Table 6. General Symptom List
11. Load paper. Power on the printer. Press PAPER
ADVANCE and VIEW several times and check that paper
moves in both directions. Replace the paper feed motor if
paper does not move in both directions.
12. Power on the printer. Press PAPER ADVANCE and VIEW
several times and check that paper moves in both
directions. Replace the controller board if paper does not
move in both directions.
1. Remove the paper path or pedestal top cover. Reseat all
cable connections to the controller board and the power
supply board.
2. Power on the printer. If the printer "hangs," replace the
controller board.
3. Power on the printer. If the printer "hangs," replace the
power supply board.
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 on 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 on 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 on the printer. Send a print job from the host. If the
printer still does not print from the host, replace the
controller board.
