TROUBLESHOOTING

CHAPTER

EPSON Stylus Photo R220/R230 Revision A

1.1 Overview

This chapter describes how to identify troubles in two levels: unit level repair and component level repair. Refer to the flowchart in this chapter to identify the defective unit and perform component level repair if necessary. This chapter also explains motor coil resistance, sensor specification and error indication.

Since CR Motor and APG Motor are DC Motors, the resistance among the electric poles varies. Therefore, judge if it is normal or abnormal based on if there is no operation of the motor or not; the resistance values cannot be used to judge the abnormality. However, it is difficult to judge accurately, if it is not clear, replace the motor.

1. The Ink Cartridge has run out of ink.

2. The Ink Cartridge is faulty.

(Note) Even after Ink Out Error is detected, a small amount of ink remains in the Ink Cartridge to protect the Print Head from printing operation.

This error is detected when the ink consumption reached 90%.

(Note) When the Ink Low Condition is detected, the Error Reset LED is blink. The blinking continues until the cartridge is replaced with a new one and the Carriage Unit returns to the home position.

1.3 Unit Level Troubleshooting

You can identify the troubles by using the checklist in this section after confirming the LED 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 "DISASSEMBLY/ASSEMBLY" and replace them. The following tables describe the error conditions (LED and STM3) and their possible cause.

(Note) When individual part that makes up the Roller EJ Assy., the PF Motor and the 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 "DISASSEMBLY/ASSEMBLY."
