Our school newspaper owns a Phaser 7800DN that we use to print proofs on tabloid.
The printer has worked for a while but now it crashes after about three minutes. It will turn on and then print the status report and work normally and be accessible from the web browser but the display will read 'warming up' for the duration of those three minutes. After three-ish minutes, the display will become unresponsive (if you try to tap something it will turn black) and the printer will be unnaccessible from the web browser and it will continue to spit out status reports until the main power is shut off.
Thanks in advance for the help.

Will it stay on if you unplug it from the LAN?
The same thing happens with no USB or LAN plugged in. It's responsive for about three mins and then goes totally unresponsive and has to be shut off with the main power. If I don't shut it off with the main power, it reboots about a minute later but the display is unresponsive and it is unavailable on the network.
It could be a corrupted file on Hard Drive or bad Hard Drive. Try to do a firmware restore using AltBoot procedure to reload Firmware on Hard Drive.
I made a folder on my flash drive called 'altboot' and put the firmware file in it and plugged it into the USB port. The printer did nothing and booted up regularly. Any ideas?
To prepare the USB thumb drive for an AltBoot restore, create an ALTBOOT folder, in the root directory. The folder name must be all uppercase. Next, using Notepad or similar utility, create a zero-length file in the ALTBOOT folder called FORCED_UPGRADE with no extension. Again, this file must reside in the ALTBOOT folder and be named exactly as shown. Finally, copy the latest firmware file (*.dlm) to the ALTBOOT folder.
Turn the printer Off.
Insert the prepared USB thumb drive in the USB Port on the printer’s rear panel.
Turn the printer On. The printer reads the USB port and begins the restore process.
The splash screen displays the ENERGY STAR logo while the printer reads the thumb drive.
The restore process begins with Check Firmware Version being displayed.
Next, the Software Upgrade screen is displayed. Depending on the system configuration (Trays, Finisher) the process can require approximately 20 minutes. The Software Upgrade screen changes to reflect the current subsystem being restored.
After the firmware update process is complete, the AltBoot Complete screen is displayed instructing you to remove the USB thumb drive.
Remove the USB thumb drive from the printer’s USB Port.
Wait for the printer to reboot and return to Ready To Print.
