[Jamming] Konica Minolta Bizhub 227 paper jam before fuser

[Khumz]

HI guys
I have a bizhub 227 which jams paper before it enters fuser unit, actually the paper gets shrinked right under the fuser unit. Its coming up with error code 30:03 which points to exit sensor PS3, i changed all suggested components but still get jam at the same point. But if i remove image roller the paper goes through but without anything copied of course. Anyone with suggestions please help. My client is desparate.

Hi, so it's not easy to help you.
1. What is the printer counter?
2. What did you really replace?
3. Have you replaced/cleaned the paper dust remover unit? At 150k the manual recommends replacement. There is an incredible amount of dirt that could dirty the 2nd transfer roller and therefore jams.

I did not check the counter but it should be more than 150k. The fuser unit and the image tranfare roller were changed. This machine could copy but failing on duplex. Before i could do anything i ran five none double sided copies and it was all good. I then attempted to run one double sided copy and it jammed the paper. I opened the side cover, removed jammed paper and from there on its jamming paper below fuser unit. It is clearly showing that the paper succesfuly pass through registration assembly and gets stuck below the fuser unit, as if the fuser unit is not turning or its totally closed.
As i mentioned on my first post that if i remove image transfar roller the paper goes through without any problems at all but it will be blank of course.

There must be something out of place. Is the image registration ok when you pull jammed sheet?

Re: Konica Minolta Bizhub 227 paper jam before fuser

The image registration is fine. The paper do not get stuck at all, the moment i open the machine the paper just falls out. The lead edge of the paper will be facing the entry into the fuser unit. The paper then multi- fold the whole A4 page kind of held against the drum.IMG_20200214_185716.jpg

Check registration sensor and it's spring.

Re: Konica Minolta Bizhub 227 paper jam before fuser

I changed the sensor, will double check though

Re: Konica Minolta Bizhub 227 paper jam before fuser

The registration seems to be ok and mind you this jam happens after the paper has passed it.

How are the internal gears that make the 2nd transfer roller spin?

I know 423 isn't the same as a 227 but I think they are similar enough this might help:

please explain a little bit

Re: Konica Minolta Bizhub 227 paper jam before fuser

Have you removed the fuser and inspected it? Since it's obviously not getting pulled into the fuser (paper just falls out when you open the door), that is where I would start.

Maybe there is still a sheet of paper accordion jammed in the fuse entrance blocking the path. Try turning the fuser by hand and see if it will turn. If it's not turning I would expect a service error, but if one of the drive gears is broken or something, it's possible the copier sees the drive motor turning and thinks everything OK.
