Eeprom Reset; Printing The Eeprom Data - Canon BJC-1000 Service Manual

BJC-1000

2.4 EEPROM Reset

The EEPROM records various settings, the data on the total number of sheets printed,
and the total waste ink absorption amount for the color and black ink cartridges
respectively. The total number of sheets printed and the total waste ink absorption
amount can serve as a reference for how much the printer has been used.
The EEPROM must be reset when the logic board or the bottom cover is replaced.
See Part 5: 3.3 Logic Board and Bottom Cover Replacement Cautions (page 5-4) , for details.
2.4.1 EEPROM Reset
"Waste ink full" is detected with the total waste ink absorption amount recorded in the
EEPROM. When the ink absorber is replaced, the data on the total waste ink
absorption amount in the EEPROM must be reset. Furthermore, when the logic
board is replaced, the new logic board's EEPROM must be reset and the waste ink
absorber must be also replaced at the same time. To reset the EEPROM, follow the
procedure below.
1. Without the cartridge installed, connect the plug of the AC adapter to the AC outlet
while holding down the RESUME button.
2. Release the RESUME button. Press it down again within five seconds and release it.
3. Hold down the RESUME button for two seconds or more and release it.
4. Set EEPROM by pressing the RESUME button as shown in the table below.
