CHAPTER IV TROUBLESHOOTING AND

ERROR MESSAGE

This section gives the service personnel some of the troubleshooting procedures to

be followed if an error or malfunction occurs with this machine.
It is difficult to anticipate all of the possible troubles which may occur in future and

determine the troubleshooting procedures, so this chapter covers some sample

troubles.
However, those samples will help service personnel to identify other defective

elements and repair them if he/she analyzes and examines this chapter carefully.

4.1

PRECAUTIONS

Be sure to observe the following precautions to prevent the secondary problems from

happening during troubleshooting.
(1) Make sure to unplug an AC cord to ensure no power supply, when doing

conductivity test with a tester.

(2) When printing error occurs, pull out the thermal head cable from the connecter

until the peripheral circuit related to the thermal head works properly.

4.2

AFTER REPAIRING

Verify again that the repaired portion works properly. Then adjust and examine this

machine according to

“APPENDIX 1 SERVICEMAN SOFTWARE TOOL (Version 1.00)”

It is recommended to record and store actual troubleshooting and repair procedures

to accumulate repair know-how.
