Paper Feed Error; Paper Jam Error; Ink Out Error; No Bj Cartridge Error - Canon BJC6500 - BJC 6500 Color Inkjet Printer Service Manual

BJC-6500
Description of Error Indications
Errors recoverable by users:

1) Paper feed error

Paper feed operation fails to feed paper.

2) Paper jam error

Paper eject operation of 23 inches fails to eject the paper.

3) Ink out error

The indicated ink tank is out of ink (ink chamber and sponge).
4) BJ Cartridge mis-installed error
The BJ cartridges are not installed in their correct positions.

5) No BJ cartridge error

One or both of the BJ cartridges are not installed.
The scanner cartridge is installed in the color (right) cartridge side.
6) BJ Cartridge error
One or both of the BJ cartridges are defective (unreadable ID, or out-of-range
rank).
7) Waste ink warning
The amount (stored in EEPROM) of waste ink absorbed is at 95% of the defined
capacity.

8) Head position adjustment error

The automatic head position adjustment has failed.
Errors unrecoverable by users:

9) ROM error

ROM checking during initialization is NG.

10) RAM error

RAM checking during initialization is NG.

11) EEPROM error

Writing to EEPROM has failed.

12) Home position error

The home position sensor is defective (broken circuit) or fails to detect home
position.
13) Temperature sensor error
The thermal sensor (TH1) on the logic board is defective (broken circuit).

14) Waste ink full error

The amount (stored in EEPROM) of waste ink absorbed is at 100% of the defined
capacity.

15) Head temperature error

The inside temperature of the BJ cartridge is too high. This error should occur
earlier than the head temperature sensor error.

16) Head temperature sensor error

The thermal sensor in the BJ cartridge is defective.

17) Cartridge displaced error

The printer cannot detect the BJ cartridge when the carriage is out of the cartridge
replacement position.
18) ASF sensor error
The pick-up roller doesn't turn during paper feeding, or the pick-up roller doesn't
detect the pick-up roller's flag.
19) Ink sensor error
During the ink sensor check at initialization, it will be reported that there is ink,
even when there is none. Ink checking is only performed at power-on during
initialization, and it will be reported that there is ink. As this error is not displayed,
it can be checked on the EEPROM information printout in the error history section.
