1. Precautions

Please read the following carefully to prevent any accidents and not to damage the unit during service.

1-1 Safety Precautions

1-2 Precautions on Disassembly and Reassembly

1. Safety Precautions

There are some electric or machinery parts with safety

related property. If the parts replaced are different from

the original, the safety may not function. Even if the part

could allow higher voltage than that of the part used, do

not replace it and use a regular product clarified in spec-

ifications.

2. Be careful not to leave a switch, a cover or a safety device

out when reinstalling or assembling the product after

repair.

3. Replacing Precautions

Do not change or add parts as you like. You cannot ben-

efit from such a remodeled product at your will during the

term of guarantee.

4. You must replace overheated or damaged parts or cords

with regular products. Please solve the problem causing

any damage or overheating and troubles beforehand.

Especially mind the safety on the part with this

mark.

You must use regular parts described in specifica-

tions for the parts inflammable and where the cur-

rent can be flown. Otherwise any hazard such as

an electric shock or a fire could occur.

Very careful precautions should be taken when replacing

parts. Before replacing, please check cables because you

cannot put the cables that you removed for replacing parts

into the proper place if you would not make sure of where

they were connected and in which condition.

Please do the following before disassembling

for a repair or replacement of parts.

1. Pull out paper cassette, printer cartridge installed.

Especially careful not to be scratched by the surface of

developer or not to expose them to light.

2. Turn the power switch off.

3. Take out the power plug, printer cable from the printer.

4. Use only the same type of part as original when replacing

parts.

5. Do not force to open or fasten plastic material compo-

nents.

6. Be careful that small parts such as screws should not get

in the printer.

7. When disassembling, assembling, also observe small

components are located in place.

8. If you uncover and turn the machine over to replace some

parts, toner or paper particles may contaminate the LSU

window. Protect the LSU window with clean paper.

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.

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 sta-

tic electricity.

1. Immediately before handling a semiconductor compo-

nent or semiconductor-equipped assembly, drain off any

electrostatic charge on your body by touching a known

earth ground. Alternatively, employ a commercially avail-

able 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 conductive surface, such

as aluminum or copper foil, or conductive foam, to pre-

vent electrostatic charge buildup in the vicinity of the

assembly.

3. Use only a grounded tip soldering iron to solder or desol-

der ESDs.

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

der 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 dam-

age 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 conductive foam, aluminum foil, or a compa-

rable 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 com-

pletely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged

replacement ESDs. Normal motions, such as the brush-

ing together of clothing fabric and lifting one’s foot from a

carpeted floor, can generate static electricity sufficient to

damage an ESD.

4-3-22 The Printer is Not Working (1)

• Description While the power is turned on, the printer is not working at all by the PRINT command from the com-

puter.

Check and Cause Solution

1. Perform the Printer Self-Test.

2. Check if the PC and the printer cable are properly

connected.

3. Check if the printer driver is correctly installed.

1. Check the power source of the printer first and perform the

Printer Self-Test. If the test results in printing, it is considered

as there is no problem in the printer itself. If the printer is not

working, the function may be defective (not due to S/W), so

take another proper measure.

2. Check the status of the printer connection, and if it is defec-

tive, replace the printer cable (USB or Parallel).

3. Check the connection between PC and printer port (USB port

or LPT port). Check if the printer driver at the Printers on the

Control Panel is installed. If the printer driver is properly setup,

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

way is to try printing from the Memo pad, the WINDOWS

basic program. Sometimes, the print out is normal within the

WINDOWS basic programs, but it may not work in a specific

program. In such case, reinstall the printer driver.

Troubleshooting

Samsung Electronics

4-3-23 The Printer is Not Working (2)

• Description Even after the Print command, there is no response at all or the printing speed is low.

Check and Cause Solution

It may due to wrong setup of the environment rather

than malfunction of the printer itself. And in case that

abnormal characters are printed out, also check the

environment setup.

1. Secure the hard disk space.

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

the hard disk.

3. Reboot the system, and try printing again.

1. Not working with the message 'Insufficient memory' means

that the hard disk space to store the print information is insuf-

ficient rather than the RAM insufficiency. In this case, secure

more space for the hard disk.

Secure more space for C drive by using the Disk utilities pro-

gram at 'PROGRAM - ACCESSORIES - SYSTEM TOOL'

from the Start menu.

2. The connection of the cable or printer port is not properly

setup.

3. If characters are printed abnormally, the cable or the printer

driver may be defective. Turn the PC and printer off, and

reboot the system to try printing again. If the problem still

exists, double click to install the printer from My Computer

and right-click the mouse, then click 'Test Print' button at the

bottom of the file information tab. If normal characters are not

printed again, the cable must be defective so replace the

cable with a new one.

4-3-24 Abnormal Printing

• 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 strange characters are only printed,

it may be the printer driver problem.

Check and Cause Solution

1. Printer driver error

2. Error due to insufficient memory.

(The printing job sometimes stops during proceeding

or not completed due to insufficient memory.)

1. Check 'My Computer - Printers'.

(If the printer driver is installed not compatible with the

printer currently installed or an error occurs in the driver

file, remove the existing driver and reinstall the printer

driver by using the 'Printer Add' menu.

2. This is because of an insufficient virtual memory.

(It does not mean the actual capacity of RAM but the

space of hard disk.)

Delete unnecessary files to secure enough space of the

hard disk and try printing again.

Name of Printer Port :

To reinstall the printer driver, do after removing the current driver.

• While installing the driver, Set and PC should be connected.

(The printer setup may be wrong if they are not connected during installing.)

• The SCX-1100 Model supports all the USB/Parallel Print, select the USB Port when using

the USB, while select the LPT Port when using the Parallel.

4-3-25 Spool Error and Release of Spool Error

• Description pool (Simultaneous Peripheral Operations Online) refers to process the document to be read and

stored in the hard disk or the mass storage media, and then to be printed at more convenient time.

While the printer is outputting other file, the file requested to output is undergone to be spooled in the

hard disk, the spool error may occur if a problem occurs in this process.

First, delete the Spool Data if the Spool Error occurs.

Check and Cause Solution

I. Insufficient space of the hard disk set as the default

spool directory.

2. If the previous printing out error is not solved.

3. In case a collision with other program is expected.

4. When an application program or the printer driver file

is damaged.

5. If some of OS related files are damaged or malfunc-

tioning due to virus infections.

6. The memory is less than that recommended by the

OS.

1. Delete unnecessary files to provide more hard disk

space and try printing job.

2. Since there may be some journal files with the exten-

sion ***.jnl, delete them and reboot the WINDOWS to

restart printing job.

3. Exit all other programs except the program currently

using, if possible, and print again.

4. Delete the printer driver completely and reinstall it.

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

damaged files and reinstall the program, then try print

ing again.

6. Add memory to the PC.

How to delete the data in the spool manager :

In the spool manager, the installed drivers and the list of all the documents waiting to be

printed are shown. Select the data of the document to be deleted and select Document menu

--> Delete.

If you intend to delete the current document being printed, the data being transferred to the

printer will be printed out and then the document will be removed. Before choosing the docu-

ment data, the document menu is still inactive.

Or Hold the document in the waiting list and repeat the routine as the above or exit the Spool

manager

3-3-2 S3C46MOX(Jupiter3) FUNCTION DESCRIPTION

3-3-2-1 SYSTEM CLOCK

There are two ways of Clock input method. One is the method to make Master Clock(MCLK) at the internal PLL by con-

necting X-tal and Capacitor to the outside, and another method is to use MCLK(When inputting 40MHz) directly, which

supplies maximum 40MHz Clock to the EXTCLK terminal(PIN65). The range of frequency being input in case of using

X-tal is limited to 4MHz~10MHz. This system uses SSCG(FS781) with a 10MHZ X-tal outside to make MCLK, and sup-

plies Clock to the XIN terminal(PIN67) of ASIC by expanding Spectrum with bandwidth about 1.5% in comparison with

the basic frequency by using this IC. Inside the ASIC, the PLL makes 66MHz MCLK signal, which is the basic operation

frequency of the System. Also, this PLL makes 48MHz, the operation frequency of USB Controller.

3-3-2-2 DATA AND ADDRESS BUS CONTROL

1. /RD & /WR

/RD & /WR SIGNAL are synchronized with the inside MCLK(66MHZ) and becomes active to Low.

These signal are Strobe Signal used to Read or Write data when each Chip Select becomes active connected to

/RD,/WR PIN of RAM, ROM, OA-980.

2. CHIP SELECT (/ROMCS, /IP_CS,/MED_CS,/SCS0,/SCS1)

3-3-2-3 EXTERNAL DMA part

The function of this part is to bring data from external

DEVICE(OASIS:U21) by using GENERAL DMA. If DMA

REQUEST(/IP_REQ) is sent from external DEVICE to

S3C46MOX(JUPITER3:U15), DMA ACKNOWLEDGE

SIGNAL(/IP_ACK) is activated and the GENERAL DMA is

driven, so READ STROBE(/RD) in the external DEVICE to

bring data from the external DEVICE requiring CHANNEL.

To transfer this DATA to the DESTINATION MEMORY, the

ADDRESS of the DESTINATION MEMORY, CHIP

SELECT and WRITE STROBE(/WR) are generated to

store.

That is, if the EXTERNAL DMA is required by the external

DEVICE, S3C46MOX(Jupiter3:U15) responds to drive the

inside DMA CONTROLLER and then allocate GENERAL

DMA to external CHANNEL so that the data may be trans-

ferred to MEMORY TO MEMORY or external DEVICE TO

MEMORY.

• For more details, see the circuit description, see the circuit

description part of IMAGE PROCESSOR (5.3).

3-3-2-4 DRAM control part

Since S3C46MOX(Jupiter3) has the DRAM CON-

TROLLER build-in, it may be used by connecting DRAM

with external memory.

The Control mode of DRAM CONTROLLER provided by

S3C46MOX(Jupiter3) is available for EARLY WRITE,

NORMAL READ, PAGE MODE, and BYTE/HALF WORD

ACCESS, and is supported even by EDO DRAM,and

SDRAM as well as, Fast page DRAM.

This system uses SDRAM, and the signal used for

READ/WRITE uses /RD,/WR signal used for SYSTEM

BUS CONTROL. It is supported with auto REFRESH and

also by the Self-refresh mode for DRAM

BACK UP. It con-

sists of 2 Banks connected to co

mmon /SCS[1:0], /SCAS,

/SRAS, /SCLK, /SCKE, /DQM[1:0], each of them may use

up to 2M ~ 32M HALF WORD.

In this system, 2 MB is applied as system memory. The

area of DRAM is specified in the DRAM MEMORY MAP of

Fig. 1, while the related TIMING DIAGRAM in Fig. 5, 6, 7,

8, 9.

3-3-2-5 RTC (REAL TIME CLOCK) part

The RTC related circuit part is not applied because the fax

function is not applied, in this system.

3-3-2-6 PARALLEL PORT INTERFACE division

S3C46MOX(Jupiter3) has the Parallel Port Interface part

enabling Parallel Interface with PC.

This part is connected to PC through Centronics Connector

in this system, which consists of /ERROR, PE, BUSY,

/ACK, SLCT, /INIT, /SLCTIN, /AUTOFD, /STB and 245DIR

as the part generating the main control signal used to drive

PARALLEL COMMUNICATION. Data transmission

method between this part and PC supports the method

specified in P1284 Parallel Port Standard

(http://www.fapo.com/ieee1284.html) of IEEE.

That is, the Compatibility mode, the fundamental transmis-

sion method of print data, supports the Nibble Mode(4bits

data) supporting the Data Uploading to PC, Byte

Mode(8bits data), and ECP(Enhanced Capabilities Port : 8

bits data transmission & receiving) supporting two-way

high speed transmission to PC. The Compatibility mode

and ECP mode may be simply explained as follows.

The Compatibility mode is generally called Centronics

mode and is the protocol used for transmitting data by most

of PC. The ECP mode provides two-way high speed com-

munication as the protocol suggested for improved com-

munication with peripheral equipments such as printer and

scanner.

The ECP mode provides two types of cycles in two-way

transmission. They are data and command cycles.

Command cycle again has Run-length count and Channel

addressing types.

First, RLE (Run Length Encoding) type, having 64-fold

compressibility, is available for the real time data compres-

sion, and is used usefully for printer and scanner, which

have to transmit large capacity of raster image having a

series of same data. Next, Channel Addressing is pro-

posed for addressing single structure of multi-device.

For example, although the printer channel is processing

the printer image when the fax/printer/scanner have one

structure like this system, they may use parallel port for

another use. This system does not apply to the parallel port

Interface.

3-3-2-7 USB INTERFACE PART

1. USB function description

As the mode of implementing low cost express PC

Interface, USB was applied. At USB, PC plays the role of

route hub simultaneously by existing in the highest level as

the host. That is, the device supporting each USB is con-

nected centering on PC.

The device is available for Interface for the maximum of

127. USB cable is composed of total of a set of twisted pair

and 2 power lines. Cables have two types.

One is used for express transmission of 12Mbps and may

be extended as long as 5m. The part for implementing USB

function is included in S3C46MOX(Jupiter3).

For Interface of USB, pull-up of 15KΩis interfaced to the

data line of high level instruments, and, among data lines

of lower level instruments, pull-up resistance of 1.5KΩis

interfaced to any one.

At this time, D+ line is pulled up for Full Speed device, and,

for Low Speed device, D-line is pulled up. For upper level

instruments(Host, HUB) speed of device is classified inter-

faced to low level by detecting any one among D+ and D-.

If both lines are in the level of GND at the same time, device

is judged that low device is not interfaced. In the transmis-

sion mode of USB, there are

(1) Control transmission,

(2) Interrupt transmission,

(3) Bulk transmission, isochronous transmission

Control transmission is for Host to find out configuration

information from USB device. This is conducted when

device is interfaced. Interrupt transmission is used when

small quantity of data is sent periodically. Interval value

may be known from device in the case of initial setting. Bulk

transmission is valid in case of trying to transmit data in

large quantities or in case of transmitting them accurately.

Isochronous transmission should be assured of bandwidth,

and is used when transmitting large quantities of informa-

tion. Data in voice is used where delay is not allowed but

small error is allowed. At USB coding mode and bit stup-

ping are being conducted. First, in case original data is 1,

bit shall not change, and only when original data is 001, it

shall be inverted. Only while data is 1, 1 and 0 shall be

repeated. Also, in case 1, original data, is continued in 6 bit,

0 shall be inserted, Also, in the 1st phase of packet, data in

the synchronized pattern shall be sent. About more

detailed information regarding USB, see

http//:www.usb.org.

2. operation description

This system, when Host and USB cables are connected,

and when +5V is detected in power detector inside chip

and Vbus(U15-98), 3.3V comes out through Pull-uP termi-

nal. This is also connected to D+ in pattern of hardware and

supports Full-speed. Utilizing Configuration Endpoint,

EPO, in USB controller, Plug & Play function is operated.

Exchange of information between PCs is accomplished

through D+(U15-95) and D-(U15-96) terminals. This termi-

nal decides transmission speed depending on connection

of regulator output in USB controller, and decides size of

signal following USB and SPFC. Signal of general D+ and

D- terminals are same as Figure 10-3.

3-3-2-8 HEAD control part

1. Entire description

As part to drive INKJET HEAD, it is composed of ACLK,

AGATE, LDCS, LATCHCTL, PCLK, PDATA[3:0], PLOAD,

PENABLE signals for controlling Spitfire of CR B’D gener-

ating signal, which is driving Nozzle of Head, and

PH_ID[1:0] and OK2Print signals receiving from Spitfire.

Here,HEAD being used here is DOUBLE HEIGHT PRINT

HEAD, and MONO is configured with 208 NOZZLE, and

COLOR is with 192 NOZZLE.

2. A-LINE driving circuit

13 Address Lines are input into 13 Address Counters in

sequence at Rising edge of ACLK signal, which is input

serially into Spitfire. Output of this Counter was connected

to each A-line driver, and this driver output becomes A-line

signal. The sequence of signal input into Address Counter

is decided by ADIR, and if it is ADIR=0, it is input in

sequence of A13A1, and if it is ADIR=1, in sequence of A1

=> A13. AGATE signal is used to reset Address Counter. If

it becomes AGATE=1, A-Line output becomes Low state.

The cycle of ACLK is 1.5ß¡ in minimum, and Sink current of

each Driver is 60mA.

3. P-LINE drive circuit

P-Line values are clocked to 4-bit Serial to Parallel Shift

line NO. of fitting value at Rising Edge of PCLK. These val-

ues are latched to Holding register at Rising Edge of

PLOAD. PLOAD Pulse Duration is 50n, and P-line value of

Holding Register is done AND with PENABLE signal in

order to generate appropriate Fire Pulse. PLCK is available

for handling as much as 4MHz. Drive Current of P-line is

400mA. Data of P1°≠P4 is shifted to PDATAO, that of P5-

P8 shifted to PDATA1, that of P9-P12 shifted to PDATA2,

and that of P13-P16 shifted to PDATA3.

4. Control Signal

• The signal loaded on PDATAO - PDATA2 at Rising edge

of LATCHCTL(Latch Control Nibble) is used as function

as follows in Spitfire.

- PDATA0 == ADIR —> Low : ACLK is operated in Count

Down, High : ACLK is operated in Count

Up.

- PDATA1 == When Fault Test —> High, check whether

P-Line of Head became short with GND.

- PDATA2 == When Print Head ID Check —> high,

make sure that Check mode is set, and,

after that, by using the PDATA0~PDATA2

LIne, make A1-A3 signal for sending, and

Head ID shall come out with PH_IDn out-

put. At this time ID could be displayed only

if each Substrate heater is turned on.

• The signal loaded into PDATAO-PDATA3 at Rising

edge of LDCS(LoadHtrcs) signal is used in the follow-

ing functions in Spitfire.

- PDATA0 == BLKHTR—> High : Turn on Substrate

Heater of Mono Head.

- PDATA1 == COLHTR—> High : Turn on Substrate

Heater of Color Head.

- PDATA2 == nHSM—> Low : Enable Select Signal of

Mono Head.

- PDATA3 == nHSC—> Low : Enable Select Signal of

Color Head.

When Substrate Heater is turned on, Over-current Check

circuit is operated, automatically, and,if the current is above

750mA, the printer stops operation after OK2PRT

becomes low.

3-3-3 RESET CIRCUIT

This system is configured with PRIMARY RESET(/POR) of

Power Reset, Reset by WATCH DOG TIMER, external

PRIMARY RESET, and SECOND RESET(/_F_POR)

which was done AND. PRIMARY RESET SYSTEM is used

for resetting MAIN CONTROLLER(U15) when System

Power is authorized, and SECOND RESET resets FLASH

MEMORY(U7). Figure 15 below is BLOCK DIAGRAM

related to the reset of entire system.

When +3.3V reaches 3.1V so that system may operate,

POWER MONITOR(U13) moves to High(+3.3V) after

maintaining low(OV) in the degree of 50mS-200mS output

while monitoring it. This Reset signal is input into MFP

CONTROLLER(S3C46MOX(Jupiter3 : U15) right away,

and MFP CONTROLLER becomes awake. And it releases

/F_POR after MCLK 1 clock.

3-3-3-1 POWER MONITOR ( U13 )

Since +3.3V power supplied to XC61FN3112MR is unsta-

ble, when it becomes 3.1V(3.038V~3.162V), it is checked

as the POWER FAILURE. And the output terminal of

XC61FN3112MRF becomes LOW(0V),it is applied to

S3C46MOX(Jupiter3)(U15), and RESET(LOW ACTIVE) is

operated When S3C46MOX(Jupiter3) Reset is cancelled,

FLASH MEMORY connected to /F_POR of

S3C46MOX(Jupiter3) is Reset together. Output terminal of

XC61FN3112MRF is pulled up 100KΩin the structure of

Open drain.

3-3-3-2 WATCH DOG OUTPUT (/F_POR)

Since WATCH DOG TIMER, which is Programmable

Counter in S3C46MOX(Jupiter3) is set as disable for INI-

TIAL STATE, it shall be set as Disable so that it won’t oper-

ate, and after it is initialized for operation, it shall be reused

3-5-2 OA-980 DESCRIPTION BY FUNC-

TIONS

3-5-2-1 Clock Control Section

Internal drive frequency operates classified into two parts.

Almost all On-chip µ Controller(8bit) Module drives by

Main_clock, and Printer Interface Section(PO) only drives

by Base_clock. Main_clock and Base_clock may be set

with frequency each desires by receiving Clock supplied

from outside by PLL Logic.

At present, system Main_clock and Base_clock are each

set in 48MHz, and may be checked at SDRAM_CLK of

SDRAM(U27). Clock supplied from outside does not use

separate crystal, but 48MHz is supplied by IP_CLK,

CLK_Out of Jupiter3(U15).

The one which pulled up Main_EXT(pin46) and

Base_EXT(pin43) is the Option using internal PLL, and, at

the time of Pull-up, it does not use internal PLL, but just use

Clock supplied to Main_CLK(pin45) and Base_CLK(pin42)

as Main_clock and Base_clock.

3-5-2-2 Internal Microcontroller

8bit RISC Microcontroller is built-in, and Address area

which Micro-controller control is 64kbyte. At the same time

when cache is built in for control of more efficient SDRAM,

it possesses Hook function, namely the internal Boot ROM

256byte required for self-initialization function, too.

1. Memory Map

2. Power On/Off Reset

• Power On Reset

Depending on the signal state of Reset_L(pin35), OA-

980 may be reset in the manner of hardware. Reset is on

at “Low” state and, at “High” state, Reset is Off.

Accordingly, in order for OA-980 to operate normally,

after the System initialization, the /IP_RST of

Jupiter3(U15-31) shall be converted to “High” state. In

order for safe Hardware Reset to be accomplished, it

should be maintained in “Low” state for more than 1000

Main_clock(10uS).

• Power Off Reset

PWR_down(pin107), for SDRAM(U27) to advance to the

Self Refresh Mode Reset_L(pin35) at the Power Safe

Mode, shall advance to the Reset Mode earlier than the

minimum of 1uS. This System does not use it.

3. Hook function : Self-initialization function

In case self ROM is connected to OA-980 as in Figure (15),

although the execution file is downloaded to SDRAM, the

execution file is initialized by receiving download from

Memory. This execution file is the ROM File supporting so

that all functions of Image processing related to OA-980 as

well as register setting value required for initialization(Copy,

PC scan, MultiMediaCard Print) may operate normally.

3-5-2-3 Host Interface Section

(HI : Jupiter3 interface section)

Unlike the existing DuoIP sequence, OA-980 exchanges

Command and data with Jupiter 3 in the Multiplexed 8bit

Bus(data & address) mode. Namely, it does not receive

Address and Data simultaneously, but receive data after

receiving Address first using Data Bus of Jupiter3.

HI Section also supports the data movement in the DMA

mode. Accordingly, when transmitting large capacity of

Image data(RGB data of MultiMedCard), it uses the DMA

mode.

1. Multiplexed 8bit Bus(data & address) mode

nce Jupiter3 may not support Multiplexed 8bit Bus(data &

address) mode used by OA-980, it configured a circuit addi-

tionally so that mutual Interface may be possible by making

required signal using two NOR GATE(UR16) and one OR

Gate(U40).

As REG_ADDR_VAL(pin27) signal is the signal for OA-980

to play a role of informing that value input into 8bit of OA-

980 Bus is not Data but Address value, when ADDR(10) is

“High” and /IP_CS, /WR “Low,” “High” shall be generated as

shown in the circuit diagram. See figure (16). At this time,

since /WR_L(pin31), the Write signal of OA-980, should be

maintained in “High,” the signal shall be generated in case

actual Write is accomplished with one OR Gate(U18),

namely, only when ADDR(10) is “Low,” When

REG_ADDR_VAL (pin27) is “High,” input the Address value

of OA-980, and when “Low, from the standpoint of Jupiter3,

it may Read or Write One Byte Data using two Cycles by

Reading or Writing relevant Data of (to) Address.

2. DMA mode

DMA mode is the method of Reading or Writing Data in

Block unit by activating two DMA Channels of OA-980

respectively. When A8 or A9 is “Low” and when /IP_CS is

“Low,” GDMA of Jupiter3 Reads or Writes in Memory to

Memory mode, as the appropriate DMA Channel is activat-

ed. See Figure (17). Of course, it performs required DMA

mode before DMA is accomplished.

3-5-2-4 Scanner Interface Section(PI)

It directly controls 16bit ADC and 600dpi color CCD con-

nected to CCD, processes Shading and Gamma correc-

tion, the basic course required for Image process of RGB

12bit(8+4bit) data transferred from ADC, then performs the

function of storing the data in SDRAM of OA-980 through

MI Block.

3-5-2-5 Image Processing Section(IP)

After performing color compensating required for the

System

for RGB digital data input, it conducts the role of

converting to

CMYK data printable. IP Block consists of four

Modules mainly.

- Photo text detect

- Zoom and dpi adjust

- Color space conversion

- Half toning and loss less JPEG

3-5-2-6 Memory Interface Section(MI)

MI Block consists of four Channels, located between exter-

nal SDRAM(U27) and blocks inside OA-980, and is con-

trolled so that the flow of all data may be accomplished more

efficiently.

3-5-2-7 JBIG Comp & Decomp Section

By condensing Image data processed at Blocks into JBIG

algorithm and save them in external SDRAM(U27), it shall

have Memory domain used more efficiently. Naturally, even

when moving Image data which was condensed to JBIG, to

other block, it is conveyed to Image data freed from conden-

sation.

3-5-2-8 Rotate and Inkjet Engine Section

After Image CMYK Data which ended all image processing

is converted to Format so that Inkjet Printer Engine may

print, it plays the role of saving them on the external

SDRAM(U27).

The Data stored in the external SDRAM(U27) is transferred

to Head Control Part of Jupiter3 through MI and HI Block of

OA-980 by DMA of Jupiter3, and then printed by Spitfire.

3-5-2-9 Printer Interface Section(PO)

When the Image process required for PC Scan (See Fig.

19) is completed, OA-980 requests that /IP_REQ signal in

PO_Block should take the Scan Image Data from the

External DMA Block of Jupiter3(U15). The External DMA

Block of Jupiter3(U15) generates not only /IP_ACK signal

to bring Data by Byte as the unit but also /RD signal to bring

the Data. The External DMA Block of Jupiter3(U15) stores

the Data in SDRAM(U9) and then restore /IP_ACK as

"High" to receive a next Data/.

As DMA Timing properties between Jupiter and OA-980 do

not match, /IP_ACK0 is separately created to prevent BUS

collision by using one OR-Gate(U18-3) so that OA-980 may

use the BUS only in /RD in the way of inputting the /ACK

signal into OA-980 only when /RD is actually produced,

while Jupiter3 may use in /WR, as shown in the Timing of

Fig. 18. That is, since OA-980 sends Data to BUS during

/ACK signal section, BUS collision occurs between DMA of

Jupiter3 and /WR section, where /RD, /WR are all carried

out during /ACK.

3-6 CCD MODULE and ADC Part

3-6-1 CCD MODULE GENERAL

DESCRIPTION

CCD Module has the structure transferring RGB data to

be converted into the digital signal through ADC on the

basis of the level of analog signal to OA-980, the Image

Processor, which divides the signals reflected by emitting

light to document into R, G, B data according to each fre-

quency.

The voltage used in the CCD Module are 11.75V for ana-

log signal of RGB, 5V as input for CCD and other ele-

ments. The input part of CCD Module consists of

CCD_TG, CCD_CLK1,CCD_CLK2 and CCD_RS, the

output of OA-980(U21), CCD_TG controls the scan line,

which is set variously according to copy mode, color and

mono, and scan resolution. CCD_CLK1 and CCD_CLK2

are clocks by each pixel, CD_RS is reset signal of each

pixel. Since the pixel of 1/2 cycle of CCD_CLK1 and

CCD_CLK2 is sampled, color signal sends RGB data to

output for 1/2 cycle, and controls the pixel of 1/2 cycle for

mono. Therefore, the output signal from the CCD Module

classifies the signals received by RGB channel according

to each frequency band and uses each video

signal(CN1) as the input data of ADC(U16).

TG, CLK,RS TO BE USED ARE AS FOLLOWS.

3-6-2 ADC

Description ADC(U16) is the input data that change the

analog signal of RGB to the digital signal of 16bit (8bit +

8bit) so that it may be used as the input of OA-980(U21),

image processor, while VSMP(_ADC_VSMP) is used as a

sampling signal for each pixel of RGB. That is, it controls

the signal for one pixel like CLK1,CLK2 of CCD and its

maximum sampling rate is of color 2MHz mono 4MHz.

MCLK(ADC_CLK) is CLK for the signal of VSMP, the rela-

tion between MCLK and VSMP is as follows. The relations among SCK(ADC_SCK), SDI(ADC_SDI) and

SEN(ADC_SEN) are equivalent to the control bit for regis-

ter setting to mode, output signal appears in 8bit unit from

OP0 to OP7, and 5V/3.3V will be used as the power source.

3-8-1 OVERVIEW

OPE BOARD is separated from the Main Board functional-

ly, and operates entire Micom(HT48C5A-000Z) in the

Board. OPE and Main exchange mutual information using

UART(universal asynchronous receiver/transmitter) chan-

nel. Also, Resetting of OPE is designed to control at the

Main. Micom in OPE performs key-scanning and LCD, LED

display control, and senses document detect, Scan position

and so on. When information is generated from OPE(key

touch, sensor level change, etc.), it sends specific code

coping with the situation to Main, and the Main operates

system by analyzing this code. If the Main tries to display

data on OPE, the Main sends data to OPE via UART line

on the basis of the format specified, and OPE displays it to

LCD.

• This system does not apply document detect and SCAN

position.

3-8-2 UART

OPE and MAIN exchange information mutually by using

asynchronous communication mode(UART), and in full

duplex. Band rate is 9600bps, and uses 7.37MHz resonator

as oscillating element. It engages in communication with

8bit data without parity bit. UART line has two lines for Tx

and Rx, and the default level is in the 'high' state. For com-

munication, the start bit(low level) is transmitted before 8bit

data. When the data transmission(8bit) is completed, the

high state is maintained as the stop bit(high level) is trans-

mitted. Data is transmitted from LSB(DO), and MSB(D7) is

transmitted lastly.

3-9-1 UART COMMUNICATION

1) UART TX FORMAT

Codes for change of KEY, TOUCH, SENSOR LEVEL and

so on are transmitted in single code without PRE/POST

DATA, and OK or Error messages to check if communica-

tion is performed properly are also transmitted in single

code. Provided that, in case the Main requested a certain

value(LCD, other register) particularly, data requested is

transmitted followed by sending Post Data('EOH') first.

2) UART RX FORMAT

Data being received will be arranged to be received accord-

ing to the following specified format to know what data they

are.

DATA are received in the sequence of A,B,C, and D, and

the Check sum to check if the transmission is made prop-

erly will be found by doing XOR data from A to C.
