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".
