Xerox Phaser 7400/DXF Laser Printer - Answered Questions & Fixed issues

It's hard to set up the mpt tray when the display is out. Send the job to the printer with no paper in the mpt. The printer should then ask you to put 11 x 17 in the mpt. Hope that helps.

This may be a high voltage problem.
Am not familiar with this machine but is a generic fault.
Ensure contacts to drum/cartridge are clean.
Next
If possible, unplug machine, open up and ensure all high voltage connections are good.
Good luck.

As far as I know it's under the cleaner assembly, usually with an orange handle on. Should pull out. Good luck.

See if maybe this manual has the answer. To much for me to read. lol Good luck. Xerox 7400DXF Phaser Color LED Printer Administrator Manual

If the unit is remanufactured or if you know how, you will have to disassembly the imaging unit and replace the fuser that blowns or simply just solder it. http://www.uninetimaging.com/downloads/technical/xerox/english/Xerox_Phaser_7400_Reman_Eng.pdf Graphic 27.

Hope this helps if you need more help let us know at iteminconline. iteminconline

reseat the imaging units and check if the guides in the machine are in the correct position

The problem is with the top cover assembly. It could be a few things. I would first try the toner sensor flags(the magnet may not be strong enough to read properly). Also replace the toner cartidge because it's magnet may also have gotten weak. Third, I would try the Toner sensor board.

I have had this problem with many printers and normally it is just the flags because of the weak magnets.

You can download the Xerox printer drivers from theirsupport WEB site. Please click on this link and select your model printer todownload :-http://www.support.xerox.com/support/enus.html

It is probably the yellow Image Unit (the toner fits into it)

Did you load up the "Universal Printing Driver"??? it only prints monochrome on most Xerox printers...You should use the PostScript Driver for this printer.

Solution : Power OFF the Printer, Wait 10 Seconds, Then Power ON

1. Press the power switch, located on the left side of the printer, to the OFF (O) position
   
   
2. Make sure the printer remains powered OFF for at least 10 seconds.
3. Press the power switch to the ON (') position.

Solution : Remove Additional RAM (Memory) CAUTION: Circuit boards and modules are electrostatic discharge (ESD)-sensitive components. These components are designed to be protected from damage due to ESD during normal operation; however, proper static control precautions should be followed to prevent damage while handling these components.
Power OFF the printer and remove any RAM DIMM that was not originally installed in the printer. After the additional memory has been removed, power ON the printer. If the printer returns to normal operation after the memory DIMM has been removed, replace the DIMM.
NOTE: Third party memory is not supported. There are no hardware or software modifications to ensure third party memory will be compatible with the printer. I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_8b8c2cd6ce148309

start a print from tray 1/manual feed and just as the trailing edge of paper is entering the machine; quickly open it to stop print and take out the cartridge and look at it's drum and the paper underneath. If the issue is there at that point then it would point to loose toner residue underneath the cartridge. if not then the fuser area has to be cleaned. Wipe the area clean with a lint free cloth, do not use compressed air.....

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

The average cost of this machine is $2500. You may purchase a used one at a national average for $2500 or sell a used one for a little less.

• Turn off the printer. Turn on the printer.
• As soon as you see XEROX start moving across the display hold down the back and help buttons until you see "beginning service mode" on the display.
• Release the buttons, it will now come up in the service mode.
• Scroll down to the function menu, hit ok, scroll to clear isc fault, hit ok. Hit the back button to get back to the first menu then exit diagnostics, hit ok when it asks if you want to restart in customer mode.

Error 928 refers to the fuser motor failing. Problem could be with fuser motor, motor drive board or engine board.
One other possible cause would be if you are sending too thick a card stock through the machine, this can cause drag on the fuser which the machine interprets as a motor failure.
Hope this helps.
