Question about Xerox Phaser 7400/DXF Laser Printer

Open Question

LCD screen on the printer is scrambled

We have a Xerox 7400 DN. The LCD control panel on the front looks like its scrambled. Its redrawing funny and you cannot navigate it properly using the buttons. The only way to configure it is through the web browser. I am not getting any error. Is there any way to run a diagnostic on the printer?

Remove the tray, first look for a piece of paper that has come out of the tray inside the tray area.
Make sure the rolllers are snapped into place. The easiest way to verify that is to remove another tray and compare them.
Look to see if all the switches and actuators are in place.
Make sure you hear the tray up motor running when you close the tray.
Also inspect the paper tray itself for broken items. Compare it to another tray.

That is a motor driver board fault.
May be that board itself, Could be a waste bottle interlock not being made.Possibly the engine control board.

SOURCE: PRINTER ERROR

There is a tiny little magnet that falls off and/or has reportedly been put on backwards (fell off is what happened to me) on the auger assembly. It's near the black auger chute on the end of a shaft. It's tiny--a little bigger than a grain of rice. I had to replace the auger shaft assembly but if you can find the magnet, you can super glue it back on.

SOURCE: install wiper on xerox 8560 dn

Hi,

The user guide is available here http://www.support.xerox.com/go/results.asp?Xtype=docs&prodID=8560&Xlang=en_US&Xcntry=USA&prodName=Phaser%208560

Also, I think there are two wiper blades on the 8560, one is on the maintance kit and the other is supposed to be removed, that was the old 860 that could remove theirs. Perhaps cleaning it will be fine. just open the top of the machine and its right there, give it a wipe and it should be fine. The other wiper blade on the maintanance kit and here is a link below to show you how to clean it!

The display does not work, it's just a blank screen


We have had that problem before what you have to do is replace the control panel. Part # 802K93860. You should check with xerox if the machine is under warranty and maybe they can ship you out a new control panel for free. It's worth a try. Anyways good luck.

Phaser 7400 LCD is blank. How can that be fixed?


Once the LCD is gone blank that means you have to change the control panel. it's not difficult to change, all you have to do is remove the covers that are behind the the control panel. Once you have removed the white covers you can now unscrew the metal hinges. Then you have to insert a flat head in the small cracks behind the control panel that opens the control pane blue covers. Now you disconnect the data cable that connects from the control panel to the machine and that's it. Hope this helps
