3.1 Overview

This chapter describes how to solve problems.

3.1.2 Preliminary Checks

Before starting troubleshooting, be sure to verify that the following conditions are all met:

WARNING „

„

„

Be careful to avoid electric shocks when checking the electrical circuit boards (MAIN and PSE/PSB boards) while the power is turned 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.

† The power supply voltage must be within the specification limits. (Measure the

voltage at the wall socket.)

† The power code must be free from damage, short circuit or breakage, or miswiring

in the power code.

† The printer must be grounded properly.

† The printer should not be located in a place where it can be exposed to too high or

low temperature, too high or low humidity, or abrupt temperature change.

† The printer should not be located near waterworks, near humidifiers, near heaters

or near flames, in a dusty atmosphere or in a place where the printer can be

exposed to blast from an air conditioner.

† The printer should not be located in a place where volatile or inflammable gases

are produced.

identifying the causes of problems. The parts should be

 

disassembled and re-assembled correctly while referring to

 

“DISASSEMBLY/ASSEMBLY” (p.54) 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.54), be sure to make these adjustments after repairing the problem location.

3.1.1Specified Tools

This printer does not require any specified tools for troubleshooting.

† The printer should not be located in a place where it can be exposed to direct rays

of the sun.

† The printer must be placed on a strong and steady level table (without an

inclination larger than five degrees).

† Any vibrating equipment must not be placed on or under the printer.

† The paper used must conform to the specification.

† There is no error in handling of the printer.

† Check the inside of the printer, and remove foreign matters if any, such as paper

clips, staples, bits of paper, paper dust or toner.

† Clean the inside of the printer and the rubber rolls.
