CHAPTER 3 THE MECHANICAL SYSTEM This chapter describes mechanical operation as well as disassembly and reassembly procedures of the printer. Note the following precautions during disassembly or reassembly. 1. When you remove the EP cartridge, cover the cartridge with a cloth or put it in a dark place to prevent light from affecting the drum inside the cartridge. 2. Remove the cartridge from the printer before disassembling or transporting the printer. 3. CAUTION: Before servicing the printer, disconnect its power cord from the electrical outlet. 4. Assembly is the reverse of disassembly unless otherwise specified. 5. Note the lengths, diameters, and locations of screws as you remove them. When reassembling the printer, be sure to use them in their original locations. 6. Do not operate the printer with any parts removed. 7. Discharge electrical static from your body by touching the metal frame of the printer prior to installing the PCB in order to avoid causing damage by the difference in static charge at that time. I.
