This chapter describes mechanical features and operations as well as disassembly and assembly pro-
cedures.
The following precautions must be observed during disassembly and assembly work.
1.
For the sake of safety, disconnect the power plug before performing any disassembly or assem-
bly work.
2. Unless otherwise specified, assembly work is performed in the reverse order of the disassembly oper-
ations.
3. Be sure to use the right type (diameter and length) or screws in the right places.
4. An inner-clip washer is used with one securing screw in the metal cover to prevent buildup of static
electricity. Make sure to use this washer during assembly work.
5. In principal, the copier must not be operated when parts have been removed.
