Resetting to Factory Defaults

You can restore default values by performing a cold reset on your

printer (see your printer documentation for instructions).

O To perform a cold reset on some older HP LaserJet printers,

turn

off the printer and then press and hold the Go, Start, or

Pause/Resume button as you turn the printer back on.

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

MFPs, you must interrupt the printer’s power-on sequence to

enter the printer service menu, and then select Cold Reset.

A document that describes how to perform a cold reset on many

printers is available on HP’s Web site. To view the document,

visit HP online support at:

http://www.hp.com/go/support

and search for document file hpj02300.html.

CAUTION A cold reset restores both your printer and

Jetdirect configuration to their factory

default values.

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.
