The pages that follow contain instructions on how to disassemble and assemble the machine. Be sure to follow the instructions whenever you have to replace parts
to correct a fault or at the end of the part life.
All work must be performed with the following in mind:
1. The instructions assume that the cassettes and cartridges have already been removed. Whenever you have removed a cartridge from the machine, make sure it is
in a protective bag to limit its exposure to light (no matter how short it may be).
2. The power plug must be disconnected for safety before starting to disassemble or assemble the machine.
3. Unless otherwise indicated, assembly is the reverse of disassembly in terms of the sequence of steps to perform.
4. The screws and fixings must be identified correctly in terms of type (length, diameter) and location.
5. The machine must not be operated with any of its parts removed.
6. You must not touch any PCB without first discharging the build-up of static electricity from your body, as by touching a metal area of the machine.
7. You must not touch the following with bare hands: pickup roller, separation pad, ETB, photosensitive drum, fixing film, pressure roller.
