CHAPTER 1 MAINTENANCE AND INSPECTION

3 Periodical Ser vicing Procedure

1. As a rule, provide periodical servicing every 120,000 prints.

2. Before setting out on a scheduled visit, check the Service Book, and take any parts that may require replacement.

As of June 2001

Work Procedure

1. Report to the person in charge, and check the general condition.

2. Record the counter reading, and check the faulty prints.

3. Make test prints, and check them for the following: (1) image density, (2) w hite background for soiling, (3) characters for clarity, (4) margin, (5) fixing, registration, and back for soiling. The margin must meet the following standards:

Leading edge: 2.5 ± 1.5 mm Left edge: 2.5 ± 1.5 mm Right edge: 0.5 mm or more Trailing edge: 2.5 +1.1, -1.7 mm (smaller than B4) <2.5 ± 2.0 mm>

3.5 +0.6, -2.8 mm (B4 or larger) <3.5 ± 2.0 mm>

5.5 +1.5, -5.0 mm (free size) < >: when the DADF-H1 picks up an original

(in stream readig mode).

4. Optical Unit Clean the following using a blower brush to clean; if the dirt is excessive, use alcohol: (1) No. 1/2/3 mirror, (2) original illuminating reflecting plate, (3) lens, (4) original size

sensor.

5. Scanner Drive System (1) Scanner cable; check the tension, and adjust as necessary. Inspect and adjust the scan-

ner cable only when the machine has made the first 250,000 prints.

(2) Scanner rail; clean the slide area, and apply silicone oil (FY9-6011).

CHAPTER 1 MAINTENANCE AND INSPECTION

6. Feeding System Clean the following: (1) feeding assembly base, (2) fixing inlet guide (upper, lower), (3) transfer guide, (4) pre-registration assembly (paper lint).

7. Image Formation System Clean the following: developing member, (2) developing assembly bottom.

8. Optical Unit Clean the following with a special tool: (1) bending mirror.

9. Image Formation System Inspect and, as necessary, remove the waste toner and then clean the waste toner case; or, replace the waste toner case if any:

1. Be sure to dispose of the water toner according to the standards imposed by the government concerned.

2. Do not dispose of waste toner into fire (to avoid explosion).

10. Make test copies.

11. Make sample copies.

12. Check the operation of the leakage breaker. While the power switch is ON, press the test switch of the leakage breaker to make sure that it operates normally (i.e., the lever goes OFF to cut the power). If the leakage breaker fails to operate normally, replace it and make a check once again. To reset, After making a check, turn off the main power switch (the lever should go ON), and then turn on the main power switch.

13. Put the sample copies into order, and clean up the area around the machine.

14. Fill out the Service Book, and report to the person in charge; put a description of the check made on the operation of the leakage breaker in the Service Book.

CHAPTER 1 MAINTENANCE AND INSPECTION

6 Cleaning the Bottom of the Developing Assembly

If the bottom of the developing assembly is not cleaned thoroughly, the residual toner can soil the back and the leading edge or left/right edges of prints. If soiling is noted, clean also the transfer guide and the static eliminator at the same time as the bottom of the developing assembly.

6.1 Cleaning the Bottom of the Developing Assembly

1) Open the front door.

2) Slide out the developing assembly [1].

3) Dry wipe the bottom of the developing

assembly.

4) Slide in the developing assembly.

5) Close the front door.
