Troubleshooting
IO Configuration page
The IO Configuration page provides comprehensive print server status. It is an important diagnostic tool,
especially if network communications are not available. For a description of messages that may appear on
the IO Configuration page, see the HP Jetdirect Print Servers Administrator’s Guide for your print server
model.
LEDs
The printer has status lights (LEDs) that indicate the link status and network activity.
● When the green light is on, the printer has successfully linked to the network.
● When the yellow light is blinking, there is network transmission activity.
Link troubleshooting
If the printer does not successfully connect to the network:
● Both LEDs will be off.
● LAN Error - Loss of Carrier will be indicated on the IO Configuration page.
If a link failure is indicated, try the following:
● Check cable connections.
● Manually configure the link setting to match the port configuration of the network hub or switch. For
manual configuration methods, see
Link configuration methods on page 38 . Turn the printer off, then
on again, to re-initialize the setting.
● Print an IO Configuration page and check link settings.
