not allow paper clips, pins or other foreign objects to fall into the machine these could cause a

short circuit leading to an electric shock or fire hazard.

5. Never touch the plugs on either end of the power cable with wet hands, this can cause elec-

tric shock. When servicing the machine, remove the power plug from the wall socket.

6. Use caution when inserting or removing the power connector. The power connector must be

inserted completely otherwise a poor contact could cause overheating and possibly leading to

a fire. When removing the power connector grip it firmly and pull.

7. Take care of the power cable. Do not allow it to become twisted, bent sharply round corners

or otherwise damaged. Do not place objects on top of the power cable. If the power cable is

damaged, it could overheat and cause a fire or exposed wires could cause an electric shock.

Replace a damaged power cable immediately, do not reuse or repair the damaged cable.

Some chemicals can corrode the coating on the power cable, weaken the cover or exposing

wires causing fire and shock risks.

8. Ensure that the power sockets and plugs are not cracked or broken in any way. Any such

defects should be repaired immediately. Take care not to cut or damage the power cable or

plugs when moving the machine.

9. Avoid damp or dusty areas, install the machine in a clean well ventilated location. Do not

position the machine near a humidifier. Moisture and dust build up inside the machine can

lead to overheating and cause a fire.

10.Do not position the machine in direct sunlight.

11.Do not insert any metal objects into the machine through the ventilator fan or other part of the

casing, it could make contact with a high voltage conductor inside the machine and cause an

electric shock.

Handling Precautions

The following instructions are for your own personal safety, to avoid injury and so as not to dam-

age the machine

1. Ensure the machine is installed on a level surface, capable of supporting its weight. Failure to

do so could cause the machine to tip or fall.

Introduction

Phaser 3435 5/08 v

2. The machine contains many rollers, gears and fans. Take great care to ensure that you do

not catch your fingers, hair or clothing in any of these rotating devices.

3. Do not place any small metal objects, containers of water, chemicals or other liquids close to

the machine which if spilled could get into the machine and cause damage or a shock or fire

hazard.

4. Do not install the machine in areas with high dust or moisture levels, beside an open window

or close to a humidifier or heater. Damage could be caused to the machine in such areas.

5. Do not place candles, burning cigarettes, etc. on the machine, these could cause a fire.

6. The fuser unit works at a high temperature. Use caution when working on the machine. Wait

for the fuser to cool down before disassembly.

Assembly / Disassembly Precautions

Replace parts carefully, always use Xerox parts. Take care to note the exact location of parts and

also cable routing before dismantling any part of the machine. Ensure all parts and cables are re-

placed correctly.

Please carry out the following procedures before dismantling the machine or replacing any parts.

1. Check the contents of the machine memory and make a note of any user settings. These will

be erased if the mainboard is replaced.

2. Ensure that power is disconnected before servicing or replacing any electrical parts.

3. Disconnect printer interface cables and power cables.

4. Be sure to remove the print cartridge before you disassemble any parts.

5. Only use approved spare parts. Ensure that part number, product name, any voltage, current

or temperature rating are correct.

6. When removing or re-fitting any parts do not use excessive force, especially when fitting

screws into plastic.

7. Take care not to drop any small parts into the machine.

8. Handling of the OPC Drum

- The OPC Drum can be irreparably damaged if it exposed to light.

Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandes-

cent room lighting. Exposure for as little as 5 minutes can damage the surface’s photocon-

ductive properties and will result in print quality degradation. Take extra care when servicing

the machine. Remove the OPC Drum and store it in a black bag or other lightproof container.

Take care when working with the covers (especially the top cover) open as light is admitted to

the OPC area and can damage the OPC Drum.

- Take care not to scratch the green surface of OPC Drum Unit.

If the green surface of the Drum Cartridge is scratched or touched the print quality will be

compromised.

Introduction

ESD Precautions

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” components.

The techniques outlined below should be followed 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 precautions.

1. Immediately before handling a semiconductor component or semiconductor-equipped

assembly, drain off any electrostatic charge on your body by touching a known earth ground.

Alternatively, 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.

2. After removing an electrical assembly equipped with ESDs, place the assembly on a conduc-

tive surface, such as aluminium or copper foil, or conductive foam, to prevent electrostatic

charge buildup in the vicinity of the assembly.

3. Use only a grounded tip soldering iron to solder or desolder ESDs.

4. Use only an “anti-static” solder removal device. Some solder removal devices not classified

as “anti-static” can generate electrical charges sufficient 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 protective packaging until immediately before

installing it. Most replacement ESDs are packaged with all leads shorted together by conduc-

tive foam, aluminium foil, or a comparable conductive material.

7. Immediately before removing the protective shorting material from the leads of a replacement

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 unpackaged replacement ESDs. Normal motions,

such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor,

can generate static electricity sufficient to damage an ESD.

Table 1:

Fault Signs Cause & Check Solution

Light image and par-

tially blank image

(The life is ended.)

• The printed image

is light or unclean

and untidy.

• Some part of the

image is not printed.

• Periodically a noise

as "tick tick" occurs.

1. If the image is light or

unclean and untidy printed

image -Shake the print car-

tridge and then recheck.

(1)NG: Check the weight of

the print cartridge

(2)OK: Lack of toner, so the

life is nearly closed.

2. Some part of image is not

printed -Shake the print car-

tridge and then recheck.

(1)NG: Check the weight of

the print cartridge and clean

the LSU window with a cotton

swab, then recheck.

(2)OK: Lack of toner, so the

life is nearly closed.

3. Periodically a noise as "tick

tick" occurs - Measure the

cycle and the weight of the

print cartridge.

4. White vertical stripes on the

whole screen or partly: Check

the weight of the print car-

tridge.

1. All of 1, 2, 3 above-If it

become better by shaking,

replace with a new print car-

tridge after 50-100 sheets in the

closing state of the life span.

2. In case of 2-If it becomes bet-

ter after cleaning the LSU win-

dow, then the print cartridge is

normal. (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 print cartridge

has been nearly exhausted.

(Purchase and replace with a

new print cartridge after using

about 200 sheets at the point of

occurrence)

4. In case of 3-This is a phe-

nomenon caused by lack of

toner, so replace with a new

print cartridge.

Toner Contamina-

tion • Toner is fallen on

the papers periodi-

cally.

• Contaminated with

toner on prints partly

or over the whole

surface.

1. Toner is fallen on the paper

periodically.

(1)Check the cycle of the fall-

ing of the toner.

(2)Check the appearance of

both ends of the print car-

tridge OPC drum.

2.The centre of the printed

matter is contaminated with

toner.

(1)Check whether foreign

substances or toner are stuck

to the terminal (contact point)

of the print cartridge.

(2)Check whether the state of

the terminal assembly is nor-

mal.

1. If both ends of the OPC drum

are contaminated with toner:

Check the life of the print car-

tridge.

2. Check whether it could be

recycled.

3. If it cannot be recycled:

Replace the print cartridge.

Image Quality

Phaser 3435 5/08 3-25

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 print cartridge

rollers are contaminated with

foreign substance or paper

particles.

(1)38mm interval: Charged

roller

(2)95mm interval: OPC cycle

2. If white spots occur in a

black image at intervals of

95mm, or black spots occur

elsewhere, the OPC drum is

damaged or foreign sub-

stance is stuck to the surface.

3. If a black and white or

graphic image is partially bro-

ken at irregular intervals, the

transfer roller's life has been

expired or the transfer voltage

is abnormal.

1. In case of 1 above -Run OPC

Cleaning Mode Print 4-5 times

repeatedly to remove, refer to

GP 5. Especially check foreign

substance on the OPC surface,

then remove them with a clean

gauze moistened with IPA (Iso-

propyl Alcohol) not to damage

OPC if necessary. 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 38mm -Replace

the print cartridge.: at intervals

of 95mm - Remove foreign sub-

stance.: Broken image -Replace

the print cartridge 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 trans-

fer voltage and readjust if differ-

ent.)

Recycled product • Poor appearance

of the print cartridge.

• Unclean and rough

printouts. • Bad

background in the

image.

1. Poor appearance of the

print cartridge.

(1)Check the damage to label

and whether different materi-

als are used.

(2)Check the appearance of

parts of the print cartridge,

such as frame, hopper.

2. Unclean and rough print-

outs.

(1)Check whether foreign

substance or toner are stuck

to the terminal (contact point)

of the print cartridge.

(2)Check whether the state of

the terminal assembly is nor-

mal.

1. In case of 1

(1)If there is an evidence of dis-

assembling the print cartridge.

(2)If materials other than normal

parts of the print cartridge are

added or substituted.

2. In case of 2 -If there are any

abnormality in connection with

the situation of 1.

(1)It occurs when the print car-

tridge is recycled over 2 times.

(2)If toner nearly being expired

are collected to use, it is judged

as the recycled print cartridge.

substance or toner are stuck

to the terminal (point of con-

tact) of the print cartridge.

(2)Check whether the terminal

assembly is normal.

2. Totally contaminated black.

(Black image printed out)

(1)Check whether foreign

substances are stuck to the

terminal (point of contact) of

the print cartridge and the

state of assembly. (Espe-

cially check the charged roller

terminal.)

3. The printed image is dark

and ghost occurs.

(1)Check foreign substance

attached to the terminal (point

of contact) of the print car-

tridge and the state of assem-

bly. (Especially check the

developing roller terminal.)

1. All of 1, 2, 3 above

(1)Remove toner and foreign

substances adhered to the con-

tact point of the print cartridge.

(2)The contact point of the unit

facing that of the print cartridge

also must be cleaned.

(3)If the terminal assembly is

unsafe: • Fully stick the terminal

to or reassemble it after disas-

sembling. • Disassemble the

side plate and push the terminal

to be stuck, then reassemble it.

2. In case of 2 It is a phenome-

non when the OPC drum of the

print cartridge is not electrically

charged. Clean the terminals of

the charged roller, then recheck

it.

3. In case of 3 It is a phenome-

non as the developing bias volt-

age of the print cartridge. Clean

the terminals of the developing

roller, then recheck it.

LSU (Laser Scanner Unit)

The LSU unit is controlled by video controller. It scans the video data received from video control-

ler with laser beam by

using the rotation principle of the polygon mirror to create the latent image on the OPC drum. It is

the core part of LBP. The OPC drum rotates as the same speed as the paper feeding speed. It

creates the /HSYNC signal and sends it to the engine when the laser beam of the LSU reaches

the end of the polygon mirror, and the engine detects the /HSYNC signal to arrange the vertical

line of the image on the paper. After detecting the /HSYNC signal, the image data is sent to the

LSU to arrange the its margin on the paper.

The one side of the polygon mirror is one line for scanning.

Sensor Input Circuit

• Paper Empty Sensing

The Paper empty sensor (Photo Interrupter) on the HVPS informs the state of paper to

CPU whether it is empty or not with operation of the actuator.

When cassette is empty, it detects the fact by reading the E20 of CPU, and then informs

the fact by displaying the RED.

• MP Sensing

By operation of Actuator on the frame, an individual MP Sensor (Photo interrupter)

informs the state of paper to CPU whether it is empty or not. It reads the D17 of CPU for

recognizing paper in MP, and paper is fed from MP if there is.

• Paper Feeding/With Print Cartridge Sensing

When paper passes the actuator (feed sensor part), it detects the signal of Photo inter-

rupter, informs the paper feeding state to CPU, and then sprays the image data after cer-

tain time. If it doesn’t detect the feed sensor within 1sec. after paper is fed, paper Jam0 is

occurred (LED will be display RED color). The fact whether the developer is inserted or

not is detected by CRUM. After the developer is mounted, the sub-CRUM can read the

information of print cartridge from contact with CRUM involved in print cartridge. If the

information of print cartridge is invalid, it will show invalid sign on a LCD or LED.

• Paper Exit Sensing

It detects paper state whether paper gets out from the set with operation of exit sensor on

the HVPS and actuator on the frame. Paper detects the on/off time of exit sensor by read-

ing D22 of CPU, and the normal operation or jam information is informed to the CPU.

The paper JAM2 is informed. (LED will be display RED color)

• Cover Open Sensing

The Cover open sensor is located on the HVPS. After the front cover is opened, +24VS

(DC fan, Solenoid, Main Motor, Polygon motor part of LSU and HVPS), which is supplied

to the each unit, is cut off. The cover-open sensing is operated by the D23 of CPU. In

case, the red will be ON for informing the facts to user.

• DC FAN / Solenoid Driving

It is driven by transistor and controlled by D14(FAN MAIN), E16(FAN DUPLEX),

C23(PICK-UP CLUTCH), C18(REGICLUTCH), D15(MPF CLUTCH) of CPU. When it is

high, the fan is driving by turning on the TR, and it is off when the sleep mode is selected.

There are three solenoids, and they are driven by paper pick-up, regi and MPF signal. It is

turned on or off by C23, C18, D15 of CPU. The diode protects the driving TR from the

noise pulse, which is flown when the solenoid id de-energizing. FAN Driving Circuit is

driven by Transistor, and controlled by D14, E16 of CPU.

General Procedures and Information

6-24 5/08 Phaser 3435

• Motor Driving

The main motor driving circuits is on the BLDC Motor Assembly Unit. Main Controller has

the interfacing circuits. There is motor driver IC on the motor control board of Motor

Assembly Unit.

The exit motor driving circuits is formed when the driver IC is selected. The AN44060A

Motor Driver IC is used in this case. The resistance Rs value for sensing and voltage

value for the V reference can be changed by motor driving voltage value. The motor driv-

ing voltage is calculated with the following formula.

The motor driving circuit is formed when the Driver IC is selected. The A3977 Motor Driver

IC is used in this case. The resistance Rs value for sensing and voltage value for the V

reference can be changed by motor driving voltage value. The motor driving voltage is cal-

culated with the following formula.

I = Vref / Rs, wherein Vref is (R1 x 5V) / (R1+R2)

SMPS & HVPS board

The SMPS supplies DC Power to the System.It takes 110V/220V and outputs the +5V, +24V to

supply the power to the main board. The HVPS board creates the high voltage of THV/MHV/Sup-

ply/Dev and supplies it to the developer part for making best condition to display the image. The

HVPS part takes the 24V and outputs the high voltage for THV/MHV/BIAS. The high voltage out-

put is supplied to the toner, OPC cartridge, and transfer roller.

Fuser AC Power Control

Fuser (e-coil) gets heat from AC power. The AV power controls the switch with the Triac, a sem-

iconductor switch. The ON/OFF control is operated when the gate of the Triac is turned on/off by

Phototriac (insulting part). In other words, the AC control part is passive circuit, so it turns the heat-

er on/off with taking signal from engine control part. When the HEATER ON signal is turned on at

engine, the LED of PC501 (Photo Triac) takes the voltage and flashes.From the flashing light, the

Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of Triac

and flows into the Triac. As a result, the AC current flows in the e-coil, and heat is occurred. On

the other hand, when the signal is off, the PC501 is off, the voltage is cut off at the gate of Triac,

the Triac becomes off, and then the e-coil is turned off.

Control Algorithm

• Feeding

If feeding from a cassette, the drive of the pickup roller is controlled by controlling the sole-

noid. The on/off of the solenoid is controlled by controlling the general output port or the

external output port. While paper moves, occurrence of Jam is judged as below.

General Procedures and Information

Phaser 3435 5/08 6-29

Table 4:

•Transfer

The charging voltage, developing voltage and the transfer voltage are controlled by PWM

(Pulse Width Modulation). The each output voltage is changeable due to the PWM duty.

The transfer voltage admitted when the paper passes the transfer roller is decided by

environment recognition. The resistance value of the transfer roller is changed due to the

surrounding environment or the environment of the machine, and the voltage value, which

changes due to the environments, is changed through AD converter. The voltage value for

impressing to the transfer roller is decided by the changed value.

•Fusing

The temperature change of the heat rollers surface is changed to the resistance value

through the thermistor. By converting the voltage value, which impressed to the resis-

tance, to the digital value through the AD converter, the temperature is decided. The AC

power is controller by comparing the target temperature to the value from the thermistor.If

the value from the thermistor is out of controlling range while controlling the fusing, the

error stated in the below table occurs.

• Open Heat Error

When the engine operates the warm-up process, if the temperature of the fixing unit is not

higher than a specified temperature, the engine defines Open Heat Error. When this error

is broken out, the engine stops all functions and keeps the error state. Also, the engine

informs the error status of the main system. And then the error message is displayed at

LCD window or LED informing the error status of the user.

• Low Heat Error

When the engine is at stand-by, printing or warm-up mode, if the temperature of the fixing

unit is lower than the specified temperature at each state and the lower temperature state

is maintained during the specified time, the engine defines Low Heat Error. When this

error is broken out, the engine stops all functions and keeps it at the error state. Also the

ITEM Description

JAM 0 - After picking up, paper cannot be entered due to paper is not fed.

- After picking up, paper entered but it cannot reach to the feed sensor in certain time due to slip,

etc.

-After picking up, if the feed sensor is not on, re-pick up. After re-picking up, if the feed sensor is

not on after certain time, it is JAM 0.

*It is a status that the leading edge of the paper doesn’t pass the feed sensor.

-Even though the paper reaches to the feed sensor, the feed sensor doesn’t be ON.

*It is a status that the leading edge of the paper already passes the feed sensor.

JAM 1 -After the leading edge of the paper passes the feed sensor, the trailing edge of the paper can-

not pass the feed sensor after a certain time. (The feed sensor cannot be OFF)

- After the leading edge of the paper passes the feed sensor, the paper cannot reach the exit

sensor after certain time. (The exit sensor cannot be ON)

*The paper exists between the feed sensor and the exit sensor.

JAM 2 -After the trailing edge of the paper passes the feed sensor, the paper cannot pass the exit sen-

sor after certain time.

engine informs the error status of the main system. And then the error message is dis-

played at LCD window or LED informing the error status of the user.

• Over Heat Error

For overall engine state, if the temperature of the fixing unit is higher than the specified

temperature and the temperature state is kept during the specified time, the engine

defines Over Heat Error. When this error is broken out, the engine stops all functions and

keeps it at the error state. Also, the engine informs the error status of the main system.

And then the error message is displayed at LCD window or LED to inform the error status

of the user.

* To recover the heat error: The heat error recovery is operated automatically when the

error is only caused by Low Heat Error, not the Heat Errors in Warm-up state and the Over

Heat Error. If an error happens, then the engine memorizes a present temperature. In

case of Low Heat Error, the maximum heat is supplied to the fixing unit. When a specified

time is elapsed, the engine detects the temperature again. If the present temperature is

higher than the memorized temperature, the error is recovered. In case of Over Heat

Error, no heat is supplied to the fixing unit. When a specified time is elapsed, the engine

detects a present temperature again. If the present temperature is a specified degree

lower than the memorized temperature, the error is recovered.

•LSU

LSU receives the image data from PVC or HPVC and make the latent image on OPC sur-

face.

It uses the dual beam, LD1 and LD2. But the control method of them is the same.

Just in comparison with the single beam, the dual beam has the half of LSUs frequency.

->The frequency of the dual beam = the frequency of the single beam /2.

The errors related to LSU are as follows:

* By LReady: When the printing is started, the engine drives the polygon motor of LSU.

After the specified time is elapsed, if the motor is not in a ready status, the engine detects

the error that the polygon motor is not in a ready status. If this error happens, the engine

stops all functions and keeps it at the error state. Also, the engine informs the error status

of the main system and the error message is displayed at LCD window to inform the error

status of the user.

* By Hsync: When the polygon motor is ready, the LSU sends out the signal called Hsync

and used to synchronize with each image line. So, if the engine does not detect consecu-

tively the signal for a fixed time, it defines the Hsync Error. If this error happens, the

engine stops all functions and keeps it at the error state. Also, the engine informs the error

status of the main system and then the error message is displayed at LCD window to

inform the error status of the user.

LSU Error Recovery: If the LReady or Hsync error happens, the paper exits out before

hand. The engine mode is changed to recovery mode and the engine informs the main

system of the engine mode. And the engine checks the LSU error. If the error doesn’t hap-

pen, the printing job will be proceeding.

S/W Descriptions

Overview

The software of the system is constructed with

1. Host Software part that the application software operated in Window and Web Environment,

and

2. Firmware parts that is a Embedded software controls printing job.

Architecture

Figure 5

Host Software is made up of

1. Graphic User Interface that offers the various editing functions to user in Host,

2. Driver that translates the received document to a Printing Command language which printer

can understand and transfers data to spooler,

3. Stand-alone Application that offers the various printing application, DMS (Document Manage-

ment System), RCP (Remote Control Panel), Printer Status Monitor, Network Management in

Window system,

4. Web-based-Application that offers the same functions as Stand-alone Application and RDC

(Remote Diagnosis Control) in Web environment.

Firmware is made up of

1. Application (Emulation) that is a interpreter translate data received from Host to a printing lan-

guage (PCL, PS, GDI, etc.) to be able to make the user to take same output as originally one

what composed in Host.

2. Kernel that control and management the whole procedure include of Control flow and Printing

Job before transfer to Engine system.

Data and Control Flow

Figure 6

The above Block Diagram is explained that:

Host Side is made up of

1. Driver that is Windows application software translate printed data to one of printer language

and create spooler file.

2. Web-based Application that offer a various printer additional functions, management of print-

ing job, printer administration, Status monitor to monitoring the printer status by real time in

Web, independent environment on OS.

3. Stand-alone Application that is a similar Window software as same as above 2.

4. Port Monitor that manages the network communication between spooler and Network Inter-

face Card, or various additional application and Network Interface Card, (this is, at first, make

communication logical port, manage the data, transfer them from spooler to network port, and

offer the result of printing).

General Procedures and Information

Phaser 3435 5/08 6-33

Firmware Side is made up of

1. Network Interface Card is that relay the communication between Host and kernel using vari-

ous network protocol,

2. Kernel is that manages the flow control of emulation procedure, receiving data from Host or

Network card and printing with engine & rendering job,

3. Emulation is that interprets the various output data from selected emulation,

4. Engine is that prints rendered bit-map data to paper with required size and type by Kernel.

And then, for Job Spooling function for Multi-User, Multi-Printing that is occurred in Network print-

ing and various additional printing functions, this Kernel use max. 10 Queuing systems in a mem-

ory.

In Printing, the two procedures are

1. Case of using USB Port

• After user start to print the wanted document to PCL string or compressed GDI bit-map

data, Driver translate the all graphic data of it and send data to host spooler. And then the

spooler sends the data stream to the printer via USB port.

• Kernel receives this data from Host, and then select emulation fit to data and start

selected one. After emulation job end, Kernel sends the output bit-map data to Engine

using Printer Video Controller (by clock type for LSU).

• Engine print the received data to required paper with the sequential developing process.

2. Case of using Network Interface Card

• After user start to print the wanted document to PCL string or compressed GDI bit-map

data, Driver translate the all graphic data of it and send data to host spooler.

• If so, Port monitor managing network port receives data from spooler and sends a data

stream to the Network Interface Card.

• Network interface card receives it and send to Kernel part,

• Kernel receives this data from Host, and then select emulation fit to data and start

selected one. After emulation job end, Kernel sends the output bit-map data to Engine

using Printer Video Controller (by clock type for LSU).

• Engine print the received data to required paper with the sequential developing process.

The additional printing function are realized in

(1) Web environment

(2) Window environment.

On addition, Kernel informs a status of printing status and printer status to user made printing job

with the Status Monitor.

GP 7 Tips for Avoiding Paper Jams

By selecting the correct media types, most paper jams can be avoided.

• Ensure that the adjustable guides are positioned correctly.

• Do not overload the tray. Ensure that the paper level is below the paper capacity mark on the

inside wall of the tray.

• Do not remove paper from the tray while your printer is printing.

• Flex, fan, and straighten paper before loading.

• Do not use creased, damp, or highly curled paper.

• Do not mix paper types in a tray.

• Use only recommended print media.

• Ensure that the recommended print side of print media is facing down in the tray, or facing up

in the multi-purpose tray.

• If paper jams occur frequently when you print on A5-sized paper: Load the paper into the tray

with the long edge facing the front of the tray.

GP 11 Print Cartridge Service

It is not guaranteed for the default caused by using other print cartridge other than the cartridge

supplied by Xerox or caused by non-licensed refill production.

Precautions on Safe Keeping of Print Cartridge

Excessive exposure to direct light more than a few minutes may cause damage to the cartridge.

Service for the Life of Print Cartridge

If the printed image is light due to the life of the toner, you can temporarily improve the print quality

by redistributing the toner (Shake the print cartridge), however, you should replace the print car-

tridge to solve the problem thoroughly.

Distinguish Function for Choice Cartridge

An EEPROM is mounted to a cartridge for distinguishing a choice print cartridge. Items written in

below are detected by checking up memory information. If the data of the EEPROM is broken, it

cannot be detected.

1. Detecting existence of a print cartridge: It detects whether a print cartridge is mounted or not.

2. Detecting a serial number of a print cartridge.

3. Detecting a print cartridge supplying company: If it is not original, it is not operated.

4. Detecting an OPC rotating counter: It detects the life span of an OPC drum.
