Service Menu Example

To perform a cold reset on many recent HP LaserJet printers and MFPs:

1.Turn the printer on and watch for the memory count to begin.

2.Press and hold the Select button (or the “6” button on MFPs with numeric keypads only) until the three control panel lights (Ready, Data, Attention) blink and then remain on.

3.Release the Select button (or “6” button). The control panel will display Select Language.

4.Press the down arrow button (or “9” button) until Cold Reset appears.

5.Press the Select button (or “6” button) to perform a cold reset and then continue the power-on sequence.

Controlling Network Protocols

The HP Jetdirect print server can simultaneously support multiple network communication protocols. This allows network computers that may be using different protocols to communicate with the same printer.

Each protocol used on the print server may require some configuration before the printer can communicate on the network. For some protocols, required parameters are automatically sensed and user-specified settings are not needed. However, for other protocols, there may be many parameters to configure.

Enable or Disable Network Protocols

By factory default, only the TCP/IP network protocol is enabled.

If a network protocol is enabled, the card may actively transmit on the network even when there are no computers on the network that use the protocol. This may 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, IPX/SPX).

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

display protocol-specific error conditions for enabled protocols only.

To disable unused protocols through the device’s control panel menu, see HP Jetdirect EIO Control Panel Menus on page 21. For other tools, such as Web browser access to the embedded Web server, or system command access to the embedded Telnet server, see the HP Jetdirect Print Servers Administrator’s Guide for your print server model.
