Preface

This chapter describes disassembly and reassembly procedures of the printer.

The service technician is to identify the cause of printer failures according to follow the disassembly procedures of each part to

replace the defective parts or the consumable parts.

Note the following precautions when working on the printer.

• Before disassembling or reassembling the printer, be sure to disconnect its power cord from the electrical outlet.

• When having removed the Drum Unit from the host machine before disassembling and assembling the machine, be sure to

put the Photosensitive Drum in a protective bag even in a short period of time to prevent the adverse effect of light.

• Reassembling procedures are followed by the reverse of disassembly unless otherwise specified.

• Note the length, diameters, and locations of screws as you remove them. When reassembling the printer, be sure to use

them in their original locations.

• Do not run the printer with any parts removed as a general rule.

• Ground yourself by touching the metal part of the printer before handling the PCB to reduce the possibility of damage caused

by static electricity.

• When you replace the part that the rating plate or the product code label is attached, be sure to remove the rating plate or

the product code label and put it to the new part.

For reduction in weight, thin plates are used in some parts of this machine.

In the case of a screw hole with a triangle mark near it as shown in the figure below, strongly tightening the screw may damage

or deform the screw hole.

In the case of a screw hole with a triangle mark, carefully tighten the screw, taking care not to apply too much force.

The recommended torque value is shown below as a reference value.
