49.XXXX
PRINTER ERROR
alternates with
To continue
turn off then on
A critical firmware error has occurred
that caused the processor on the
formatter to abort operation. This type
of error can be caused by invalid print
commands, corrupt data, or invalid
operations. In some cases, electrical
noise in the cable can corrupt data
during transmission to the printer.
Other causes include poor quality
parallel cables, poor connections, or
home-grown applications. On rare
occasions, the formatter is at fault,
which is usually indicated by a
79 Service Error.

Stop to clear the print job from the
