Cyan Imaging Unit Failure, U28 Error Code

I got a U28 Cyan Imaging Unit error code on front panel of the Phaser 7300. I cleaned the contacts with alcohol and a Kimwipe, cleaned the LED's with the alcohol pad, no luck. Turned switch off, then back on. Cleared error, then attempted to print again. Paper jammed in Door A, cyan imaging unit failure 4 more times. Replaced cyan imaging unit, still continues to fail.

I just got that error couple of weeks ago on my 7300. I did everything you did and nothing so I ended up visiting www.iteminconline.com. I called them up and they told me to check all the cables on the engine control board 116-1538-00. I made sure the white data cables where connected and still nothing so they recommended me to buy a engine control board. That did the trick. Hopefully this will help you.

    sorry guys I put this information on the wrong blog anyways ... Before doing the engine control board.. make sure you got all the wires on the Toner sensor board connected if they are alot of the times the Toner sensor board fails before the engine control board. Remove the top cover that is where the toner sensor board is located.

The only thing I can suggest is to check the contacts that the imaging unit goes into, and i can also be the imaging unit itself. If i am not mistaken, you should be able to swap imaging units from another color just to see if the error goes away. But if this does not help, you will need to get it serviced. we have fixed these before, and its not a quick fix.

Error u26 phaser 7300


U26 is Yellow Image Unit failure. It may be that the contacts are dirty - spilled toner?? Give it all a thorough clean, especially where the electrical contacts are - if still no luck, then a new yellow IU should solve the issue.

Xerox Phaser 7400 U28 error message


The Service manual says:


The Drum Phase Sensor for the named Imaging Unit indicates that the drum is out of position.


Initial Actions:

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.

Hope that helps

We have a Phaser 7400. It continues to give us


If you've already changed out the toner cartridge and the problem persists, then it could be several other parts that are either defective, dirty or blocked.

You may want to contact a certified Xerox technician and have them look at the Imaging Unit Agitator Bar and the Low Toner Sensors for Cyan/Magenta. There could also be a faulty toner supply motor.

Xerox phaser 7300 toner cartridge problems


Hi,
Sometimes on this machine as there is a lot of loose toner around it can cover over the sensors in the machine, what I would advise is to remove all the toner cartridges and check for the copper contacts on both the machine and under the imagining unit (which the toner is placed in). Once you have cleaned that away slowly close the lid and reboot the machine and it should return to normal. Its just toner getting caught up in the sensors. Follow the instructions below, when you remove the unit, lift it over your head to find the copper contacts and clean them, be careful not to spill toner everywhere. Good luck!

Reseating the imaging unit
    Remove the toner cartridge:
  1. Open the top cover.
    openthetop196x185.gif
    caution_image88x30.gif The imaging units are sensitive to light. Do not expose the imaging units to light any longer than necessary to remove it and cover it. Failure to follow these instructions may damage the imaging units.
  2. Identify the color of the toner cartridge to be replaced (Cyan, Magenta, Yellow or Black).

  3. Move the orange lever on the toner cartridge to the right so that it unlocks.

  4. Lift on the back side of the toner cartridge first, then guide the cartridge out of the printer.

  5. Set the toner cartridge on paper to avoid any toner spilling.

    Reseat the imaging unit:
  6. Lift the imaging unit straight up out of the printer.

  7. Line up the guide pins with the printer's frame and lower the imaging unit back into the printer.

    Reinstall the toner cartridge:
  8. Install the toner cartridge by guiding the front onto the new imaging unit first then lowering the back.

  9. Move the orange lever on the toner cartridge to the left so it locks.

  10. Clean the LEDs with the supplied wipe.

Xerox Phaser 7300 Error U20


1. Contaminated or damaged Imaging unit contacts. - Remove and clean the contacts and inspect for damage.
TROUBLESHOOTING TIPS AND HINTS:
Imaging Unit Failure message occurs because the printer cannot detect imaging unit motion, up-and-down. The Transfer Belt drives this motion, and the Drum Contact Assembly detects it. 1. Swap the Imaging Unit Cotact blocks between two imaging unit positions. If the problem follows the Contact block, it should be replaced. 2. Open the Top Cover and defete the top cover interlock switch. The color imaging units should raise in succession, cyan, magenta, then yellow, and then all lower at once. If one or more imaging units do not raise smoothly or drop prematurely then replace the Transfer Belt assembly.
