The control panel
The control panel consists of eight labeled keys. These keys navigate the menu
system for printer operations. Two LEDs on the display indicate On Line and
active faults. The LCD display is two lines by twenty-four characters wide.
Key 0 places the printer off-line or on-line. Key 4 is an Enter key. The pairs of
keys 1 and 5 are used to scroll through the main menu. Keys 2 and 6 navigate the
sub menus, and Keys 3 and 7 scroll sub-menu values. Key 6 cancels print jobs.
On Line LED
Green in color, this LED indicates when the printer is “On Line” and ready to
process data. When transitioning from “On Line” to “Off Line”, the LED flashes
at a rate of two times per second. When data is being received and processed, the
LED flashes at a rate of once per second.
! Fault
Red in color, this LED illuminates whenever operator intervention is required,
such as a paper jam in the printer.
