49.XXXX
PRINTER ERROR
To continue turn off then on
A critical firmware error has occurred that
caused the processor on the formatter to
abort the operation.
This type of error can be caused by invalid
print commands, corrupt data, or invalid
operations.
In some instances, electrical noise in the
cable can corrupt data during transmission
to the printer. Other causes include poor-
quality parallel cables, poor connections, or
specific software programs.
Sometimes, the formatter itself is at fault,
which is usually indicated by a 79 Service
Error.
After performing the actions above,
procede with the following:
1 Turn the printer on.
2 If the error message disappears,
reinstall each DIMM and EIO device
individually, making sure to turn the
printer power off and then on again as
you install each device. To replace
a DIMM, see Firmware DIMM
(LJ 4200/4300 only).
3 Replace the DIMM or EIO device that
caused the error message.
4 Remember to reconnect all of the
cables that connect the printer to the
network or computer.
5 If this error message persists, replace
the firmware DIMM. See
Firmware
DIMM (LJ 4200/4300 only).
6 Replace the formatter assembly. See
Formatter assembly .
