Chapter 2: Operator Panel

Using the Operator Panel

This chapter describes the NEC SuperScript
Operator panel and its functions.
The Operator panel consists of four LEDs and
the Operator panel button.
• The On Line LED (green) usually
indicates normal operation (warming-up,
ready, or Energy Saving Mode).
• The Paper LED (amber) usually indicates
that the printer needs paper.
• The Manual Feed LED (amber) usually
indicates that the printer is ready for manual
feed.
• The Error LED (red) indicates printer
errors such as "cover open" or "paper size
error."
• The Operator panel button lets you resume
operation after correcting a problem (such as
adding more paper or closing the cover). You
can also use the button to print a Settings
page, exit Energy Saving Mode, or reset the
printer to factory defaults.

LED Operation

When the printer is first turned on, all LEDs
light immediately and then cycle in sequence.
26
The blinking lights indicate that the printer is
initializing and performing an internal test. When
the printer is ready to accept a job, the green On
Line LED stays steadily lit. From the ready state,
pressing the Operator panel button for four
seconds and releasing it activates the initialization
(reset) and internal test. The LEDs will cycle on
until the printer is reset. Once the printer is reset
the LEDs will return to their ready state (green
LED steadily lit).
Table 2-1 provides a prioritized list of printer
problems with LED status, condition, cause, and
solution.
