002
Replace the system board.
003
On keyboards with a detachable cable, replace the cable.
If the problem remains or if the cable is permanently
attached to the keyboard, replace the keyboard. If the
problem remains, replace the system board.
Printer
1. Make sure the printer is properly connected and
powered on.
2. Run the printer self-test.
If the printer self-test does not run correctly, the problem is
in the printer. Refer to the printer service manual.
If the printer self-test runs correctly, install a wrap plug in
the parallel port and run the diagnostic tests to determine
which FRU failed.
If the diagnostic tests (with the wrap plug installed) do not
detect a failure, replace the printer cable. If that does not
correct the problem, replace the system board or adapter
connected to the printer cable.
