Network Diagnostics Overview
This test routine is intended to be used to provide an automated method to check
the network configuration of the printer. When the test is initiated through the
Control Panel, it will be able to provide an error indicator with suggested resolution
for the user.
Diagnostic Status Returned
• Function status - OK (0) if no error is found
• Integer error code - 0 (success - no error), #1 (internal error), #2 thru n [as
defined in the Error Codes Returned table] (errors found)
• Pointer to a character string corresponding to the error code returned.

connector?
Is the network cable plugged into the printer and a known working
network port?
Try swapping the network cable. If no success, Reset NVRAM and
retest.

separating the printer via a network switch.

may be set to the wrong mode.
Use the Control Panel to switch Ethernet speed full/half duplex and
retest. (Printer Setup -> Connection Setup -> Network Setup ->
Ethernet speed)

Setup - > Connection Setup -> Network Setup -> TCP/IP Setup ->
TCP/IP On)

(If DHCP enabled, no server responded yet. so wait 1 minute for
AutoIP and retest. If DHCP disabled, no server will respond and the
address needs to be entered manually or reset NVRAM and reboot
the printer.)
