The Indicator Lights The Control Panel contains four indicator lights. Table1.1
describes the function of each light.
Table 1.1 Indicator lights and their functions
Light Description
Online (Green) Lights when the printer is online.
Flashes when the printer is transitioning from online to offline or
to indicate that a print job is being processed.
Form Feed (Green) Lights when the printer experiences a form feed timeout—that is,
when a PCL job has formatted a partial page, the printer is
waiting for more data in order to continue processing the job,
and a 15 second timeout period has expired with no new data
arriving in the input buffer. This timeout applies to all ports.
When lit, you can print a partial page by entering the Job menu,
scrolling to the Form Feed item and pressing Enter. When not in
the menu system, a partial page can be printed by pressing Enter.
PostScript does not print partial pages and consequently the
Form Feed light is not turned on.
Fault (Amber) Lights whenever operator intervention is required in order to
allow printing to continue.
Data (Green) Flashes to indicate that a print job is being received and/or
processed by either PostScript, PCL or PJL. In the case of proof or
secure jobs, the print job is received but is not processed until the
required password is entered at the Control Panel, at which time
the indicator flashes to indicate processing.
