : The printing is not working properly even when the cable has no problem.

(even after the cable is replaced) If the printer won't work at all or the strange fonts are

repeated, the printer driver may be defective or wrong setup in the CMOS Setup.

• Description : To spool which stands for "simultaneous peripheral operations online" a computer doc-

ument or task list (or "job") is to read it in and store it, usually on a hard disk or larger

storage medium so that it can be printed or otherwise processed at a more convenient

time (for example, when a printer is ﬁnished printing its current document).

How to delete the data in the spool manager.

In the spool manager, the installed drivers and the list of the documents waiting to be printed are shown.

Select the document to be deleted and check the delete menu.

If you intend to delete the current document being printed, the data being transferred to the printer will be put

out and then the document is removed. Before choosing the document, the menu is still inactive.

Or put the document out of the list and repeat the routine as in the above or ﬁnish the spool manager.

3-2-5-1 SDRAM read timing

Basically the Extended Data Out DRAM is similar to Fast Page Mode DRAM. For FPM, the data are valid only

when the nCAS is active while reading the internal data, however, it has a latch that the data will be

continuously outputted even after the nCAS is inactivated.

While conﬁguring the software, you must set the timing register of SFR considering the clock speed and the

DRAM spec.

* Note : 1. CS can be don’t cared when RAS, CAS and WE are hih at the clock high going dege.

2. To interrupt a burst read by row precharge, both the read and the precharge banks must be the

same.

3-4 HOST INTERFACE:

Referred to IEEE 1284 standard.

3-4-1. Host Interface

PARALLEL PORT INTERFACE PART ARM946ES has the Parallel Port Interface Part that enables Parallel

Interface with PC. This part is connected to PC through Centronics connector. It generates major control

signals that are used to actuate parallel communication. It is comprised of/ERROR, PE, BUSY, /ACK,

SLCT, /INIT, /SLCTIN, /AUTOFD and /STB. This part and the PC data transmission method support the

method speciﬁed in IEEE P1283 Parallel Port Standard (http://www.fapo.com/ieee1284.html). In other

words, it supports both compatibility mode (basic print data transmitting method), the nibble mode

(4bit data; supports data uploading to PC) and ECP (enhanced capabilities port: 8bits data - high speed

two-way data transmission with PC). Compatibility mode is generally referred to as the Centronics mode

and this is the protocol used by most PC to transmit data to the printer. ECP mode is an improved pro-

tocol for the communication between PC and peripherals such as printer and scanner, and it provides

high speed two-way data communication. ECP mode provides two cycles in the two-way data transmis-

sion; data cycle and command cycle. The command cycle has two formats; Run-Length Count and Chan-

nel Addressing. RLE (Run-Length Count) has high compression rate (64x) and it allows real-time data

compression that it is useful for the printer and scanner that need to transmit large raster image that has a

series of same data. Channel Addressing was designed to address multiple devices with single struc-

ture. For example, like this system, when the fax/printer/scanner have one structure, the parallel port can be

used for other purposes while the printer image is being processed.This system uses RLE for high speed

data transmission. PC control signals and data send/receive tasks such as PC data printing, high speed

uploading of scanned data to PC, upload/download of the fax data to send or receive and monitoring the sys-

tem control signal and overall system from PC are all processed through this part.

3-5 Engine Controller

3-5-1. Fuser Control / Thermistor Circuit

This circuit controls the heat lamp temperature to ﬁx the transferred toner on the paper. It is comprised of the

thermistor that has the negative resistance against the temperature and LM393 (voltage comparator) and

transistor for switching.

The thermistor has the resistance value reverse proportional to the heat lamp surface temperature. The volt-

age value is read by #60 pin(AVIN2) of CPU refering to the parallel combined resistance with the resis-

tor(R43) connected parallel to it and the voltage distribution of R29. The voltage read activates (inactivates)

‘fuser’ signal to high (or low) referring to the set temperature and when the ‘fuseron’ signal turns down(high)

to low(high) by Q3 switching, the S21ME4 inside SMPS (PC3) turns on(off) and this eventually turns two-way

thyristor(SY1) on(off) to allow(shut) AC voltage to the heat lamp.

LM393 is a H/W designed to protect the system when the software heat lamp control does not run normal.

When the thermistor temperature goes up to 210°C, #1 pin’s level (LM393) will turn low to turn the ‘fuseron’

signal to high. (forcefully shuts off Q3)In other words LM393 shuts off the heat lamp forcefully.

3-5-2. Paper Sensing Circuit

1) Cover Open Sensing

Cover Open Sensor is located on the right rear side of the printer. In case the right cover is open, it

shuts +5V (LSU laser unit) and +24V(main motor, polygon motor of ﬁxer LSU and HVPS) that are

supplied to each unit. It detects the cover opening through CPU. In this case, the red LED of the

OP Panel LED will turn on.

2) Paper Empty Sensing

The paper empty sensor (photo interruptor), located inside bottom of the bin cassette detects paper

with the actuator connected to it and informs the CPU of whether there is paper. When there is no

paper in the cassette, the red LED of the OP panel LED will turn on to tell the user to ﬁll the cassette

with papers.

3) Paper Feeding When the paper is fed into the set and passes through the actuator of the feed sensor

unit, transistor inside the photo interrupter will turn on, ‘nFEED’ signal will turn low and inform CPU that

the paper is currently fed into the system. CPU detects this signal and sprays video data after certain

time (related to paper adjustment). If the paper does not hit the feed sensor within certain time, CPU

detects this and informs as “Paper Jam0” (red LED on the OP panel will turn on).

4) Paper Exit Sensing

The system detects the paper going out of the set with the exit sensor assembled to the actuator

attached to the frame. If CPU does not turn back high a while after the paper hits the exit sensor, CPU

detects this and inform as “Paper Jam2” (red LEDs on the OP panel will turn on).

3-5-3. LSU Circuit

1) Polygon Motor Unit (actuated by +24V)

The polygon motor inside LSU rotates by the ‘PMOTOR’ signal. When it reaches the motor constant

velocity section through the initial transient (transient response) section, it sends the ‘nLREADY’ signal

to the CPU.

The ‘clock’ pin is the pin that receives clock of the required frequency when LSU uses external CLK as

the motor rotational frequency. Currently the external clock circuit is located in the HVPS and 1686Hz

= 6.9083MHz (crystal frequency)÷212(74HC4060N IC), is used as the rotational frequency of the

polygon motor.

2) Laser Unit (actuated by +5V)

After laser is turned on by ‘nLD_ON’ signal, it is reﬂected by 6 mirrors (polygon mirror) attached to

the polygon motor and performs scan in horizontal way.When the laser beam hits the corner of the

polygon mirror, it generates ‘nHSYNC’ signal (pulse) and the CPU forms the left margin of the image

using this signal (horizontal synchronous signal).

3-5-4. Fan/Solenoid Actuation Circuit

The fan actuation circuit its power using NPN TR. When it receives ‘FAN’ signal from the CPU. The TR will turn

on to make the voltage supplied to the fan to 24V in order to actuate the fan.

The solenoid is actuated in the same way. When it receives control signal from the CPU, the solenoid for

paper feeding is actuated by switching circuit.

D29(1N4003) diode is applied to the both ends of the output terminal to protect Q22(KSC1008-Y) from

noise pulse induced while the solenoid is de-energized.

3-5-5. PTL Actuation Circuit

PTL actuation circuit switches its power using NPN TR.

3-5-6. Motor Actuation Circuit

Motor actuation circuit is determined while selecting the initial driver IC (provided by the vendor). This sys-

tem uses TEA3718(U57, U58), A2918(U59)’s motor driver IC. However, the sensing resistance (R273, R274,

R292, R293) and reference resistance (R284, R289, R294, R295) can vary depending on the motor actua-

tion current value.

It receives motor enable signal (2 phase) from CPU and generates bipolar pulse (constant-current) and

sends its output to stepping motor input.

3-5-7. High Voltage Power Supply

3-5-7-1. Summary

It is the high voltage power supply that has DC+24V/DC+5V (used for the image forming device in OA dig-

ital picture developing method) as the rated inputs. It supplies electrifying voltage (MHV), supply voltage

(SUPPLY), developing voltage (DEV), blade voltage(BLADE) and transferring voltage (THV).

Each high voltage supply shows the voltage required in each digital picture process.

3-5-7-2. Digital Picture Process

Digital picture developing method is widely used by copy machine, laser beam printer and fax paper.

The process is comprised of electriﬁcation, exposure, develop, transfer and ﬁxing.

First, in the electriﬁcation process, retain constant charge at approx. -900V for the electric potential on the

OPC surface by electrifying OPC drum at approx. -1.4KV through the electriﬁcation roller.

The electriﬁed surface of OPC is exposed responding to the video data by the LSU that received print com-

mand due to rotation. The unexposed non-video section will retain the original electric potential of -900V, but

the electric potential of the image area exposed by LSU will be approx. -180V that it will form the electro-

static latent image. The surface of the photo-conductive drum where the electrostatic latent image is

formed reaches the developer as the drum rotates. Then the electrostatic latent image formed on the OPC

drum is developed by the toner supplied to the developing roller by supplying roller and it is transformed into

visible image. It is the process to change the afterimage on the OPC drum surface formed by LSU into visi-

ble image by the toner particles.

While the supply roller energized with -450V by HVPS and the developer roller energized with -300V

rotate in the same direction, it keeps the toner particles between two rollers supplied to OPC drum in nega-

tive state by the friction between two rollers.

The toner supplied to the developer roller is biased to bias electric potential by the developer roller and

transferred to the developing area. After (-) toner is attached to the developer roller, it will move to the exposed

high electric potential surface (-180V) rather than to the unexposed low electric potential surface (-900V) of

the developer roller and OPC drum. Eventually the toner will not settle in the low electric potential surface to

form the visible image.

Later, the OPC drum continues to rotate and reaches to transfer location in order to accomplish the transfer

process.

This process transfers the (-)toner on the transfer roller to the printing paper by the transfer roller. The (-

)toner attached to the OPC drum will be energized to hundreds to thousands of the (+)transfer voltage by

HVPS. The (+)electrostatic force of the transfer roller generated has higher adhesiveness than the (-)toner

OPC drum and thus it moves to the surface of the paper passing through the transfer roller.

The toner transferred to the paper with weak electrostatic force is ﬁxed to the paper by the pressure and heat

of the ﬁxer composed of pressure roller and heat roller.

The toner attached to the paper is melted by applying the heat (approx. 180°C) from the heat roller and the

pressure (approx. 4kg) from the pressure roller. After the ﬁxing process, the paper is sent out of the set to

ﬁnish the printing process.

3-5-7-4 MHV (Electriﬁcation Output Enable)

Electriﬁcation Output Enable is the electriﬁcation output control signal 'PWM-LOW ACTIVE'.

When MHV-PWM LOW signal is received, Q401 turns on and the steady voltage will be accepted to the non-

inverting terminal of OP-AMP 324. As the voltage higher than the inverting reference voltage of OP-AMP,

which is set to R405 and R406, OP-AMP output turns high. This output sends IB to the TRANS auxiliary

wire through current-restricting resistance Q402 via R408 and C403 and Q402 turns on. When the current

is accepted to Q402, Ic increases to the current proportional to time through the T401 primary coil, and when

it reaches the Hfe limit of Q402, it will not retain the "on" state, but will turn to "off". As Q402 turns 'off',

TRANS N1 will have counter-electromotive force, discharge energy to the secondary unit, sends current to

the load and outputs MHV voltage through the high voltage output enable, which is comprised of Regula-

tion– circuit.

3-5-7-5 BIAS (supply/dev/blade output unit)

BIAS (Electriﬁcation Output Enable)Electriﬁcation Output Enable is the electriﬁcation output control signal

‘PWM-LOW ACTIVE’.When BIAS-PWM LOW signal is received, Q501 turns on and the steady voltage will

be accepted to the non-inverting terminal of OP-AMP 324. As the voltage higher than the inverting reference

voltage of OP-AMP, which is set to R506 and R507, OP-AMP output turns high. This output sends IB to

the TRANS auxiliary wire through current-restricting resistance Q502 via R509 and C504 and Q502 turns

on. When the current is accepted to Q502, Ic increases to the current proportional to time through the T201

primary coil, and when it reaches the Hfe limit of Q502, it will not retain the “on” state, but will turn to “off”.

As Q502 turns ‘off’, TRANS N1 will have counter-electromotive force, discharge energy to the secondary

unit, sends current to the load and outputs DEV voltage through the high voltage output enable, which is

comprised of Regulation-circuit.

3-5-7-6. THV(THV(+)/THV(-) Output Unit)

Transfer(+) output unit is the transfer output control signal 'PWM-LOW ACTIVE'.

When THV-PWM LOW signal is received, Q203 turns on and the steady voltage will be accepted to the non-

inverting terminal of OP-AMP 324. As the voltage is higher than the inverting reference voltage of OP-AMP,

OP-AMP output turns high.

The 24V power adjusts the electric potential to ZD201 and ZD202, sends IB to TRANS auxiliary wire

through current-restricting resistance R215 via R212 and C204, and eventually Q204 will turn on. When

the current is accepted to Q402, Ic increases to the current proportional to time through the T201 primary coil,

and when it reaches the Hfe limit of Q204, it will not retain the "on" state, but will turn to "off". As Q402 turns

'off', TRANS N1 will have counter-electromotive force, discharge energy to the secondary coil, sends cur-

rent to the load and outputs THV voltage through the high voltage output enable, which is comprised of

Regulation– circuit. The output voltage is determined by the DUTY width. Q203 switches with PWM DUTY

cycle to ﬂuctuate the output by ﬂuctuating the OP-AMP non-inverting end VREF electric potential, and the

maximum is output at 0% and the minimum, at 100%.Transfer(-) output unit is THV-EA 'L' enable.

When THV-EA is 'L', Q302 turns on and the VCE electric potential of Q302 will be formed and sends IB to

TRANS auxiliary wire through R311, C305 and VR302 via current-restricting resistance R314, and eventu-

ally Q303 will turn on. When the current is accepted to Q303, Q303's Ic increases to the current proportional

to time through the T301 primary coil, and when it reaches the Hfe limit of Q303, it will not retain the "on" state,

but will turn to "off". As Q303 turns 'off', TRANS N1 will have counter-electromotive force, discharge

energy to the secondary coil, send current to load and output THV(-) voltage through the high voltage output

enable, which is comprised of Regulation– circuit.

3-5-7-7. Environment Recognition

THV voltage recognizes changes in transfer roller environment and allows the voltage suitable for the envi-

ronment in order to realize optimum image output. The analog input is converted to digital output by the

comparator that recognizes the environmental changes of the transfer roller. It is to allow the right transfer

voltage to perform appropriate environmental response considering the environment and the type of paper

depending on this digital output by the programs that can be input to the engine controller ROM.

This environment recognition setting is organized as follows: First, set the THV(+) standard voltage.

Allow 200MΩ load to transfer output, enable output and set the standard voltage 800V using VR201.

Then set 56 (CPU's recognition index value) as the standard using VR302.

This standard value with CPU makes sure that the current feedback is 4µA when output voltage is 800V and

load is 200MΩ.

If the load shows different resistance value when 800V is output, the current feedback will also be different

and thus the index value will also be different. according to the index value read by CPU, the transfer voltage

output will differ according to the preset transfer table.

The changes in transfer output required by each load is controlled by PWM-DUTY.

3-6 OPE PBA

3-6-1 SUMMARY

OPE Board is separated functionally from the main board and operated by the micom(HT48R50) in the board.

OPE and the main use UART (universal asynchronous receiver/transmitter) channel to

exchange information. OPE reset can be controlled by the main. OPE micom controls key-scanning and LCD

and LED display. If there occurs an event in OPE (such as key touch), it sends speciﬁc codes to the main to

respond to the situation and the main analyzes these codes and operates the system. For example, it the

main is to display messages in OPE, the main transmits data through UART line to OPE according to the

designated format and OPE displays this on LCD, LED. OPE’s sensing is also transmitted to the main through

UART line and then the main drives necessary operation.

OPE PBA consists of U1(MICOM, HT48R50),LCD, key matrix, LED indicators. Refer to OPE Schematic

Diagram and Wiring Diagram sections of this manual.

• Signals from the key matrix are delivered to U1 input pin group (D1~D6)

• U1 pin 48 (TX DATA) is the UART code sent to MAIN PBA.

• Display from the controller is received at U1 pin 5(RX DATA).

• LCD drive signals are sent from U1 P2-x pin group, P3-4~P3-6 pins.

• Machine status LED drive signals are sent from U1 LED0~LED7.

LIU WIRE CONNECTS Main B’D’s MODEM AND LINE PARTS, AND IMPEDANCE MATCHING (AC, DC),

RING DETECTION PART and LINE SEIZURE (DIALER).

3-7-2. DC MATCHING PART

Normal movement range of LIU is 12mA ~ 9mA.

Adapting CTR21 standard, the regulation limits to 60mA CURRENT ﬂow through the terminal.

Therefore, select (*:for EU PIT) Option to connect necessary items then the current through LIU will not

exceed 60mA.

• CTR21 Standard(Europe) : 12mA~60mA • OTHER Standard (U.S.) : 12mA~90mA

DC has a character to pass through the LINE. And with Q1 (VN2410) GATE section’s LINE INPUT corrent

and Q1 Source connection to R20, can be decided as follows :

• -VDCR = VL1 + ILINE X R20

(VDCR : Tip-Ring CD Voltage, ILINE :

Current ﬂow)VL1:Line Input Voltage, VL1=VBD1+VCE(Q2)+VDS(Q1)

3-7-3. AC MATCHING PART

Basic LIU’s AC IMPEDANCE is 600 and uses R47. 48. C36 to possibly control combined IMPEDANCE.

• U.S. Usage : A terminal IMPEDANCE Æ 600W(±30%)

• CTR21 : A Terminal IMPEDANCE Æ 270+750W//150nF

3-7-4. DIALER PART

*MF DIAL

DTMF Dialing is controlled by MODEM and should be selected by appropriate LEVEL and On-off Time output

based on each countries’ own National speciﬁcation.

• Freq. Tolerance : ±1.5%

High Group : 1209, 1336, 1477, 1633Hz

Low Group : 697, 770, 852, 941 Hz

*DP DIAL

Controls from MAIN through / DP-Terminal.

for U.S.Usage, set time to DF signal of 40:60 M/B. DP signal is made of U6 (pcb817). The DC current which

ﬂows thru Q2 Base is regulated by On/Off switch and turns to DP dial signal with a COUPLER.

• CTR 21 does not have telephone capability but has the number 3 and 4 Line Connection. No DP condition

but possibility to get approval only on DTMF Dial based terminal.

3-7-5. RING DETECTION PART

RING SIGNALS from the LINE section (TIP, RING)are further passed through C5, R3, ZD1, and ZD2 and

ends up at U9, (PC 814). U9 then detects above RING SIGNAL and passes the output to MAIN B’D. The wilre

3-8-2 AC Input Stage

AC Input power path is consist of the Fuse (F1) for AC current limit, the Varistor (TNR1) for by-passing high

Voltage Surge, the discharge resistor(R1), the AC Impalse Noise Filtering Circuit (C2, C4, LF1), the Common

Mode Grounding Circuit (C5, C6), the 2’nd noise ﬁlter (C7, LF2), and the thermistor (TH1).

Wher power is turned on, TH 1 limits Inlush-Current by it’s high resistanle, and When it’s temperature rise, it’s

resistance become about Zero ohm.

3-8-3 SMC(Switched Mode Control)

The AC input voltage is rectiﬁed and ﬁltered by BD1 and C10 to create the DC high voltage applied to the pri-

mary winding of T1, Q5 pin #1 is driven by the SMPS device IC2, IC2. auto-starts and chops the DC voltage.

The U502 is PWM SMPS IC and has internally a SMC(switched mode control) IC and a MOSFET output

stage. The SMC IC has a Auto-restart without a Power Supply for the IC and a Thermal Shutdown function

and so on. R4, R5, C11, D1 clamp leading-edge voltage spikes caused by transformer leakage inductance.

The power secondary winding(Pin #5~6)is rectiﬁed and ﬁltered by D8, D9, L2, C33, C34 to create the 5V out-

put voltage. The bias winding(Pin #9~8)is rectiﬁed and ﬁlltered by D2 and C12 to create U502 bias voltage.

The secondary output 5V is regulated through the path of the voltage divide by R34, R35.

3-8-4-2. The Concept of Fixed Lamp Control

For ﬁxed lamp control, the logic unit "fuser on" control signal and SMPS unit DC power must be supplied.

This circuit turns on only when "fuser on" sends the signal and the DC power is supplied.

The following explains how the ﬁxed lamp control circuit works.

logic unit "fuser on" sends trigger current to triac driver PC3 LED, then the infrared ray is detected by PC3

photo detector. Next, YC3 triac is conducted.

The conducted current sends trigger input to triac SY1 gate. At this point, SY1 is conducted and AC power

is supplied to ﬁxed lamp. Lamp is turned on and temperature rises.

As this ﬁxed lamp control circuit uses the AC voltage ("+" and "-" are repeated) as the power supply, it used

two-way triac (SY1), which has advantage over one-way SCR considering the price, size and reliability.

Triac's gate can be triggered by either forward or reverse signal. Once triac is turned on, it will not be con-

trolled by gate signal, but will be continuously on until the current between major terminals decreases below

the holding current. In other words, you cannot turn it off with reverse signal unlike SCR. This prop-

erty is called current-voltage threshold rise rate (commutation: dv/dt). In AC power control

application, triac has to turn off conduction in each zero crossing or switch it twice in each cycle. This switch-

ing operation is called commutation. It is possible to turn off the triac at the end of half cycle by eliminating the

gate signal when the load current (IL) is gained at the level equal to or lower than holding current. When

triac commutes off-line, the direction of the voltage of the both ends of triac will be reversed and increase

up to the maximum value of line voltage (VAC). At this point, the width of rise rate will be determined by dv/

dt and overshoot voltage, by the circuit. When triac commutes off-line, the voltage of both ends of triac will

have the same voltage as the line voltage.
