Lexmark 5770 manual Disabling bidirectional communications

Troubleshooting

•The parallel port on your computer is not configured for bidirectional communications.

•The IRQ (Interrupt Request) assigned to your printer is also assigned to another hardware device, such as a scanner or sound card. This situation is commonly called a "hardware configuration conflict."

Contact your computer manufacturer, or see the documentation that came with your computer to determine if your computer supports bidirectional communications.

With bidirectional communications problems you can use your printer, but the printer software will not function to its fullest capability. You can change printer settings, send print jobs to the printer, and change and align print cartridges. However, printer status and ink level information will not display on your computer screen.

On most computer systems, the parallel port configuration and IRQ assignments are changed from the computer's Configuration or Setup Utility. Check the documentation that came with your computer for information on the Configuration or Setup Utility.

Warning! If you are not familiar with configuring parallel ports or changing IRQ assignments, do not change these settings in the Setup or Configuration Utility. Contact your computer manufacturer or an experienced computer professional for assistance.

Incorrect changes to your computer's configuration can cause serious problems.

Disabling bidirectional communications

If you cannot solve the bidirectional communication problem immediately, you can disable bidirectional communications. This does not solve the bidirectional communications problem but allows you to print jobs without an error message appearing.
