TROUBLESHOOTING Unit Level Troubleshooting 14
1.3 Unit Level Troubleshooting
You can identify the troubles by using the checklist in this section after confirming the
LED/LCD indication on the control 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 Motor" and "Ink 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 "ASSEMBLY/DISASSEMBLY".

When turning on the power, the
initialization is performed correctly.
However, a Communication Error is
displayed on STM3 even transferring the
printing job to the printer.

on "Main Board".
1. Write proper Market Setting in the Adjustment
Program.
USB Cable
1. Check if "USB Cable" is connected properly between
the printer and the PC.
