Solving Printer Problems
If you experience problems printing, run a printer self-test. Refer to the
documentation provided with your printer for instructions. If the
self-test fails, it is a printer-specific problem. Also refer to the
printing section of your application documentation.

Solving Screen Problems
This section lists some common causes and solutions for computer display
and external monitor problems.
IMPORTANT: Verify that the display jumpers on the processor board are set
properly for the display before proceeding with any
troubleshooting.
You can perform a monitor self-test on an external VGA color or monochrome
monitor by disconnecting the monitor from the computer. To do so, complete
the following steps:
1. Turn off the monitor.
2. Turn off the computer.
3. Disconnect the monitor signal cable from the computer.
4. Turn on the monitor and allow it to warm up for one minute.
The screen should be white. A narrow black border may also appear on
the left and right sides of the display. Either of these displays
indicates that the monitor is working properly.
