How to fix Casio UP-400 Printer if it won't turn on?
- C
  Crystal StevensAug 3, 2025
  If your Casio printer won't turn on, first ensure the power switch is in the ON position. Then, check that the power adapter is firmly connected. If the printer resets when you turn it on, there may be an issue with the operation panel. Also, verify that the LED on the adapter lights up when connected to the wall; if not, check the power supply cord or the adapter itself. It could also be a problem with the power switch parts or the main board.

  If your Casio printer is printing garbled output or failing to print from the host, start by running a self-test to assess print capability. If the self-test fails, consult the 'Can’t Print' section. Ensure the interface connector is securely connected with screws. Finally, verify the DIP switch settings by referring to the Appendix, correct any errors, and then power cycle the printer.

  If the ERROR indicator is illuminated on your Casio printer, check whether the printer is out of paper and replace the roll if needed. If the cover won’t open even when you slide the cover open knob, the Automatic Paper Cutter might be locked; refer to section 3.3, “Printer Jam”. If the printer cover doesn’t close completely, open it by sliding the cover open knob and then close it again by pushing at the center of the cover.

  If the drawer kick isn't working on your Casio printer, first, ensure the drawer kick is properly connected; re-plug the cable until you hear or feel a click. Next, check the Y-cable to verify it's connected in the correct order. If these steps don't resolve the issue, there may be a problem with the main board inside the printer.

  If the ERROR indicator doesn’t light up on your Casio printer while paper is exhausted and the printer cover is closed, and the ON LINE Indicator lights up by using the ON LINE button, there may be something wrong with the paper sensor of the main board inside the printer. Alternatively, there could be an issue with the operating panel.
