CAUSE/SOLUTION
This occurs when processing with the Multi-purpose tray or 500-
Sheet cassette is empty.
Corrective Action: Load paper into the tray.
The on line LED blinks while the printer is processing a job from
your computer or while finishing printer warm-up and initializa-
tion. This includes waiting for the computer to send additional
data or waiting for the printer engine to move paper. Pressing the
Operator panel button causes the printer to pause printing. The
printer's memory cache can accept and process data during warm-
up time.
The LED blinks slowly while the printer is in Energy Saving Mode.
Energy Saving Mode starts after the printer has been ready as
long as specified by the Energy Saving Mode setting. The printer
exits Energy Saving Mode when it receives a job, or the Operator
panel button is pressed.
PCL data left in the printer.
Corrective Action: Pressing the Operator panel button will
cause a form feed then resume to ready.
