MP C4000 fuser not setting properly

[ABS tect]

We are replacing the fuser in a MP C4000 and when we put the new fuser in, it said that the fusing unit was not set properly. We have tried 3 different ones, 2 from a MP C5000 and one from a Lanier ld540c, neither worked. All three look identical to the one in the 4000 but it won't take it for some reason. Is there a reset code for the fuser or some reason why those are not going in?

No code to reset this message, it all done automatically.

Make sure the connector on the inside of the machine has not broken.

I've seen the sensors on the left hand side inside copier get knocked out of place. Doesn't recognize fuser.

You mentioned you tried 3 different fusers and all had the same issue?

As recommended, I'd check to make sure no sensor was knocked loose. Beyond that, check the pins in the connectors on both the fuser(s) and the MFP? Make sure they're not bent and are actually making a secure connection, that could cause the error message to appear.

Let us know what you find.

Also, off thought for a shot in the dark. If after checking pins and sensors don't work, you may need to trace back the wiring from the connector on the MFP side, make sure the wires are not pinched or damaged. This is a slight chance, but being that you tried more than one fuser and if the pins and sensors are fine, it may be a wiring issue with the MFP, couldn't hurt to check?

Yea I checked all the pins and such and everything looks in place. And I can check the wiring on the mfp but what is weird is when I put back the original fuser, it fires right up. So that makes it hard to believe its the wiring.

Ok, hmm. You did mention you used other fusing units from other machine models? Check the parts catalog to make sure the Fusing units are actually the same unit? Could be that even though they look the same, they may not be identical, if so that could cause it to throw the error code.

I'll attempt to think of other solutions too, that's the first thing that comes to mind when you mention putting back in the original, it fires back up. There may be a compatibility issue?

Right, that's exactly what I was thinking. And I'm checking on that. And if that's the case, and we don't have one of those machines, I will probably just rebuild the original fuser and be done with it. Just strange because I have switched fusers in and out all the time in those machines, never checking the model. Thank you!

Good luck, let us know what you find.


Though at this point, if you have the ability to rebuild the original fuser, I'd probably just go with that. Being that you can confirm that one is at least "seated" properly. Most likely less expensive to go that route as well.

This happens when we use fusers from the printer models in the copiers, we have to swap a wire in the fuser connector. Could this be the same cause here? I dono, maybe

You have to swap a wire on the actual fuser? Could you explain that a bit more?

Re: MP C4000 fuser not setting properly

Am I allowed to say this on here?
For the printer version, you have to remove the fuse thats just on a white clip, from the bottom of the fuser. Then pull out the connector and swap 1 red wire over 1 notch. I cant exactly say what one on here but what you are describing sounds like you may be using the printer version of the fuser without modifying it

Sounds like the fuser set sensor has become dis-lodged. Happens too frequently on these.

According to my service manual, 5803-046 is ITB New Unit Detection.

Input items for the fusing unit are as follows:
5803-083 Fusing Destination Detection Japan, Europe, Taiwan
5803-084 Fusing Destination Detection North America
5803-087 Fusing New Unit Detection
5803-088 Fusing Unit Detection 1
5803-089 Fusing Unit Detection 2
