computer.
Note: Non-IEEE-approved printer signal cables might cause unpredictable problems.
1. Any device drivers and other software that came with the printer are correctly installed.
2. You have assigned the printer port correctly in your operating system, application program, or BIOS
settings. For more information about BIOS settings, see Chapter 7 "Using the Setup Utility program"

Serial connector problems

Use this information to troubleshoot the serial connector and devices attached to the serial connector.

grounded electrical outlet.

• If the serial device has an Online switch, make sure that it is in the Online position.
• If the serial device is a printer, make sure that paper is loaded correctly.
• Verify that any software supplied with the serial device is correctly installed. Refer to the documentation
for the serial-device option.
• Make sure that the serial-connector adapter, if you added one, is properly installed and firmly seated.
