How can I reset the nvm on a pyronix enforcer

Have a look at the following link:

http://www.enxmag.com/2013_months/aug2013/WorkCentre7425StyleFaultCodeList_82013.htm

It has a list of fault codes and also tells you how to reset NVM counts. Look in the bottom right of the page for the instructions. Hope this helps.

Try this:

If you have set an admin password for CWIS (CenterWare Internet Services - your webGUI) then this procedure should reset that password.

1. Press the Menu button on the control panel.
2. Select Admin Menu
3. Select Network Setup
4. Select Reset Defaults

The other reset procedure is going to initialize all of the machine's NVM (Non Volatile Memory). Note: this procedure, and the one above, will not roll back the f/w on your machine.

1. Press the Menu button on the control panel.
2. Select Admin Menu
3. Select Maintenance Mode
4. Select Initialize NVM

Well since you know how to enter diagnostics. Go to DC132 and select all copier nvm. Do an all copier nvm initialization, it will correct any default errors in the memory.
You will just have to then reset things like the power save timers and I would also go in and do a dc604 registration adjustment.

HOW IT WORK AND DIGRAM

You can't. A reset is a #6. A #9 resets the NVM - the NVM is the firmware that makes the printer function. If you have reset the NVM there is no way to bring it back again unfortunately. It should only be used by HP in their repair department when they are seeking to replace the firmware components.

How did you resolve the color problem? I am having the same issue on a Xerox Workcentre 24. After initializing the NVM, the auto-feeder does not work and the colors are off. How did you resolve the colors being offset?

If your device still does not respond after performing "reset", disconnect all cables, including the car adaptor, from your device. Slide the battery ON/OFF switch on the bottom of the device to the OFF (left) position. Then slide it to the ON position again.

In tray one there is a hidden compartment take a flat blade screwdriver to the cover as you are looking directly down at the top of the front of the drawer you should be able to open the top of the compartment. In there is what is called the birtcertificate for the machine and the original NVM settings are in there.

That has to be done with the diagnostics software. That has to be on a laptop computer to access the NVM. Once connected to the machine from the computer, you can reset the NVM and all other settings back to default.
You can try shorting the NVM battery to reset the memory but I would NOT recommend that move .
