HP 400N manual Enabling and Disabling Network Protocols, To restore configuration default values

Enabling and Disabling Network Protocols

When you first install the card from the factory, all supported network protocols are enabled (or turned on) when you turn the printer on. The card provides automatic network switching between network protocols for printers that do not support this function. If you reconfigure the card—for example, you disable a network protocol—your configuration is saved on the card and is maintained even after the printer is turned off.

If a network protocol is enabled, the card may actively transmit even when the protocol is not in use on the network. This may slightly increase network traffic. To eliminate unnecessary traffic, you can disable unused protocols. Disabling unused protocols lets you:

•reduce network traffic by eliminating broadcast messages from unused protocols (for example, NetWare and TCP/IP).

•provide better control over who prints to the printer by eliminating users from other networks who might accidentally route print jobs to this printer.

•eliminate unnecessary information on the self-test page or configuration plot, which displays status information for all enabled protocols.

•display protocol-specific error conditions on the printer control panel. These warning messages are displayed only if all enabled protocols are unable to print.

To restore configuration default values

You can restore default values by performing a cold reset on your printer. To perform a cold reset, turn off the printer and then hold down [On Line] (or [Go] on some printers) as you turn the printer back on. This restores your printer configuration to the factory default values.
