Paper Cutter Error:
Error Description | Power | Error | Recovery Conditions |
Paper Cutter Error | OFF | Flashes at .125 second intervals | Recovered by turning OFF, removing the paper jam or affected area, returning the cutter to the home position and turning ON |

NOTE: When an unrecoverable error happens, you can turn off and back on to see if the error goes away. You may also want to try another power source as well. However, if the error continues, you will need to turn off the printer and contact the person you purchased the hardware from, or the manufacturer.
