BJC-50
Recoverable errors by customer:
1) Paper pick-up error:
Occurs when the paper cannot be fed properly.
2) Paper delivery error:
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.
5) No battery error:
Occurs when the lithium ion battery is not installed in the printer. This error is
recovered by unplugging and re-plugging the DC jack of the Universal adapter once
the lithium ion battery is installed.
6) Failed battery warning:
Occurs when the printer detects a battery voltage lower than 7V. The printer begins
to recharge the battery to bring up the voltage above 7V, however, if the voltage does
not rise above 7V after 90 minutes, recharging is stopped. (At this point, the printer
may still be operated with an Universal adapter.) Also occurs when the reserve
recharging current is lower than a certain set value while the battery is recharging.
Recharging is stopped. (There is a problem with either the recharging circuit or the
battery itself.) This warning is recovered by removing the faulty battery and replacing
it with a new one.
Unrecoverable errors by the customer:
7) ROM error:
Occurs when the ROM check during the initializing operation fails.
8) RAM error:
Occurs when the RAM check during the initializing operation fails.
9) EEPROM error:
Occurs when the EEPROM checking function fails during every process.
(eg. initialization, printing, etc...)
10) Home Position error:
Occurs when the home position cannot be detected.
11) Waste ink full error:
Occurs when the "total waste ink amount" recorded on the EEPROM exceeds the
prescribed limit.
12) Internal temperature error:
Occurs when the temperature sensor (TH1) on the control board is defective.
13) Abnormal temperature rise error:
Occurs when the diode sensor on a BJ cartridge head detects the internal
temperature to be above a predetermined value.
14) No BJ head error:
Occurs when the printer cannot detect the BJ cartridge other than during the
cartridge replacement operation.
