Network reset 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. 1. Turn off the printer. 2. Press and hold the Job Cancel button. 3. 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. 4. 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. NOTE If the Attention and Ready lights illuminate before you release the Job Cancel button, start again at step 1. Cold reset 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. NOTE 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. 1. Turn off the printer. 2. Press and hold the Go button. 3. 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. 4. Release the Go button. NOTE 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. 178 Chapter 7 Problem solving ENWW
