Troubleshooting
Infrared Port Problems Action
An infrared device does
not work. Verify that:
1. No serial device is assigned to serial port B.
2. The infrared port is enabled and is assigned a
unique address.
3. The infrared transceiver is properly installed.
4. The infrared device drivers have been properly
installed.
5. Nothing is blocking the infrared transceiver.
If the items above are correct, have the system serviced.
Printer Problems
Action
The printer does not
work. Verify that:
1. The printer is turned on and is online.
2. The printer signal cable is connected to the correct
serial or parallel-port on the system. (For the
location of the serial or parallel port, see
“Input/Output Connectors” on page 9.)
Note: Non-IBM printer cables might cause
unpredictable problems.
3. You have assigned the printer port correctly in
your operating system or application program.
4. You have assigned the printer port correctly using
the configuration programs.
If the items above are correct and the printer still does
not work, run the tests described in the documentation
that comes with your printer. If the tests show the
printer is OK, have the system serviced.
