network connections. For best
performance, we recommend that you use
a Category 5 100Base-TX Ehternet cable.

computer and reconfigure any that are not
correct.

driver for your operating system is

the printer driver.
Is the printer’s IP address correct? (When
using TCP/IP.)
Call your system administrator to obtain a
valid IP address. Use the printer
configuration list to confirm the IP address.
