The status indicator light is located on the feed button indicating the status of the GX and GK Series printers. Regardless of the color, the status indicator light appears whenever the printer is turned on.
The symptoms addressed by this solution include:

  •  Solid Green Light 
  •  Solid Red Light 
  •  Solid Amber Light (Orange) 

Refer to the printer status indicator from the table below:

Error 1 The LED is off - The printer is not receiving power.

  • Did you power on the printer?
  • Check the printer’s power connections from the wall outlet to the power supply, and from the power supply to the printer.
  • Disconnect the printer from the wall outlet for 30 seconds and then reconnect the printer to the wall outlet. 

Error 2  Solid Green - The printer is powered on and in idle status.

  • No action is necessary.

Error 3  Solid Amber - The printer has failed its Power-On Self-Test (POST).

Error 3  Solid Amber - There is a memory error.

  • If this error occurs after printing, turn the printer's power off and on, and then resume printing. 

Error 3  Solid Amber - The printhead needs to cool down.
