Table 5.2.1a. Control Panel LEDs
Glows to show that an Error/Fault has occurred and operator intervention is
required in order to allow printing to continue.
When On Line, this LED flashes to indicate that data are being processed by
either Postscript, PCL, PJL, or is being spooled to the disk. If data are not being
processed, or either Postscript or PCL is processing a job but waiting for data
(input buffer empty), this LED is Off.
When the LED flashes, data are being received by one of the emulation (i.e.,
Postscript, PCL, or PJL). When a secure or proof job is sent to the printer, this
LED flashes while the job is being received, even though data are not being
processed or printed.
This LED also flashes during processing of spooled jobs when one of the
emulations processes a job and the input is filled from the disk rather than from
one of the host interfaces.
