3.4.4 Setting the EEPROM
After replacing the control board or waste-ink absorber, reset the EEPROM, set the model settings, and
do a test printout to confirm the settings.
The EEPROM (IC502) on the control board stores various printer data such as the waste-ink amount and
other printer specific settings.
The procedure is described in 7.1 Service Mode Operations on page 2-28 .
(1) After control board replacement
If the waste-ink absorption amount is over 7 percent at the time you replace the control board, also
replace the waste-ink absorber. Then reset the EEPROM and restore the printer settings.
To check the waste-ink absorption amount, you can either check the service/factory text printout from
the old control board or visually check the waste-ink absorber's waste-ink absorption amount.
Also, the new control board (EEPROM) data is undefined.
The EEPROM must be reset. Otherwise, the waste-ink full error will not occur, even when the waste-
ink absorber's capacity has been exceeded, thereby leaking ink.
(2) After waste-ink absorber replacement
Clear the EEPROM's waste-ink counter.
Once the data in the EEPROM is reset, a test printout cannot be used to confirm the old
data. Be sure to print the data before resetting the EEPROM.
The various settings (except the model setting), sheet count, and waste-ink amount will be
reset.
The various settings and waste-ink amount stored in the old EEPROM cannot be written to
the new (replacement) EEPROM.
The waste-ink full error is expected to occur only when the printer prints more than the
number of sheets specified for its service life. However, how soon this error occurs varies
depending on how many times the printer has been turned on/off, the number of times the
BJ cartridge has been replaced (front cover open/closing), and the operating environment.
3.4.5 Adjusting the carriage belt tension
If the carriage belt tension has been loosened to remove the carriage, etc., adjust the carriage belt tension.
When securing the pulley assembly, use the tension spring (QY9-0043) and tighten the screws. After
tightening the screws, remove the tension spring.
