4.1.5 EEPROM Reset Procedure

Like other EPSON ink jet printers, this printer is equipped with an EEPROM on the main board. This

EEPROM stores status information and ink system management parameters. Since the ink system status is

unique to each printer mechanism (and the printhead or ink cartridge installed), the information stored in the

EEPROM must be consistent with the printer mechanism actually connected to that board. This section

providesthe procedures to maintain the consistency ofthe ink status during repair of theprinter.

Table 4-3. EEPROM Operation

Service Performed Operation Required

After replacing the C199 MAINboard.

❒If the printerstill works:

Refer to Section 4.1.5.1

❒If the printerdoes not work:

Refer to Section 4.1.5.2

After replacing the ink cartridgewith a new one

(without encountering an InkEnd Error). Refer to 4.1.5.3

After replacing the waste ink pad

(without encountering a MaintenanceError). Refer to 4.1.5.4

After replacing the printheadwith a new one. Refer to4.1.5.3

Printer indicates a MaintenanceError. Refer to4.1.5.4

4.1.5.1 Writing Data to the EEPROM

If the main board needs to be replaced (even if it still works correctly), you need to print out all the data

stored in the current EEPROM and write and save the settings to the EEPROM on the new board. This is

particularly important to maintain consistency in the status information stored in the EEPROM and the actual

status of theprinter mechanism.

1. Run adjustment programCLR200.EXE, and select EEPROM Data Manipulation from the main

menu.

2. Choose EEPROM DATA DUMP from thesub menu. The printer prints a dump of thedata stored in the

EEPROM.

3. When thedump print is complete, choose EEPROM DATA RESTORE from the sub menu andinput

alldata printed out. If an EEPROM address is shown on thePC as “—-,” it is a reserved address and no

data inputis necessary.

❒After completing the operation above, perfrom the Bi-D Alignment and Zig-Zag adjustments.
