3.1 Overview

This chapter describes how to solve problems.
W A R N I N G
To avoid electric shocks, be careful when checking the electrical
circuit boards below while the power is on.
Touching an FET, transistor or heat sink with one hand while
touching a metal part of the mechanism with the other hand could result in an electric shock, so carefully avoid this.
After initial filling of ink has been repeated several times,
immediate moving or tilting of the printer could result in leaking of ink that has not been completely absorbed by the Waste Ink Pad. When initial filling of ink has been repeated several times, check the ink remaining in the tip of the Waste Ink Tube and the waste ink not absorbed by the Waste Ink Pad before moving the printer.

P O I N T
Disassembly and reassembly of parts is often required when
identifying the causes of problems. The parts should be disassembled and re-assembled correctly while referring to
“DISASSEMBLY/ASSEMBLY” (p.80) so that the operation
and status of each check item can be correctly verified.
Some individual part and units may require adjustment once
they are removed or replaced. If removing or replacing parts which have specific instructions for adjustment included in
“DISASSEMBLY/ASSEMBLY” (p.80), be sure to make these
adjustments after repairing the problem location.
In this chapter, the product names are called as follows:
Basically, description in this chapter is based on WorkForce
