JOB IN PROCESS
When the printer is receiving data or processing data, JOB IN
PROCESS flashes. If data has been processed and is waiting to be
printed, or has been printed but not yet fused and ejected by the
printer, JOB IN PROCESS lights continuously.
JOB IN PROCESS does not light when the printer is not processing
data, no data exists in the buffer, and the printer is not receiving
data.

command, and while the printer is unavailable for printing due to its
normal system activities, such as booting, printing its configuration,
writing status information, and loading applications.
IMPORTANT Do not press any control panel key when STAND BY is
flashing. The printer may carry out unwanted commands.

printer is ready to print and accept data from the host). It flashes
when the printer is offline or when the printer stops because of an
error.
FAULT
FAULT flashes when the printer is unavailable for printing because
of an internal error.
