The LED in combination with the beeper indicates the nature of 3 kinds of errors: fatal, error, and warning.

Fatal Error: The ERROR indicator and POWER indicator blink at the same time. The number of beeper sounds indicates the type of error.
Error: The ERROR indicator and POWER indicator light. The number of beeper sounds indicates the type of error.
Warning: The ERROR indicator blinks and the POWER indicator lights. The number of beeper sounds indicates the type of error.

* Ink Low warning is enabled only when the ink low warning selection is set to on. The default setting is on.
Recoverable errors by customer:
1) Paper pick-up error:
Occurs when the paper cannot be fed properly.
2) Paper jam:
Occurs when the printed paper cannot be ejected.
3) BJ Cartridge check:
Occurs when a BJ cartridge Is not installed and the cartridge replacement mode is terminated by the printer. This error is recovered once it enters the cartridge replacement mode by holding down the CARTRIDGE button.
4) Cartridge mis-match error:
Occurs when the data in the host computer does not match with that of the installed cartridge. This error is recovered by holding down the CARTRIDGE button and installing the correct cartridge.
Unrecoverable errors by the customer:
5) ROM error:
Occurs when the ROM check during the initializing operation fails.
6) RAM error
Occurs when the RAM check during the initializing operation fails.
7) EEPROM error:
Occurs when the EEPROM checking function fails during every process. (eg. initialization, printing. etc...)
8) Home Position error:
Occurs when the home position cannot be detected.
9) Waste ink full error:
Occurs when the "total waste ink amount? recorded on the EEPROM exceeds the prescribed limit.
10) temperature error:
Occurs when the temperature sensor ITH 1) on the control board is defective.
11) Abnormal temperature rise error:
Occurs when the diode sensor on a BJ cartridge head detects the temperature to be above a predetermined value.
12) Diode sensor error:
Occurs when the diode sensor on a BJ cartridge head Is defective.
13) No head Installation error:
Occurs when the printer cannot detect the BJ cartridge other than during the cartridge replacement operation.
14) Print position detection error:
Occurs during when the home position cannot be detected during the print position detection process.
15) Low battery error:
Occurs when the DC input voltage is less than a predetermined value.
