1.3 Scheduled Servicing Basic Procedure

1. As a rule, provide scheduled servicing every 40,000 prints.2. Before paying a scheduled visit, check the Service Record, and take any

parts likely to need replacement.3. If the machines power plug remains connected to a wall outlet for a

long time in a site where there is much dust, moisture, or oil smoke, itcan collect these elements and trigger insulation failure or fires. Be sureto disconnect the power plug periodically and clean the plug and thearea around it with a dry cloth.

As of October 2002

Steps1. Report to the person in charge. Check the general condition.2. Record the counter reading. Check the faulty prints.3. Make test prints. (1) check the image density against standards;

(2) check for soiling in the white background;(3) check the clarity of characters;(4) check the margin;(5) check the fixing; check for poor registration and

soiling on the back.Standards on margin leading edge: 2.5mm 1.5mm,(single-sided) trailing edge: 2.5mm 1.5mm, left: 2.0mm 1.5mm

4. Optical AssemblyUse a blower brush; if dirt cannot be removed, use alcohol:(1) No. 1, 2, 3 mirror; (2) dust-proofing glass; (3) original reflecting plate;(4) standard white plate.

5. Optical Path(1) Scanner Cable

Check the cable for tension; as needed, make adjustments.(2) Cable Rail

Clean the slides, and lubricate with silicone oil (FY9-6011).6. Waste Toner Colleting Container

If the waste toner collecting container is more than half full, dispose of the toner in aplastic bag; or, replace the toner collecting container itself.

1. Be sure to observe all rules and regulations of the governing communitywhen disposing of waste toner.

2. Do not dispose of waste toner into fire. (It may explode, causing a sig-nificant hazard.)

7. Clean the copyboard glass and the reader glass.8. Make test copies.9. Make sample copies.



1-8T

10. Check the operation of the leakage breaker.With the power switch at ON, press the test switch of the leakage breaker to see thatthe breaker operates normally (i.e., the lever goes OFF to shut off the power).If the breaker fails to operate normally, replace it, and make a check once again.Resetting:

After making a check, shift the power switch to OFF, lever to ON, and then thepower switch to ON.

11. Put the sample copies into order, and clean up the area around the machine.12. Record the most recent counter reading.13. Fill out the Service Record, and report to the person in charge.

Be sure to indicate the results of the check you have made on the leakage breaker.

1 Making Initial Checks1.1 Site Environment

Be sure of the following:a. The voltage of the power supply is as rated (10%). The power plug remains connected

throughout day and night.b. The site is not a high temperature/humidity environment (near a water faucet, water

boiler, humidifier), and it is not in a cold place. The machine is not near a source of fireor dust.

c. The site is not subject to ammonium gas.d. The site is not exposed to direct rays of the sun. (Otherwise, provide curtains.)e. The site is well ventilated, and the floor keeps the machine level.f. The machines power plug remains connected to the power outlet.

1.2 Checking the Papera. The paper is of a recommended type.b. The paper is not moist. Try paper fresh out of package.

1.3 Checking the Placement of Papera. Check the cassette and the manual feed tray to see if the paper is not in excess of a spe-

cific level.b. If a transparency is used, check to make sure that it is placed in the correct orientation in

the manual feed tray.

1.4 Checking the DurablesCheck the table of durables to see if any has reached the end of its life.

1.5 Checking the Periodically Replaced PartsCheck the scheduled servicing table and the periodically replaced parts table, and replace

any part that has reached the time of replacement.



3-2T

1.6 Checking the Units and Functional Blocks[Reader Unit] Check the optical system (mirror, while plate, copyboard glass, reflecting plate) for dam-

age and foreign matter. Check the mirror base to see that it moves smoothly and its rail is free of dirt. Check the scanning lamp to see it is free of flickering. Check the scanner cable to see that it is correctly routed. Check the scanner to see that it is free of condensation.

[Process System] Check to see that the toner container contains toner. Check to see that the drum unit is properly fitted. Check the photosensitive drum to see that it is free of damage and dirt. Check the window of the SALT sensor to see if it is free of dirt.

[Transfer System] Check the secondary transfer unit to see that it is free of foreign matter. Check the ITB/secondary transfer external roller for wear, scratches, dirt, and deforma-

tion. Check the blade of the ITB cleaning unit for tear, peeling, deformation, and stray toner.

[Fixing System] Check the fixing roller/pressure roller for wear, tear, and deformation. Check the fixing heater (main/sub) to see that it operates when power is turned on. Check the fixing thermistor to see that it is free of an open circuit. Check the thermal switch to see that there is electrical continuity.

[Paper Feeding System] Check to see if there is residual paper or other foreign matter. Check to see if there is a buildup of paper lint on the pickup, feeding, and separation roll-

ers. Check the rollers for wear, tear, dirt, and deformation. Check the pre-registration roller, registration roller (upper/lower), and paper path roller

for wear, tear, and dirt, and deformation. Check the feeding guide for wear, tear, dirt, and deformation. Check the paper for a bent leading edge, curling, waving, and absorption of moisture. Check the paper and/or transparency to see if it is a recommended type. If not, try a rec-

ommended type to see if the symptom in question still occurs.



3-3T

[Mechanical System] Check to see if the load of the drive system is excessive. Check the gears for wear and tear (chipping).

[Cassettes] Check to see if the cassettes are properly fitted. Check to see if the paper size is correctly

set. Try replacing with a normal cassette to see if the symptom in question still occurs. Check to see that the holding plate of the cassette moves smoothly and that it is free of

deformation. Check to see that the side guide plate and the rear guide plate of the cassette are fitted cor-

rectly. Check to see if the switch of the cassette heater is turned on (if the machine is equipped

with a cassette heater).

[Service Mode] Check to see if the various CCD adjustment values are as indicated on the service label.

(COPIER>ADJUST>CCD>all items) Check to see if the machine executes registration adjustment.

(COPIER>ADJUST>FEED-ADJ>REGIST/ADJ-REFE) Check to see if the machine correctly detects the internal temperature/humidity.

(COPIER>DISPLAY>ANALOG>TEMP/ABS-HUM) Check to see if the image read position is correctly adjusted.

(COPIER>ADJUST>ADJ-XY>ADJ-X/ADJ-Y/ADJ-Z) Check to see if the paper reference value data is correct.

(COPIER>FUNCTION>CST-ADJ) Check to see that the value of ADJUST/OPTION is as indicated on the service label. Check to see if error clear has been initialized.

(COPIER>FUNCTION>CLEAR>ERR)

[General] Is the power plug properly connected? Is the rated AC voltage present at the power outlet? Are the sensors, clutches, motors, and solenoids operating normally? Are the connectors

free of poor contact?(Be sure to check the routes of power and signals by referring to the general circuit dia-gram.)

Has the leakage breaker or the circuit breaker gone ON? Is there biting of a wire or a loose screw? Are all eternal covers attached properly?



3-4T

Are the main power switch and the control panel power switch ON? Are the power cable and the signal cable to all accessories routed correctly? Does the cover switch operate normally? Is the fuse on each PCB blown? Is the user aware of the correct use of the machine?

1.7 OthersIf a machine is brought from a cold to warm place, condensation can occur inside it, lead-

ing to various problems:a. condensation on the BD sensor can cause problems associated with E110.b. condensation on the LDE lens can cause image in sub scanning direction to be too light.c. condensation on the mirror of the reader unit or on the copyboard glass can cause im-

ages to be too light.d. condensation on the pickup or feeder guide can cause paper feeding faults.

If any of the foregoing (a through c) occurs, use the following service mode to correct it(Chapter 5 Service Mode of Troubleshooting):

COPIER>FUNCTION>INSTALL>DRY-RTUse it to eliminate condensation at time of installation work.

If d has occurred, dry wipe the pickup and feeder units.

Moreover, the toner container and the drum unit can also develop condensation if it isbrought in from a cold to warm place (unpacked). To prevent condensation, advise the userto leave them alone for 1 to 2 hours before unpacking them at the site.

As necessary after installation, use the following service mode (Chapter 5 ServiceMode of Troubleshooting):

COPIER>OPTION>BODY>SLPOFF01 to SLPOFF12Use it to disable sleep mode.
