Printer does not print from the
host
1. Check the host data cable connection at the rear of the
printer. Attach the data cable to the printer interface.
2. Make a configuration printout. Verify that the printer
matches host interface settings. Set printer interface
parameters to match those of the host.
3. Power up the printer. Send a print job from the host. If
printer does not print and the interface is RS-232,
interchange the wires to pins 2 and 3. (This is the most
common cause of an inoperative RS-232 cable.) Verify
that the host and printer have the same baud rate, number
of data bits, number of stop bits, and parity. Configure the
host for XON/XOFF if possible, since this requires the
least complex cable.
4. Power up the printer. Send a print job from the host. If the
printer does not print from the host, replace the data and
interface cable assemblies.
5. Remove the paper path or pedestal top cover. Check all
cable connections on the controller board. Reseat all cable
connectors on the controller board.
6. Power up the printer. Send a print job from the host. If the
printer still does not print from the host, replace the
controller board.
Printer does not print self
tests
1. Power off the printer. Remove the paper path or pedestal
top cover. Disconnect the control panel cable from
connector J110 on the controller board. Disconnect the
control panel cable from the control panel. Check
continuity of the control panel cable assembly. Replace
the control panel cable assembly if it fails continuity test.
2. Connect the control panel cable assembly to J110 on the
controller board and to the control panel. Load paper.
Power on the printer. Run a self test. If the self test does
not run, replace the control panel assembly.
3. Power on the printer. Run a self test. If the self test does
not run, replace the controller board.
