Message Description Action
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.
