This table lists information about the symptoms, possible causes, and remedies for problems that can occur
with the printing system (combination of the print controller and copier). It is intended to help engineers find
information as quickly as possible, and provide basic solutions.

Troubleshooting of the print controller and 7022/7130/7135 copiers
Symptoms Causes Actions
[Printer basic mode] screen does
not appear on the copier's dis-
play after main power-on. No power supply to the print controller. Check if the print controller is connected
with the copier properly.
"Warming up" does not disap-
pear. Copier is in trouble. Locate the cause of trouble of the
copier.
"Initialization" does not disappear
on the copier screen. The print controller has not started prop-
erly. See the column of "Print controller does
not start".
Printout is defective, or nothing
can be printed. The system board or some boards of
the copier are defective. Put the copier in 36 mode and perform
test. If it operates properly, system
board may be failure.
Print controller does not start. The system board is inactive. Check the connector of the controller
board. Replace the system board as
necessary.
Software of the print controller is
destroyed. Reinstall the software of the print con-
troller.
Test print can be produced but
not from the parallel port. The parallel port has something wrong
or the cable is wrong or, the problem is
on the computer side. Check the cables (internal/external).
Perform test using a data generator or a
well-proven PC/I/O cable. Replace the
system board as necessary.
With the standard printer lan-
guage PCL, correct outputs are
produced, but with PostScript3
even PS Demo Page cannot be
printed out at all. PostScript3 Protection Chip not cor-
rectly installed. Reinsert PostScript3 Protect Chip. If the
problem still occurs, replace PostScript3
Protect Chip with a new one.
Test print can be produced but
not from the network port. The network controller is inactive or not
installed properly. Examine the network controller. Check
all connectors. Replace the system
board as necessary.
Test print can be produced and
all ports are good, but user jobs
cannot be printed. Some software error has happened. Print controller's software or application
program has something wrong. Save
the file, which failed to be printed, in the
disk and analyze the problem by suit-
able means.
