TION

[1] Scope and Precautions

This section provides detailed information about the adjustment items and procedures. Before addressing customer complaints, perform the following checks:

1. Check whether the power supply voltage meets the specifications.

2. Check whether the power supply is properly grounded.

3. Check whether this machine shares the power supply with any other machine that draws large current intermittently (e.g., elevator and air conditioner that produce electrical noise).

4. Check whether the installation environment is good.

a. The machine must be installed in a properly ven-

tilated area not exposed to high temperature, high humidity, and direct sunlight.

b. The machine must be installed on the horizontal

floor.

5. Check whether original has a problem to cause the defective image.

6. Check whether the selected density value is correct.

7. Check whether the surface of the platen glass and the slit glass are clean.

8. Check whether correct paper is used for copying.

9. Check whether copying materials and parts (e.g., developer, drum, and cleaning blade) are replenished and replaced when they reach the end of the useful life.

10. Check whether toner remains.

When servicing the machine, observe the following precautions:

1. Only either side of the AC line is shut off when the SW1 (main) of this machine is turned off. Always unplug the power cord before starting the service work. If it is necessary to service the machine with the power on, take care not to be caught in the scanning gear of the exposure unit.

2. Special care should be taken when handling the fixing unit because it operates at extremely high temperatures.

3. The developing unit has a strong magnetic field. Keep watches and measuring equipment away from it.

4. Take care not to damage the drum with tools and so on.

5. Do not touch IC pins with bare hands.

WHEN REPLACING PARTS

Adjustments (including checks) and settings are not only required when a customer complaint about the copy image quality is received, but also after replacing or reassembling parts.

[1] How to Read Tables

Components of the tables used in this section are as follows:

1. Mode

Adjustment mode to be selected. [P]: Utility mode [25]: 25 mode [36]: 36 mode [47]: 47 mode

2. Code

Code and copy quantity setting button used in each mode.

3. Page

Page in the "ADJUSTMENT" section.

4. Circled numbers

Indicate that adjustments (including

checks) must be made in order of precedence.

(Circle without numeric character):

Indicates that adjustments (including checks) can be made independently.

Caution: Replacing the image control board

• When a damaged image control board is replaced, the memory board on this board must be used on the new image control board. Only when the memory board is damaged, use a new memory board. Since the new memory board does not have adjustment data, the above adjustments are required. Before making the above adjustments, make the “47-92(output)” setting to make the new memory board effective.

• After making any adjustment, make the “47mode-96(output) setting”. After made the “47mode-96(output)” setting, the adjustment data is saved.

• However, the “47mode -92” and -96" settings are protected to prevent them from careless operation. In order to make “47mode -92” and -96" settings using the saved adjustment data, the protection must be disabled. For the unprotection method, contact the service section of the authorized distributor.

This bit is used to keep the cleaning blade off the drum to protect the drum and cleaning blade during transportation of the main body. To keep the blade off the drum, set this DIP switch to 1, open the front door to turn OFF the interlock, and start up the 47 mode. The blade switching operation is performed at this time. If blade 1 is used, do not forget blade charge and 36 mode blade set mode at reinstallation. This DIPSW will be reset to 0 automatically.

When copying the original which black ratio is low (less than 1 %), gray background image is caused because the toner density of developer increases. In this case, changing this bit to 1, decreases the amount of toner supplied regularly, thus preventing gray background image.

This paper has only little difference in paper quality between the front and the back side, and has much strength.

(2) Paper for printing books

This paper has lower paper density than highquality paper. Cream color is often used as a suitable color for books.

Intermittent copy mode

In this mode, the machine goes into the copy ready state after completing a set number of copy operation, waits 0.5 sec., and then repeats the same operation.

Paperless running mode

In this mode, the machine makes copies at approximately the same timing as for normal copy without performing paper detection or jam detection. In addition, similar to intermittent copy mode, the machine goes into the copy ready state after completing a set number of copy operation, waits 0.5 sec., and then repeats the same operation.

Paperless mode

In this mode, the machine makes copies at approximately the same timing as for normal copy without performing paper detection or jam detection.

Paperless endless mode

In this mode, the copy quantity is set to infinity. In addition, similar to Paperless mode, the machine makes copies at approximately the same timing as for normal copy without performing paper detection or jam detection.
