Printer Troubleshooting

There are a few possibilities as to why your printer may suddenly stop working as intended:

1. Printer is not printing
   • The thermal receipt paper roll has run out.
   • The printer cover is not fully or properly closed, check for error messages.
   • Device is on airplane mode, causing the printer to be disconnected.
2. Printer is printing, but the receipt is blank
   • Thermal paper may be inserted on the wrong side.
   • Paper roll used is not thermal paper.
3. I am unable to open my printer cover
   • Check that the printer knife is not revealed causing a blockage, this is usually caused by prematurely pulling out the receipt before the machine cuts it.
