BJC-6000 Part 5: Maintenance 5.2 Adjustment/ Setting Procedures 5.2.1 EEPROM setting The EEPROM (IC602) on the control board stores total amount of waste ink absorbed, function settings, and other information specific to the printer. If you have replaced the control board, you must initialize the EEPROM of the new control board and change its data as necessary. Since the content of the EEPROM of a replacement control board is not defined, you must always initialize the new EEPROM before use. For the initializing procedure, refer to Part 3: 3.6.1 Service mode operations (page 3-18). If you have replaced the control board, you must visually check the waste ink absorber for ink level and replace it if necessary. If the waste ink level is considerably high but the waste ink absorber was not replaced, the waste ink could leak before the printer issues the waste ink full warning. There is no way to write the total amount of waste ink absorbed, function settings, and other printer-specific information as stored in the old EEPROM into the new EEPROM. The total amount of waste ink absorbed may be reset to 0% but not to any other value. When you have replaced the waste ink absorber, you must clear the waste ink counter of the EEPROM or initialize the EEPROM. For the procedures, refer to Part 3: 3.6.1 Service mode operations (page 3-18). NOTE The waste ink full error should not normally occur before the printer's designed life expires (as counted by printed sheets). The error may occur, however, if the printer has been switched on and off very often, the BJ cartridges have been replaced very often, or the printer has been used in unfavorable conditions. 5.2.2 Carriage belt tension adjustment When the carriage belt has been loosened to replace the carriage, or for other reasons, the tension of the carriage belt must be readjusted. Insert the tension spring (QY90043-000) in the correct position to adjust the belt tension, and fix the pulley assembly by tightening the fixing screws, and then remove the tension spring.

5.2 Adjustment/ Setting Procedures
5.2.1 EEPROM setting
The EEPROM (IC602) on the control board stores total amount of waste ink absorbed,
function settings, and other information specific to the printer.
If you have replaced
the control board, you must initialize the EEPROM of the new control board and
change its data as necessary.
Since the content of the EEPROM of a replacement
control board is not defined, you must always initialize the new EEPROM before use.
For the initializing procedure, refer to
Part 3: 3.6.1 Service mode
operations (
page 3-18)
.
If you have replaced the control board, you must visually check the waste ink
absorber for ink level and replace it if necessary.
If the waste ink level is considerably
high but the waste ink absorber was not replaced, the waste ink could leak before the
printer issues the waste ink full warning.
There is no way to write the total amount of waste ink absorbed, function settings,
and other printer-specific information as stored in the old EEPROM into the new
EEPROM.
The total amount of waste ink absorbed may be reset to 0% but not to any
other value.
When you have replaced the waste ink absorber, you must clear the waste ink
counter of the EEPROM or initialize the EEPROM.
For the procedures, refer to
Part 3:
3.6.1 Service mode
operations (page 3-18)
.
The waste ink full error should not normally occur before the printer's
designed life expires (as counted by printed sheets).
The error may occur,
however, if the printer has been switched on and off very often, the BJ
cartridges have been replaced very often, or the printer has been used in
unfavorable conditions.
5.2.2 Carriage belt tension adjustment
When the carriage belt has been loosened to replace the carriage, or for other reasons,
the tension of the carriage belt must be readjusted.
Insert the tension spring (QY9-
0043-000) in the correct position to adjust the belt tension, and fix the pulley
assembly by tightening the fixing screws, and then remove the tension spring.
