Phaser 7800DN showing Warming up and it won't start.

Product Name: Phaser 7800DN
Operating System: macOS 10.13 - High Sierra

Hello,

We have a Xerox Phaser 7800DN that since yesterday has been showing "Warming up" on the screen and doesn't let anybody connect to it.

I spoke to support today and they told me to do some stuff, but the printer still shows the warming up message.

Any ideas about what I can do to fix this?

Thanks.

Hi,

Does the machine is booting up? Can you provide a fault code? Have you reinstall the software by AltBoot?

Re: Phaser 7800DN showing Warming up and it won't start.

The printer shows as if it had booted up, it shows me the IP address on the screen, but it keeps saying Warming up, I can ping it from any computer, but I cannot access it's web interface or print to it.

There is no fault code anywhere, just the light keeps blinking (like it never finished booting up)

What do you mean with "Have you reinstall the software by AltBoot?"?

Thanks.

Download the firmware from here: https://www.support.xerox.com/support/phaser-7800/downloads/enus.html?operatingSystem=win7

and try to install the firmware following the instructions below:

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.

 
  1. Turn the printer Off.

  2. Insert the prepared USB thumb drive in the USB Port on the printer’s rear panel.

  3. Turn the printer On. The printer reads the USB port and begins the restore process.

    1. The splash screen displays the ENERGY STAR logo while the printer reads the thumb drive.

    2. The restore process begins with Check Firmware Version being displayed.

    3. 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.

    4. After the firmware update process is complete, the AltBoot Complete screen is displayed instructing you to remove the USB thumb drive.

  4. Remove the USB thumb drive from the printer’s USB Port.

  5. Wait for the printer to reboot and return to Ready To Print.

I created the folder, and put a zero size file called FORCED_UPGRADE in it along with the .dlm firmware file, but it did not read it after I power recycled it, all it did was back to saying warming up.

Try another USB thumb drive (formated FAT32). Some USB drives are not recognized by machines. And if this not worked it is possible to need another firmware level.

Keep in touch!
