I. Preface - Canon LBP-800 Service Manual

I. PREFACE

This chapter describes the disassembly and reassembly procedures of the printer.
The service technician is to identify the factor of malfunction according to the "Chapter 4
Troubleshooting" and to replace the defective part(s) following the disassembly procedure of each
part.
Note the following precautions when working on the printer.
1. Remove the toner cartridge when disassembling, reassembling, or transporting the printer.
Removed cartridge must be put in the protective bag to prevent the adverse effect of light.
2. CAUTION: Before servicing the printer, disconnect its power cord from the electri-
cal outlet.
3. Assembly is the reverse of disassembly unless otherwise specified.
4. Note the lengths, diameters, and locations of screws as you remove them. When reassem-
bling the printer, be sure to use them in their original locations.
5. Do not operate the printer with any parts removed.
6. 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.
7. Do not place the printer with the drive unit or the laser scanner unit at the bottom.
