3. NOTES ON SERVICING
3.1 EEPROM Data
The printer keeps track of the total sheets printed by each BJ cartridge configuration
(Black/Color and Photo/Color) and the total waste ink amount and stores that
information in the EEPROM (IC 602) on the logic board. Observe the following
precautions during servicing:
1) Before servicing
You can check the EEPROM data with a test print. The total sheets printed by each
configuration can provide important information on how much the printer has been
used.
2) If the control board (EEPROM) is replaced (or if stored data is cleared by
mistake)
Check the waste ink absorber, and replace it with a new one if necessary. If you fail
to replace the waste ink absorber in time, the waste ink full alarm might not be
issued in time and waste ink could leak (depending on the current ink absorbing
capacity of the waste ink absorber). When replacing the logic board (EEPROM) with
a new one, be sure to clear the data on the new EEPROM, because the data is not
defined.
3) After the waste ink absorber is replaced
After replacing the waste ink absorber, as prompted by the waste ink full alarm,
clear the data on the EEPROM.
CAUTION
REF.
Once cleared, the EEPROM data cannot be restored (cannot be checked
with a test print). Always check the EEPROM data with a test print before
clearing it. The data includes information on the user settings, the total
sheets of printed paper and the total amount of waste ink absorbed. Note
that you cannot edit the data from the operator panel.
The printer calculates the total amount of waste ink absorbed based on
the estimated usage of the printer. To prevent the capacity of the waste
ink absorber from being exceeded, the waste ink full alarm is issued when
the waste ink absorber gets full, suspending the operation of the printer.
Refer to Part 3: 3.6.4 Resetting EEPROM (Page 3-21) for the procedures for
checking the EEPROM data with a test print or for clearing the data.
Refer to Part 5: 6. TROUBLESHOOTING (Page 5-13) for the troubleshooting
procedures to be followed when the waste ink full alarm is issued.
