1.3 Unit Level Troubleshooting

You can identify the troubles by using the check list in th is sect ion after conf ir ming t he

LED/LCD indication on the con trol panel or the error message displayed on STM3 of

the PC connected to the printer. As a result, you can save the whole repair time. When

finding any faulty parts, refer to Chapter 2 "ASSEMBLY/DISASSEMBLY" and

replace them. Following tables describe the error conditions (LED/LCD and STM3)

and their possible cause.

The following is the example of how to use the tables.

Example) When "Carriage Unit" is out of the home position at the power on timing,

the Fatal Error may be caused by the failure of "CR Motor". Moreover,

there are 3 possible causes on "CR Motor" failure.

(Note)

When individual part that makes up "Roller EJ Assy.", "PF Moto r" and "In k System

Assy." is defective, replace the Printer Mechanism with a new one basically. However,

if an individual part needs to be replaced urgently, execute the necessary operation by

referring to Chapter 2 "ASS E MBL Y/DISASSEMBLY".
