5. Insert your System Software CD into the CD-ROM drive, reboot the computer,
and run the Serial Ports device group and/or the Parallel Ports device group in
the Dell Diagnostics. (See “Running the Dell Diagnostics” found later in this
chapter.)
The Serial Ports device group and the Parallel Ports device group check the
basic functions of the system board’s I/O port logic. Also, if a parallel printer is
connected to the parallel port, the Parallel Ports device group tests the
communication link between the system board’s I/O port logic and the printer.
Do the tests complete successfully?
Yes. Go to step 6.
No. Call Dell for technical assistance. (See Chapter 5, “Getting Help,” for
instructions.)
6. If the problem persists, go to “Troubleshooting a Parallel Printer” or
“Troubleshooting a Serial I/O Device” found later in this chapter.

2. Swap the parallel printer’s interface cable with a known working cable.
3. Turn on the parallel printer and computer.
4. Attempt a print operation on the parallel printer.

No. Go to step 5.
5. Run the parallel printer’s self-test.
Does the self-test complete successfully?

No. The printer is probably defective. If you bought the printer from Dell, call Dell
for technical assistance. (See Chapter 5, “Getting Help,” for instructions.) If you
purchased the printer elsewhere, take it to one of the manufacturer’s authorized
service centers for repair.
