The Control Panel contains four indicator lights. Table 3.3 
describes the function of each light.

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 
processed by either PostScript, PCL or PJL, 
or is being spooled to the optional hard 
disk (e.g., a proof or secure job).
