ERROR indications, the control panel only changes when the error

You can pause printing with the Go button. Pressing the Go button
again restarts the print job and clears the pause. During a pause, the
printer is off-line.
If the printer is in PAUSE mode and you do not want to print
the remaining data, you can cancel the job by pressing the
Job Cancel button. Once the job has been cancelled the
printer will return to the READY state.
