Employing lead-free solder

The Power supply PWB of this model employs lead-free solder. This is indicated by the “LF” symbol printed on the PWB and in the service manual. The suffix letter indicates the alloy type of the solder. Example:

Indicates lead-free solder of tin, silver and copper.

Using lead-free solder

When repairing a PWB with the “LF” symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may result in cold soldered joints and damage to printed patterns.) As the melting point of lead-free solder is approximately 40ºC higher than tin/lead alloy solder, it is recommended that a dedicated bit is used, and that the iron temperature is adjusted accordingly.

Soldering

As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability (flow), to prevent damage to the land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time. Remove the bit as soon as a good flow is achieved. The high content of tin in lead free solder will cause premature corrosion of the bit. To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required. Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their characteristics, making good soldering more difficult. It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be taken to clean the bit thoroughly after each use.

CAUTION FOR BATTERY REPLACEMENT

PRECAUTIONS FOR USING LEAD-FREE SOLDER

FO-4400U FO-CS1

To avoid problems with supplies, please don’t use supplies from other units. Please use new supplies, when supply changes are required.

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 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 specialty stores.

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 jack 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. T o remove the fog, turn on the power and wait approximately 2 hours before using the machine.

2. Assembly and connections

Connecting the power cord

Connect the female end of the power cord to the fax machine as shown. Insert the male end into a 120 V, 60 Hz, grounded (3-prong) AC outlet.

Important!: The fax machine requires its own dedicated power outlet. The power outlet must not be shared with any other devices. In particular, do not use an extension cord to connect multiple devices to the outlet.

Note: If your area experiences a high incidence of lightning or power surges, we recommend that you install surge protectors for the power and telephone lines. Surge protectors can be purchased at most telephone specialty stores.

Data number selection

The cursor position shows the data to be set. Pressing # key or → key moves the cursor to the right. If, however, the cursor is on data number 8, pressing # key or → key shifts the cursor to data number 1 of the next switch number. If the switch number is the final, pressing # key or → key will exit the soft switch mode. Pressing key or ← key moves the cursor to the left. If, however, the cursor is on data number 1, pressing key or ← key shifts the cursor to data number 1 of the former switch number. If the switch number is 1, pressing key or ← key will not move the cursor and the error buzzer will sound.

Data setting method

Press the MENU key, and the data at the position of the cursor will be reversed to 0 when it is 1, or to 1 when it is 0. (If the soft switch can be changed at the bit (Refer to 6.), the error buzzer will sound with the process not received.)

Outputting method of soft switch list

In the soft switch mode, press the REPORT key, and the soft switch list will be output. If the recording paper runs out or is clogged, the key error buzzer will sound with the process not received.

Storage of data

In the following case, the data of the soft switches set will be stored.

• It is shifted to set the next soft switch by pressing the START

switch.

• It is shifted to set the next soft switch with the [#] key.

• It is shifted to set the last soft switch with the [ ] key.

• It is shifted to set another soft switch by inputting two digits as the

switch number. (When 2 digits are completely input.)

• 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.

• 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. However, if setting is practically changed even once, it can not be returned from OFF to ON.

• NAND-Flash (optional) is valid only when the optional memory is

mounted.

The NOR flash memory test is executed.

The concerned alarm buzzer sounds only when the error occurs.

The NAND flash memory test is executed.

The concerned alarm buzzer sounds only when the error occurs.

The result is printed.

NOTE:

• 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.

M) All FAX/TEL. entry mode

This is a function to copy the FAX and TEL numbers registered in the one-touch dialing (RAPID) key [01] to the all one-touch dialing (RAPID) key and the all abbreviated number (SPEED DIAL) to simplify the FAX and TEL number registration at the time of aging.

Copy the Fax and Tel numbers (including agency) registered in the one-touch dialing (RAPID) key [01] to all one-touch dialing (RAPID) key.

Copy the FAX and TEL numbers registered in the one-touch dialing (RAPID) key [01] to the all abbreviated number (SPEED DIAL).

In case the chain dial is not set in the one-touch dialing (RAPID) key [01], register the one-touch dialing (dialing) keys [02] – [59] and all abbreviated number (SPEED DIAL) to the group number [01]. In case that the chain dial is set, do not create a group, but cancel only the chain dial setting of the one-touch dialing (RAPID) key [01]. (All except for the one-touch dialing (RAPID) key [01], chain dial is kept set.)

Enter all registered one-touch send (RAPID) keys and speed dial

numbers (SPEED DIAL) on the personal books [01] - [10]. Following this, set the password registration and the password setting to ON, and set the TTI setting to OFF.

The call-receiver names and book names are specified as follows:

(The letters after 16th letter of the call-receiver’s name registered in the one-touch dialing [01] are cut off.) NOTE: Before entering this mode, FAX and TEL numbers must be reg-

istered in the one-touch dialing (RAPID) key [01]. (In case that they are not registered, or a program or a group is registered, it is not executed.)

N) Dept. passcode

The department passcode list is printed.

O) 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.

P) Signal send mode 2

The signals concerned with V.34 & V.8 are checked. After this mode is activated, press the START key, and the signals will be sent in the following sequence. It can be used to check the modem.

[ 1] No signal [ 2] 33600BPS (V. 34) [ 3] 31200BPS (V. 34) [ 4] 28800BPS (V. 34) [ 5] 26400BPS (V. 34) [ 6] 24000BPS (V. 34) [ 7] 21600BPS (V. 34) [ 8] 19200BPS (V. 34) [ 9] 16800BPS (V. 34) [10] 14400BPS (V. 34) [11] 12000BPS (V. 34) [12] 9600BPS (V. 34) [13] 7200BPS (V. 34) [14] 4800BPS (V. 34) [15] 2400BPS (V. 34)

[16] 0 - 300BPS (V. 34) [17] ANSam

Q) 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 through 9, and the alphabetic keys A (RAPID 01 through 06) are used for A through 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 Validity of the address is not checked. Accordingly , writing/ read-

ing operations are possible in the address of the memory not assigned, the address of ROM and so on. (However, 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 memory 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 STOP key 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.

MECHANICAL DESCRIPTION

[1] Mechanical description

1. Facsimile block 1-1. Document feed block and diagram

Fig. 1

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 let 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.

3. Hopper mechanism

3-1. General view

Fig. 2

The hopper is used to align documents with the document guides adjusted to the paper width.

NOTE: Adjust the document guides before and after inserting the docu-

ment.

3-2. Automatic document feed

1) The structure with secure paper feed of the transfer roller and secure separation of the separation rubber plate system is employed. The transfer roller is semicircular as to be rotated only when the paper feed roller is driven with the 2-step paper feed clutch mechanism. Moreover, the separation securely done by running the paper feed and transfer rollers more slowly than the feed roller.

2) Document separation system: Friction + speed reduction ratio + roller backlash separation system

Fig. 3

3-3. Loading the documents

1) Make sure that the documents are of suitable size and thickness, and free from creases, folds, curls, wet glue, wet ink, clips, staples and pins.

2) Place documents face down in the hopper.

• Adjust the document guides to the document width.

• Align the top edge of documents and gently place them into the

hopper. The first page under the stack will be taken up by the feed roller to get ready for transmission. NOTE: 1) Curled edge of documents, if any, must be straighten out.

2) Do not load the documents of different sizes and/or

thicknesses together.

3-4. Documents applicable for automatic feed

NOTE: Double-side coated documents and documents on facsimile re-

cording paper should be inserted manually.

Documents corresponding to a paper weight heavier than 90kg and lighter than 135kg are acceptable for manual feed.

Documents heavier than 135kg in terms of the paper weight must be duplicated on a copier to make it operative in the facsimile.

5. P APER P A TH

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

Installing the 2nd Paper Cassette Unit (FO-CS1) (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.

6. PAPER TAKE-UP SECTION 6-1. Multi-Purpose T ray

When the Paper Take-Up Solenoid (SL1) is energized, the drive of the Main Motor (M1) is transmitted to the Paper Take-Up Roller via the Paper Take-Up Gear (one-way clutch) to turn the Paper Take-Up Roller one revolution. At the same time, the Depressing Cam turns and lifts the Paper Lifting Plate, and the first (top) sheet of paper on the tray is fed to the printer. The Fixed Separating Pad is used for the paper separation system. It prevents the second and subsequent sheets of paper from being fed together with the top sheet. The actual length of the paper is detected using the period of time through which the Paper T ake-up Sensor (PS1) remains energized (or through which the paper moves past the sensor) and it is determined whether the actual length matches the paper length specified by the controller.

The PC Drum is charged with static electricity before laser exposure. The Drum Charge Brush and the Pre-charge Film are used for the charging method. The Drum Charge Brush and Pre-charge 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. In addition, the charg applied to the PC Drum is stable and even. The Pre-charge Film supplies the charge to the PC Drum before being charged by the Drum Charge Brush to improve the charging efficiency. The Drum Charge Brush is turned by the drive of the Main Motor (M1) via a gear. The electric potential on the surface of the charged PC Drum is approximately-800 V.

8. LASER EXPOSURE

Laser exposure is the process of creating an invisible static charge image on the PC Drum by the laser beam emitted from the Print Head Unit. This process is controlled as follows in order to appropriately time image printing.

In the sub-scanning direction (vertical direction)

· When the printer receives the PRINT signal, the Polygon Motor and the Main Motor rotate and the paper is fed into the printer.

· The printing in the sub-scanning direction is started when the Controller PWB 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 for 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 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 corona image transfer as the image transfer method.

· In 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.

· The residual electric potential on the paper is dissipated via a discharge needle.

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 (H1), and securely fixed by the pressure between the Heat Roller and Backup Roller.

11-2. Fusing Temperature Control Circuit

· The Thermistor (TH1) detects the surface temperature of the Heat Roller and inputs that analog voltage into IC4-78. Corresponding to this data, the Heater Lamp (H1) ON/OFF signal is output from IC4-55, causing the Heater Lamp (H1) to turn ON or OFF to control the fusing temperature.

· When the Heater Lamp (H1) is not turned OFF even if the Thermistor (TH1) detects a high temperature malfunction (if the surface temperature of the Heat Roller exceeds 230°C), the signal from IC4-79 changes from L to H to turn OFF the Heater Lamp (H1) forcibly.
