If a system error message indicates a port problem or if equipment connected to a port seems to perform

incorrectly or not at all, the source of the problem may be any of the following:

A faulty connection between the I/O port and the peripheral device

A faulty cable between the I/O port and the peripheral device

A faulty peripheral device

Incorrect settings in the System Setup program

Incorrect settings in the system's configuration files

Faulty I/O port logic on the system board

NOTE: With certain modems installed, the Serial/Infrared Port Test Group subtests may fail

2. Insert the Dell ResourceCD into the appropriate drive, reboot the system, and run the Serial/Infrared

Ports Test Group and/or the Parallel Ports Test Group in the Dell Diagnostics.

If any of the tests fail, the system board may be faulty. See " Getting Help" for instructions on obtaining

Device," depending on which device appears to be malfunctioning.

1. Reinstall the printer device driver.

See the documentation for the printer and for your operating system for instructions on reinstalling the

printer driver.

2. Turn off the parallel printer and computer, replace the parallel printer interface cable with a known
