There is a set of clutches in on the upper back side of the right side door.
The inverter clutch tends to go bad on that cluster.
But if you are replacing one may as well do both. They are electromechinical clutches.

I think you might have a Spring missing for the Waste Toner Full Sensor. The machine tolerates the sensor status for 2K pages and then shuts it down.

Truthfully, it is really hard to describe in a few sentences. It belongs in the frame wall under near where you have the white waste toner section of the Transfer Belt. This spring pushes a flag up that hits the Paper Entrance Sensor (yes, near the bypass tray)

The PN for the spring is 116-2050-00.

Usually it should do it automatically once you have replaced to a New image unit. If you are still getting that error then you will have to change the engine control board. You can first try this tip reset the nvram from the service diag mode some errors get stuck in the NVRAM and won't get off until a reset is done in the NVRAM. Hope this helps. Iteminconline

you must configure the page size, because the configuration jams have a page shorter than the product that you put to print.

Sounds like some of the magenta toner is left behind on the drum. The only way to fix it is to get a new cartridge.

This depends on what you are trying to print and with what software. Most likely, you need to choose a higher print resolution in the software before sending to the printer, but more details would be required to give a precise response.

You set the resolution in the printer driver before sending the data to the printer. Exactly where this will be will depend on which OS you are using and which software / driver you have installed.

Various possible causes - the most likely are :1. Dirty registration sensors - remove IUs and transfer unit and inspect / clean sensors.2. Damages / worn IU drive gears - inspect. Replacing the gears isn't a small job, if this is your problem.3. Faulty colour registration shutter - you can check this is working in the service diagnostics menu.4. EEPROM problem on the controller board - replace main controller board.These are in order of likeliness. For further information, take a look here.

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.

U2 is an engine EEPROM failure - you'll need to replace the main board to fix that, I'm afraid.

The problem is a crazy design in the printer itself! I've now found a reliable fix for this problem which is relatively easy to carry out. You will find the details of how to do it here :www.michelsplace

Hi,

The only thing you can do is attempt a reboot and hope for the best, otherwise call out an engineer to repair it! Or you could try and NVRAM reset but I'm not sure if that will work and be careful because you will set the machine to factory settings and may have to do a colour calibration all over again. Let me know how it goes.
