LCD Display and Indicators
LCD Display This two line by sixteen-character display is used
to convey several types of information. When the
printer is on line and printing, or ready to print,
the display will show the currently selected
tractor path and the form currently loaded in that
path. When the printer is off line, the display will
continue to show this information, additional
information based upon other buttons being
pressed by the operator, or error conditions such
as “Check Paper”.
POWER This green LED indicates that the printer is
plugged into a power source, the power switch is
on, and the internal power supply is functional.
ONLINE This green LED indicates that the printer is ready
to receive printable characters and/or commands
from the host computer, and print or perform as
requested.
FAULT This red LED indicates that the printer has
detected an error condition, such as paper out,
paper jam, or an internal diagnostic error. Many
internal diagnostics are performed each time the
printer is turned on or reset, and some continue
to monitor operation during printing.
SETUP
This yellow LED indicates that the setup mode
has been entered.
BELL The printer sounds a tone when it is directed to
do so by a bell character (BEL) from the host
computer. Other tones also alert operators of
error conditions, such as paper out, and indicate
when buttons are pressed.
