3.3 Logic Board and Bottom Cover Replacement Cautions

3.3.1 Logic board replacement cautions

The various settings, waste ink amount, and other data stored in the logic board's
EEPROM cannot be rewritten into the new EEPROM after the logic board is replaced.
The data in the new logic board's EEPROM is not set. After the logic board/EEPROM is
replaced, reset the EEPROM as described in
When replacing the logic board, visually check the amount of waste ink in the waste
ink absorber. Replace the bottom cover if necessary. Depending on the amount of
waste ink already absorbed, ink may leak even before a waste ink-full error warning
appears.
However, it is not necessary to replace it if the printer has been used for less than 2
weeks and less than 50 pages have been printed out.

3.3.2 Cautions after replacing the bottom cover

After a waste ink-full error occurs and the bottom cover are replaced, reset the
EEPROM.
NOTE
Figure 5-2 Bottom Cover
When a waste ink-full error occurs, it can be assumed that the printer has
printed more sheets than its service life called for. However, this depends on
how many times the cartridge has been replaced and the usage conditions.
When a color BJ cartridge is used, more ink is consumed due to head
maintenance as compared to a black BJ cartridge. Therefore, the waste
ink amount will also be more.
