BJC-3000

2.4 Resetting the EEPROM

The EEPROM records various settings, the data on the total number of sheets passed
with the Black/Color/Photo BJ cartridges and Scanner cartridge, the total waste ink
amount, and data on the last three user-unrecoverable errors. The printer detects
"waste ink full" with the total waste ink amount recorded in the EEPROM. When the
waste ink absorber is replaced, the data for the total waste ink amount must be reset.
Also, when the control board is replaced, the EEPROM of the new control board must
be reset and the waste ink absorber replaced.

2.5 Model Settings with EEPROM

The control board of this printer is used in common with other models of Canon
printers. When the control board is replaced, the initial data must be set to correspond
with the machine.
After setting the model, perform the service/factory test print to confirm the settings.

2.6 Ink Presence Check

The printer will scan the carriage to detect the amount of ink remaining in the ink tank,
and print the result. The operation of the ink sensor can be verified with this function.
1) Install an empty ink tank into the BJ cartridge.
2) Using the Ink Presence Check function, printout the result.
3) Confirm that the value of "ExistInk" is "0" for the ink tank that is empty.

2.7 Power Off/Carriage Lock

The printer will move the carriage to the home position, lock the carriage, and turn
itself off, regardless of the presence/absence of a BJ cartridge in the carriage.
