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.
