LCD. The LCD serves two purposes: displaying current image processor and
print engine status information and displaying an interactive menu. Status
information includes image processor status such as
Ready
,
Receiving data
and
Printing

Out of paper
,
Paper Jam

Add ink
.
The interactive menu can only be entered while the printer is idle and ready.
The interactive menu has two modes, review and modify. Customers can review
and modify certain NVRAM, I/O ports and peripheral parameters. Using the
front panel to review and change parameters is discussed in Chapter 9 “Check
and Adjustments.”
Buttons.
Button 1, the left-most button, is an Exit key used to cancel an operation
while in the interactive menu. The functions of buttons 2, 3 and 4 are defined by
the particular menu or function being displayed on the LCD. The bottom row of
the LCD labels the current function of each button. The topic “NVRAM” on
page 9-36 explains how to use the front panel buttons to reset the NVRAM to its
factory default values.
