CHAPTER 3

MECHANICAL SYSTEM

To disassemble/assemble the Printer, following the instructions given in this chapter. The service

person is expected to identify the cause of a fault by referring to the descriptions in Chapter 4

‘Troubleshooting,’ and then to replace appropriate parts according to the instructions given while

heeding the following:

1. Before dissembling/assembling or moving the Printer, take out the toner cartridge if neces-

sary. If removed, it must always be kept in a protective bag or covered with paper to protect the

photosensitive drum from the effects of light (if for a short time).

Disconnect the power plug for disassembly/assembly work.

3. Unless otherwise noted, reverse the steps used to disassemble when assembling the Printer.

4. Identify the screws by type (length, diameter) and location.

5. As a rule, do not operate the Printer with any of its parts removed.

6. When handling a PCB, be sure to touch a metal area of the Printer to be free of static charges,

thereby preventing damage to the PCB.

7. Do not touch the rubber portion of the pickup roller or the transfer charging roller with bare

hands.

8. Take full care when disconnecting the flat cable. When connecting it, be sure to keep it straight,

never fitting it at an angle.
