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 poorquality
parallel cables, poor connections, or
specific software programs.
Sometimes, the formatter itself is at fault,
which is usually indicated by a 79 Service
Error.

1 Press CANCEL JOB to clear the print job
from the printer memory.
2 Turn the printer off and then on.
3 Go to www.hp.com/go/lj4350_software.
Select Download Drivers and
Software. Check for the latest firmware
image version at the bottom of the
page. If this firmware image is newer
than the one installed on the printer
and the printer can receive a firmware
update, download the newer firmware
upgrade.
4 Try printing a job from a different
software program. If the job prints, go
back to the first program and try
printing a different file. If the message
appears only with a certain software
program or print job, contact the
software vendor for assistance.
5 If the message persists when using
different software programs and
attempting specific print jobs,
disconnect all cables that connect the
printer to the network or a computer.
6 Turn the printer off.
7 Remove all memory DIMMs or thirdparty
DIMMs from the printer. (Do not
remove the firmware DIMM in slot J1.)
See Firmware DIMM (LJ 4200/4300
only).
8 Remove all of the EIO devices from the
printer.
