The most common errors consist of Paper Out, Low Battery, and Head
Jam. The other errors listed are of rare occurrences, but are provided for
good printer diagnostics in the event failures should occur.
Power-On Self-Test (POST)
When the printer is reset, it performs a POST to verify other reasons the
printer might be failing. Audible error codes, along with indicator light
status, are produced during POST if an error is encountered, as listed in
the
POST Error Codes
table.
A printer diagnostic cable, connected between the host computer and the
printer, is used during POST to: configure the printer, access printer diag-
nostics, update software, and install new fonts.
To install the diagnostic cable: connect the phone plug into the phone jack
on the printer, then connect the 9-pin DSub plug into the host computer.
After installing the diagnostic cable, reset the printer to initiate POST.
POST Errors
POST errors only occur after a push button reset, or an initial application
of power to the printer. After the reset button is pressed, the LEDs (on the
printer control panel) indicate the progress of POST. The first LED to
light should be the power indicator (Green LED). A single beep should be
heard immediately after this LED lights up to indicate the printer is active.
