Re: Technical Black Imaging Unit Replaced,Error message...
These units are automatically reset with a fuse. When you put the imaging unit in it will completes a connection which resets the count then simultaniously blows the fuse. Sometimes the fuse blows before the reset, which is what it sounds like happened here. The machine should print normally but the error will persist until the unit is replaced with a new one. Is the the imaging unit an OEM unit or remanufactured? Whoever you got the unit from should replace it as defective free of charge. If it is OEM you might have to go through Xerox to get it replaced. I don't know if the Big Box stores will.

The Drum Phase Sensor for the named Imaging Unit indicates that the drum is out of position.
Reseat the indicated Imaging Unit. Cycle the printer's power.
after these steps it gets a lot more detailed and you would need to be an experienced tech to understand everything and follow the steps within a timely manner, if reseating the cyan imaging unit doesn't fix the problem, then you will have to call for service.
Did it specify a color you should replace? The machine has 4 image units (CMYK) each with a different part#. Replacing them is easy, no tools required. Open the top door, lift out the entire image unit, move the toner over to the new unit, and lower the image unit. Here are the part #'s for the 7400 for each color. Iteminc.com has these online. C - 108R00647 M - 108R00648 Y - 108R00649 K - 108R00650 Good luck, hope this helps. Thanks for using FixYa!
The black image unit of your machine should be replaced soon. It is a maintenance item and is very easy to change. They cost about $350 new, but you can buy one much cheaper rebuilt. Here is a video I made to help explain what it is you need to change and how to do it. Good luck
www.support.xerox.com -phaser 7400- support -fault code-941 says cyan or magenta toner failure, but the solution says to
1. remove & reinsert the cyan or magenta imaging units.
2. replace imaging units .
