BJC-6000 Part 3: Operating Instructions 3.2 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 still 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. 6) BJ cartridge error One or both of the BJ cartridges are defective. 7) Waste ink warning The calculated (and stored in EEPROM) amount of waste ink absorbed has reached 95% of the defined absorbing capacity. 8) Auto head 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 otherwise fails to detect home position. 13) Temperature sensor error The thermal sensor (TH201) on the logic board is defective (broken circuit). 14) Waste ink full error The calculated (and stored in EEPROM) amount of waste ink absorbed has reached the 100% of defined absorbing 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) Ink sensor error Ink sensor checking during initialization is NG. If this error occurs, no indication is made, but the printer will not check ink level and assumes that the level is normal until the printer is switched off. You can confirm the error by printing the EEPROM information. 19) Pump sensor error Pump sensor checking during initialization is NG. No indication is made for this error, but it can be confirmed by printing the EEPROM information. 3-13
