A network reset changes all network system parameters in NVRAM to the factory defaults. During
the network-reset process, all button presses are ignored.

Use the following procedure to perform a network reset.

Turn off the printer.

Press and hold the 

Job Cancel

 button.

Turn on the printer and continue to hold the 

Job Cancel

 button for approximately 10 seconds,

but no longer than 20 seconds. During this process, the 

Attention

 light turns on.

Release the 

Job Cancel

 button. The 

Attention

,

Ready

, and 

Go

 lights begin cycling from front to

back. After the network-reset process is complete, the device returns to the ready state.

If the 

Attention

 and 

Ready

 lights illuminate before you release the 

Job Cancel

button, start again at step 1.

A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike
NVRAM initialization, a cold reset does not reset the page count, the paper tray sizes, language, or
formatter number.

A cold reset also resets all the HP Jetdirect settings as well as the printer settings.

Use the following procedure to perform a cold reset.

Turn off the printer.

Press and hold the 

Go

 button.

Turn the printer on, and continue to hold the 

Go

 button for at least 5 seconds, but not longer

than 15 seconds. During this process, the Attention LED turns on.

Release the 

Go

 button.

If both the Attention and the Ready LEDs turn on before you release the 

Go

button, you must start the procedure again with step 1.

The printer's LEDs begin cycling. The cold-reset process runs until completion, and the printer
returns to the ready state.
