Question about Xerox Phaser 7750DN Laser Printer
At work we have had the same problem as some mentioned below, the printer rebooting when going from 10.5 to 10.4 Macs and Windows comps. After around 3 months of stuffing around we have finally fixed it using this file download:
To install it just typed the IP address of the printer into web browser, chose Print>File Download>Choose File and then hit the green button.
Hope it works for others also. So far I have been unable to make the printer crash again printing from the different platforms.

We had this same issue for 8 months. Download and install the firmware update. That'll do it. http://www.support.xerox.com/go/results.asp?Xtype=download&prodID=7750&Xlang=en_US&Xcntry=USA&source=XOG&prodName=Phaser%207750

I had this problem yesterday with the xerox 7750. This was the situation:
When printer is switched on, it prints a start up copy but while processing to print the copy, you can navigate between the current menu on the screen and just after it finish printing, you can no longer navigate the screen as it seems as if it has stopped responding and then the machine switches off and restarts again in a loop.
To resolve this problem I took these steps:
1. restarted printer
2. While it was processing to print the start up page I cancled the job using the cancel button and doing this allowed me to be able to navigate and also see other menu like printer troubleshoot etc
3. I navigated to network settings and reset the network configuration, reset NVM Ram configuration and rebooted printer each time. but do note that each time I rebooted i performed the steps all over again from steps one.
After all these, check the start up page of the previous prints it had done and the new one it has and you would find out that the network configuration is different and that solved my problem.
Printer has been functioning properly.
Please, try at your own risks.
Thank you and hope this might help some pple out there.

This isn't a solution... just a narrowing of the cause. I purchased a used 7750. It tested fine, but the color is way off, can't get it right. So I figured I would take this motherboard and put it into my old 7750 that was having the reboot problem listed here. My old printer works with the swapped mother board. So it is definitely something on the motherboard. Problem is, the color issues from the use done I bought, transferred over with the mother board. Some people have suggested the EEPROM, also RAM and Hard drive. I switched the EEPROMs and switched the RAM to to the old printer motherboard. Restart problem still exists. So it's neither of them. I am going to swap the hard drive next. If it's not that, there really isn't much else I know to try and will give up.

We are having the same continual reboots with no cause although even more so since a tech came out to redirect all of our computers to a new server which is very strange. We tried everything...update drivers (even generic), addresses, tried different applications etc., etc.. I didn't try resetting NVRAM although I believe at this point it is a chip on the main board.

Same problem here going on for months now. Mixed mac / pc environment and started happening around when Leopard went into the environment. Just crazy that there is no solution for this yet.

From the printers web page, try seting static ip address, turn off all unused ports. In your printer driver set the port as LPR or tcp/ip configured with port 9100 or lp with byte counting enabled.
A faulty file can cause the printer to roll over. Are you using a postscript driver? Try using a PCL driver. Reboots cannot be blocked as this is a bailout for the printers logic. As for continual reboots with no cause - replace eeprom (little lack IC chip with 8 legs) on main board (top of machine)

We did the SLP and DDNS turn off but the reboot problem is still there. I think it is related to QuarkXPress under Mac OS 10.5.
I had the idea to lock the reboot fonction of the printer with a password to avoid it but can't find the way. Maybe Quark send some kind of order to the printer to reboot itself?
If anyone know how to lock the reboot with a password, let us know...

Via web interface go to Properties -> Protocols -> TCP/IP turn off SLP and DDNS. This fix was suggested by Xerox.

In the print settings select "Print as image" and make sure "Fit to page" is also ticked, if printing from a Mac then this can be found in the pull down menu in the print window and selecting "Acrobat Reader 4.0" then make the same selections as above.
