4. Cautions on Transmitting Documents

• Documents written in yellow, greenish yello w , or light b lue ink cannot be transmitted.

• Ink, glue, and correcting fluid on documents must be dry before the documents can be transmitted.

• All clips, staples and pins must be removed from documents before transmission.

• Patched (taped) documents should be copied first on a copier and then the copies used for transmission.

• All documents should be fanned before insertion into the feeder to prevent possible double feeds.

5. Automatic Document Feeder Capacity

Number of pages that can be placed into the feeder at anytime is as follows:

Normal size: max. 50 sheets (14 lbs - 20 lbs) Special size: single sheet only (manual feed)

NOTES: • If you need to send or copy more 50 pages, place the ad-

ditional pages and carefully in the feeder just before the last page is scanned. Do not try to force them in, as this may cause double-feeding or jamming.

• If your document consists of several large or thick pages

which must be loaded one at a time, insert each page into the feeder as the previous page is being scanned. Insert gently to prevent doublefeeding.

6. Readable Width & Length

The readable width and length of a document are slightly smaller than the actual document size.

Note that characters or graphics outside the effective document scanning range will not be read.

• Readable width

[4] Installation

1. Site selection

T ake the f ollowing points into consideration when selecting a site f or this model.

ENVIRONMENT

• The machine must be installed on a level surface.

• Keep the machine away from air conditioners, heaters, direct sun-

light, and dust.

• Provide easy access to the front, back, and sides of the machine. In

particular, keep the area in front of the machine clear, or the original document may jam as it comes out after scanning.

• The temperature should be between 10° and 35°C (41° and 95°F).

• The humidity should be between 30% and 85% (without condensa-

tion).

ELECTRICITY

AC 120 V, 60 Hz, grounded (3-prong) AC outlet is required.

Caution!

• Connection to a power source other than that specified will cause

damage to the equipment and is not covered under the warranty.

• If your area experiences a high incidence of lightning or power surges,

we recommend that you install a surge protector for the power and telephone lines. Surge protectors can be purchased at most telephone speciality stores

2. Installing the printer cartridges (Toner cartridge: FO-47ND/Drum cartridge: FO-47DR)

Follow the steps below to install or replace the toner and drum cartr idges.

• The ini tial star ter toner car tridge inc luded with th e fax machine can print about 3700 letter-size pages (4% coverage of e ach page).

• The replacement toner cartridge (FO-47ND) can print about 7500 letter-size pages.

• The drum cartridge (FO-47DR) can print about 20,000 letter-size pages.

Press the green release and open the pr int compartment cover .

• Caution! The fusing unit inside the print c om partment becomes very hot during operation. Be careful not to touch the inside of the compartment.

TELEPHONE JACK

A standard RC11C telephone jack must be located near the machine. This is the telephone jack commonly used in most homes and offices.

• Plugging the fax machine into a jac k which is not an RC11C jack may

result in damage to the machine or your telephone system. If you do not know what kind of jack you have, or need to have one installed, contact the telephone company.

If the machine is moved from a cold to a warm place...

If the machine is moved from a cold to a warm place, it is possible that the reading glass may fog up, preventing proper scanning of documents for transmission. To remove the f og, turn on the power and wait appro ximately 2 hours before using the machine.

If you are replacing the toner cartridge, remove the old cartridge and dispose of it according to local regulat ions. Go directly to Step 6 if you are only replac ing the toner cartridge and not the drum car tridge.

• If you are replacing the drum cartridge but not the toner cartri dge, remove the toner cartridge and place it on a sheet of paper.

If you are replacing the drum cartridge, remove the old cartridge

and dispose of it according to local regulations.

• Output of the soft switch list is started.

Inhibition of data change

(This is also applicable for the optional setting.) In the following case, it is inhibited to change the data with the key

error buzzer.

• Switching ON/OFF of ECM during the use of image memory.

• Switching OFF to ON of the print hold function when the print

hold pass code has not yet been registered.

• Clearing the print hold pass code when print hold function is ON.

• Switching ON/OFF of the print hold function during the use of

memory such as in the case of substitute receiving.

• OFF to ON of telephone billing function which is using the image

memory is used (Note: In the existing set, the telephone billing code function is specified from OFF to ON when the timer system communication (including the batch communication) is set.) Here, the memory is usable when the telephone billing code function is on. It can be set from ON to OFF while the memory is used. How e v er, if setting is practically changed even once, it can not be returned from OFF to ON.

• Switching ON/OFF of PC interface function during the use of im-

age memory.

• OFF to ON of department control function during use of image

memory. (Note: In the existing set, the department control function is set from OFF to ON when the timer communication (including the batch sending) or the memory hold is set.)

• ON to OFF of continuous serial polling function when the con-

tinuous serial polling is started. (Note: In the existing set, "ON to OFF of the continuous serial polling function when the continuous serial polling is registered" has been applied, but the conditions are now moderated. However , registration is impossib le to the program of the new continuous serial polling when the continuous serial polling function is OFF.)

• In addition, change of all soft switches during communication

Linked change of data (This is the same even in the optional setting.)

• When the department control function is off, the multi TTI func-

tion and telephone billing code function are turned off.

2) Print area

According to the size of the specified sheet, the effective printing area is printed.

3) ROM & RAM check

The sum value of ROM, the work and the back-up RAM are checked. The RS232C interface is also checked. If any error occurs, the buzzer will inform it. (Ref er to the following table). Finally , the result will be printed. This diagnosis does not check the flash memory. The flash memory is checked with the flash memory test.

Number of buzzer sounds Device checked Remarks 1 time <Short sound> ROM Main 2 times <Short sounds> Integrated ROM Main 3 times <Short sounds> SRAM Main 4 times <Short sounds> D-RAM Main

For the short and long sounds, one pattern is as follows.

Main system: 0.5 seconds ON/0.5 seconds OFF Sub system: 1.00 second ON/0.5 seconds OFF

The execution state of checking is as follows. Moreover, the list of the

• Soon after this mode is activated, press the FUNCTION key for 5

seconds or more, and the display mode of the distance between pages will be activated. Then, set up the sending paper and select the image quality, and then press the START key, and operation will be started. Be sure to press the FUNCTION key prior to the START key. If the FUNCTION key is not pressed but the START ke y is pressed, it will operate in the same matter as in the existing auto feeder mode. If the START key is pressed, the FUNCTION key will be invalid hereafter. Therefore, the display mode of the distance between pages and the existing mode can not be changed.

• While the sending paper is read, the image quality key can be

input. STD/FINE/S-FINE modes are usable. However, the same operation of FINE will be selected if the intermediate tone is set.

• The image quality , the length of the sending page read, the page

distance to the next sending paper and the total of the sending papers read are shown on the display.

• When the stop key is pressed or 100 sending papers are read,

the content shown on the display will be totally output as the list after the remaining sending papers are discharged.

5) Aging mode

If any document is set up in the first state (when started), copying will be executed. If it is not set up, "check pattern 1" of the print diagnosis is output at the intervals of 1 time/60 minutes. (A total of 10 sheets are output.)

7) Optical adjust mode

Turn off the COVER SHEET FUNCTION.

Set line equivalence at 0 km.

After the check, it is necessary to be sure to return the aforementioned soft switches into the initial state. (Clear the memory with the diagnosis.)

11) Memory clear

Clear the back-up memory to initialize the soft switches. The flash memory will be initialized. Then, the initialized list be output.

12) Flash memory

The flash memory is checked. The ordinary memories (ROM, SRAM, DRAM) are checked in the ROM & RAM check process. The write/read test is taken every block to print the result.

When an error occurs, the following error buzzer will sound.

Number of buzzer sounds Check device 9 times <Short sounds> Flash memory(Option)

During operation of this diagnosis, dual operation is not possible at all. If this is excessively repeated, it will shorten the life of the flash memory .

13) All FAX/TEL. entry mode

The function is used to simplify the registration of FAX/TEL No. during aging.

The diagnosis mode is activated. If anything is not registered in the

Rapid number 01 or any program or group is not registered, it will pass the diagnosis without doing anything.

The FAX/TEL number (including the substitutive destination) of the

Rapid number 01 is copied to the Rapid numbers 02 thru 48.

F AX number of the Rapid number 01 is copied to SPEED key numbers

001 thru 200.

FO-4700U FO-47UC

If any chain dial is not in the Rapid number, the Rapid numbers 02 thru 48 and SPEED key numbers 001 thru 200 are registered in the group number 01. If any chain dial is set, the group will be not produced but the chain dial setting alone of the Rapid number 01 will be reset. (In all others except the Rapid number 01, the chain dials will be continuously set as they are.)

(16th and subsequential letters of the destination name registered in the Rapid number 01 will be discarded.)

14) Dept. passcode

The department passcode list is printed.

15) Conf. passcode

The confidential passcode list is printed. Differing from printing of one box alone soon after registration, the confidential passcodes of all boxes are printed.

16) Print hold code

The print lockout passcode No. is printed.

17) Memory set mode

The set and dump list of the memory content is output.

• The address (8 digits (P) generally including the bank information is

input, and the data of 2 digits is continuously input. Inputting is done in the hexadecimal mode. The ten-key is used for 0 thru 9, and the alphabetic keys A (RAPID 01 thru 06) are used for A thru F.

• During data inputting, the address can be moved forward and back-

ward one byte by one byte with " " and "#". (The address prior to the address 0 is looped as the maximum address.)

• The V alidity of the address is not chec ked. Accordingly, writing/ read-

ing operations are possible in the address of the memory not assigned, the address of ROM and so on. (Howev er , as practical, writing is not done, and the data content runs short each reading.) Though writing is possible in the flash memory, a little time is required. It is also necessary to take care that the life of the flash memory is excessively shortened if much data is written in the flash memory. Since it may run away depending the written content, take minute care for the writing address.

• When the REPORT key is input, the memor y dump list is produced

from the displayed address (here, it is limited at the 16-byte boundary address (address with end 0) which does not exceed the specified address and is just in front.). The dump list is output to a maximum of 99 pages. If any data of one page can be repeatedly developed and printed, the list is sufficient. But it is not desired that the content of plural pages are developed in the memory once and are then printed. If the ST OP k e y is pressed, it will pass to the diagnosis after the page which is now being printed is completed printed. If the address exceeds the maximum address, it will return to the address 0 and printing will be continued.

18) Stamp aging

Diag mode is left though it doesn’t have this function.

The mode is used to inspect whether dialing is accurate in two kinds of dial modes . All data which can be dialed in this mode are automatically called up in both PB mode and DP mode.

When this mode is activated, the following operations will be automatically executed . Whether the dialed content is right or not is judged with the external instrument which is connected to the line cable.

After shift to the FAX diagnosis mode, press RAPID 24. (Also switch the display with the [ ] and [#] keys.)

Press the START key.

Turn on CML, and dial the following in the PB mode. 1, 2, 3, 4, 5, 6, 7, 8, 9, , 0, #

Turn off CML 500 mS alone.

Dial the following in the DP mode. 1, 5, 9, 0

After dialing, turn off CML.

This mode uses the ordinary auto dial. (Accordingly, the signal sending time and minimum pause are all the same as ordinary. The measurement result in this mode is completely all the same as in the ordinary dial mode. Moreover, the same process as abo ve is also done in the dial test mode which is executed in the product check mode.

20) Copy diag mode

In order to shorten the process time during production, this mode is used to automatically switch the copy mode. Three men us are provided.

1. 1Set up two documents. (In case of two documents or more, there is no problem.

Press the START key.

Copy 1st document in the fine mode/density A UTO . (One sheet is printed in the ordinary copy mode.)

Copy 2nd (subsequential) document in the intermediate tone mode/density DARK. (In the ordinary copying mode, one sheet is printed when the RESOLUTION key is pressed three times.)

When copy test is tried during production or is checked in two modes (fine and intermediate tones), this mode is provided to reduce the troublesome work which makes the operator stand aside to change the mode. Accordingly, the fine and inter mediate tones are merely switched, and the mode is not switched to another mode. (Input of the image quality/ density key is invalid.)

2. Try the copy in the mode fixed at COPY REDUCE 95% and fine

mode/density AUTO. At this time, don’t change the soft key of COPY REDUCE. (Input of the image quality/density key is invalid.)

3. Continuously try the above items 1 and 2.

The mode is used for aging related to the printing. In this mode, the following modes are provided.

Blank paper aging mode (ALL WHITE AGING)

Whole black print aging mode (ALL BLACK AGING)

4% printing aging mode (4% AGING) After selecting the paper-pass aging mode in the print diagnosis mode, input the number of each mode above with the ten-key, and the mode will be executed. The detailed specifications of each mode are described as follows. Here, the operation in each mode is stopped only when the STOP key is pressed by the operator or a pr inting-impossible error occurs.

• Blank paper aging mode

In the mode, printing is continued in the whole white (white paper)

printing pattern until the STOP key is pressed by the operator . (In the printing area)

• Whole black printing aging mode

In the mode, printing is continued in the whole black (whole black)

printing pattern until the STOP key is pressed by the operator . (In the printing area)

Rapid key 06: Bias adjust mode

The mode is used to adjust the printing density of the printed image. The image printing density is adjustable in seven steps of 1 to 7. For details, refer to the following table. (For selection, use the keys 1 thru 7.)

FO-4700U FO-47UC

Rapid key 08: Life all clear

The mode is used to clear the life counter of the printer of the counter of the auto feeder.

Note: The counter shows the operational state of the printer (e.g. ho w

many sheets have been printed since start of use?). The ordinary memory does not reset the counter. Accordingly, it is necessary to reset this counter in addition to the ordinary memory clear if the content in the memory on the control PWB is broken because of PWB repair, etc. (In the production stage, it is necessary to execute this in the last process.)

Rapid key 09: Life entry mode (For Serviceman temporary counter)

The mode is used to set a desired value for the judgment value (alarm judgment counter value) of the general purpose life counters 1 thru 3 of the printer. If the life of a consumable part (developer,imprinter, etc) is set, the model which has the error display and RMS function will inform RMS when the counter reaches the set value. For setting, proceed with the following procedure.

When the life counter setting mode is selected, the following will be displayed.

For checking, retry this mode. Note: This counter indicates the printer use conditions such as numbers of printed pages from the beginning of use. In the normal memory clear condition, the counter will not be reset. In conditions including damaged memory contents caused by repairing the panel, this counter should be reset or cleared in addition to the ordinary memory clear.

The cursor blinks at the top data. Three counters can be selected with the "#" and " " keys.

In the state 1 , input a desired setting number of 6 digits with the tenkey .

After input of 6 digits, shift to another counter with the "#" and " " keys as necessary. When all necessary counters are completely input, press the START key.

"STORED" will be displayed with the set values stored into the memory. For checking, retry this mode.

Note: The counter shows the operational state of the printer (how many

sheets have been printed since start of use? and others). The ordinary memory does not reset the counter. Accordingly, it is necessary to reset the counter or do the clear process in addition to the ordinary memory clear if the content in the memory on the control PWB is broken because of PWB repair, etc. (In the production stage, it is necessary to execute this in the last process.)

Rapid key 10: Top adjust mode

As the method to adjust the top margin for printing, adjust top margin adjusting VR on the PWB. If this mode is used at this time, adjustment is possible without the printing test every time when VR is turned.

To input B4 documents into the memory, therefore, the B4 documents must be reduced to letter size (A4) or the both ends of the B4 documents will be cut off to input the center letter-size (A4) portion. This switch provides the selection.

0: Reduced to A4 size and inputted. 1: Both ends are cut off and the center portion (A4 size) is inputted.

2. Document feed operation

1) As shown in Fig.1, the document set in the hopper (the front sensor is on) is fed with the pay-out roller and paper feed roller which rotate together with the pulse motor.

2) When a specified number of pulses are received from the document sensor after the document lead edge is sensed, scanning will be started.

3) When a specified number of pulses are received from the document sensor after the document rear edge is sensed, scanning will be ended to discharge the document to the tray.

4) If the front sensor is on (the document is set up in the hopper), the next document is supplied and fed nearly when the last document is completely read and discharged. If the front sensor is off (no document is set up in the hopper), the drive will be stopped when the document is discharged to the tray.

5. PAPER PATH

Paper can be fed into the printer from the Multi Purpose Tray (250 sheets) or from the Manual Feed Port (1 sheet).

Installing the Paper Cassette Unit (500sheets) adds another feeding method.

The paper fed by the Paper Take-Up Roller is transported to the Image Transfer Roller, Fusing Roller and then Paper Exit Roller. After this, the paper is fed out onto the Print Tray.

Print Exit

6. PAPER TAKE-UP SECTION 6-1. Multi-Purpose Tray

When the Paper Take-Up Solenoid (SL1) is energized, the drive of the Printer Motor (M1) is transmitted to the Paper Take-Up Roller via the Paper Take-Up Clutch (one-wa y clutch) to turn the Paper Take-Up Roller one revolution. At the same time, the Depressing Cam turns and lifts the Paper Tray to feed the top (first) sheet of paper.

The Fixed Separating Pad is used for the paper separation system. It prevents the second or later sheets of paper from being fed together with the top sheet.

The printer has no paper size detecting mechanism. It recognizes the paper size by the paper length which is calculated by the P aper Take-Up Sensor (PS1) activation timing. Therefore, paper having different widths are recognized as the same paper size if they have the same length

The PC Drum is charged with static electricity before laser exposure. The Rotating Charge Brush and the Precharge-film are used for the charging method.

The rotating brush charging and the Precharge-film charging generate little ozone in the printer. Because the charge is directly applied to the PC Drum, the PC Drum can be charged by low voltage. At the same time, PC Drum can be charged stably and evenly.

The Precharge-film supplies the charge to the Rotating Charge Brush to improve the charging efficiency.

The Rotating Charge Brush is turned by the drive of the Printer Motor (M1) via a gear.

Laser exposure is the process of creating an invisible static image on the PC Drum by the laser beam emitted from the Print Head Unit.

In the sub-scanning direction (vertical direction) When the printer receives the PRINT signal, the Polygon Motor and the Printer Motor rotate and the paper is fed into the printer. The printing in the sub-scanning direction is started when the Printer PWB (PWB-A) sends the VIDEO signal to the Print Head a certain time after the leading edge of the paper activates the Paper Sensor (TOD signal). The print starting position of the 2nd line is decided by delaying the VIDEO signal sending timing.

In the scanning direction (horizontal direction) The SOS Sensor is installed on the Laser Diode Control PWB (PWBD) to unify the laser emission timing for each scan line.

10. IMAGE TRANSFER 10-1. Overview

Image transfer is the process of transferring the toner image created on the PC Drum in the developing process to paper. Roller Image Transfer is used instead of the Corona Image Transfer as the image transfer method. In the Roller Image Transfer, there is little generation of ozone due to corona discharge. Also, there is no blur of toner because the paper is always pressed by the PC Drum and the Image Transfer Roller.

When cleaning the Image Transfer Roller and before printing, reverse bias is applied.

11-2. Fusing Temperature Control Circuit

The Thermistor (TH1) detects the surface temperature of the Upper Fusing Roller and inputs that analog voltage into IC2-78. Corresponding to this data, the Heater Lamp ON/OFF signal is output from IC2-55, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature. When the Heater Lamp is not turned OFF even if the Thermistor detects a high temperature malfunction (if the surface temperature of the Upper Fusing Roller exceeds 210˚C), the signal from IC2-79 changes from L to H to turn OFF the Heater Lamp forcibly.

11. FUSING 11-1. Overview

The toner image transferred onto the paper is securely fixed to the paper. A heat roller system is used as the fusing system. The toner image is fused by the Heat roller heated by the Heater Lamp, and securely fixed by the pressure between the Heat Roller and Backup Roller. A Thermistor (TH1) detects the Heat Roller temperature. The Thermostat (TS1) contacts open when the temperature becomes approx. 195˚C and shuts down the power to the Heater Lamp.

The following three different temperature control modes are pro vided for the Heater Roller.

1) Mode 1 The temperature is controlled to maintain 105˚C during standby and 185˚C during printing. If this mode continues for 45 seconds, it will shift to mode

2) Mode 2 The temperature of the Heat Roller falls gradually to about 175˚C from about 185˚C. If this mode continues for 208 seconds, it will shift to mode 3

3) Mode 3 The temperature is controlled to maintain 105˚C during standby and 175˚C during printing. Unless an error occurs or an top cover is opened, this mode is maintained.

The above functions are controlled by getting an access to the interface memory in the modem through the data bus from CPU (IC27) of the control PWB. The interface memory is composed of 32 8-bit registers, and is controlled with the bank switch. Accordingly, the register is selected by the register selection signals (RS4 to RS0) of 5 bits and chip selection signal (CS). The major content controlled b y these registers is as follows.

1) Configuration register

Mode setting of V17, V29, V27, G2, FSK and tone transmission.

2) Option register

Equalizing method of equalizer, carrier detection threshold, addition of echo suppressor protect tone, and setting of transmission/reception mode.

3) Others

G2AGC control, tone frequency setting, and so on. Moreover, data is read from these registers through the data bus to

monitor the statuses of the modem such as tone detection, training pattern detection and so on.

Next, transmission/reception operation is described. During sending, the sent data is given from the control block to the

modem through the data bus. Then, it is modulated and sent to LIU PWB with SIGTX signal. During receiving, the received data is sent from LIU PWB to the modem with SIGRX signal and is demodulated. Then, it is sent to the control block with the data bus. The above operation is done with the modem LSI (IC).

In addition to the above functions, the following tone transfer/tone detection functions are also provided.

(8) Gate array (B) block

The block is composed of the gate array (B) and SRAM (2 KByte).

1) LR38292(IC10) ... pin-160, QFP (gate array B)

The device has the following functions.

Printing data process The image data of the page memory for printing is converted into

400 dpi, and the smoothing and contracting processes are applied.

Printer (PCU) interface The control of resetting and so on to PCU and the image data proc-

essed in Item 1 above are synchronized with the signal (HSYNC) from PCU and are transmitted to PCU in the serial mode.

DMA controller

(a)The binary-coded data of the draft transmitted in the serial mode

from the gate array (A) LZ9FJ59(IC17) and read with the scanner are transmitted to the page memory.

(b) The image data which will be printed are read from the page

memory, and the process 1 is applied to transmit the data to PCU in the serial mode.

CODEC (HD813201F) interface

(a)The timing is controlled for CPU to get an access to CODEC. (b)The timing is controlled for CODEC to get an access to the page

memory.

DRAM controller Since DRAM is used for the page memory, and the address, RAS

and CAS are controlled and refresh-controlled.

Panel interface The key input detection on the operation panel, LED lighting con-trol

and LCD display control are executed.

2) LH5116NA-10 (IC3) -- pin-24, SOP (16-Kbit SRAM)

This SRAM is a line memory for the printing data process (resolution power conversion, smoothening and contracting to 404 dpi) of the gate array (B).
