Konica Minolta Bizhub 227 paper jam before fuser

Re: Konica Minolta Bizhub 227 paper jam before fuser

Hi Femaster....
The fuser unit is fine because if i remove image roller and run a copy the paper goes through the fuser unit right to the exit and both fuser unit and paper will be hot.

The image roller is driven by the image drum, so what difference does it make with or without the image roller. I mean other than pulling the paper through what other roll does it do?

Sorry about that, I looked back and I apparently missed the post where you had mentioned that the fuser had been replaced and that paper does go through if you remove the transfer roller.

I was looking through the recent parts manuals and I see that the 227 has had a "refresh". There are some fairly significant parts changes in the transfer/duplex assembly and the exit assembly. I have not yet found any information as to why this was done, but perhaps the problem you are having might be due to something they have corrected in this refresh. Unfortunately, I haven't been in front of very many 227 style machines, so I haven't come across much with them and at this point I'm out of ideas.

Is you drum scratched on the in side? The transfer roller gets driven from the drum unit check if the contact on the gears are ok could be that its not rotating.
Found that the customers can miss form the metal guide plate on the transfer roller assy, but that will cause the drum to scratch on the far side.

Your missing something simple.

I m working on it again tomorrow morning. Yes i can see I m missing something simple. I have to figured out why it does not jam when i remove the second image transfer roller. Again before it started jamming paper it could copy but there was some uncomfortable noise when copying. But now i do not here that noise anymore which makes suspect that maybe the drum unit is not running.

Double check that transfer roller is driven. Simple test, make some mark on it and see if mark is moving.

Tend to agree with you, as far as i can remember without looking at one the gear that drives the transfer roller in on the drum flange.
So very possible that your drum is not turning.

I will check the drum if its turning but when i look at Drive Motor1 its spinning. Something i did passively was turn motor 1 with my hand and to my surprise it was so stiff at first then at some point it turns smooth and free.

According to what I'm seeing, it is M3 that you need to spin to test the drum movement. Spin it by hand and see if the drum turns.

Re: Konica Minolta Bizhub 227 paper jam before fuser

I wonder if these motors are serviceable......

Not really. Had one that i fixed by changing one of the coil driver FET chips out.
But they are real tough so will not blame the motor first, and they will produce an error code if they return a lock signal.

I managed to sort out Bizhub error 227. Thanks to all your contributions, i really appreciate to be in this forum.

Now i have another problem, Ricoh MP2553SP ERROR CODE SC554-00. I changed thermistors and heat roller but the problem persist. If i try to access SP Mode it kicks me out before i finish punching in access code '' clear mode,107,stop keys. The machine beeps and display something about jobs pending. When i try key SP Mode access keys as it display error message all keys dont respond.

1. What about posting resolution of your problem?
2. Why to not start a NEW thread in proper Ricoh forum?

You're walking on slim edge, better correct it before someone with less latitude give you bad reputation aka red card.

Post a new thread in the Ricoh forum switch machine off and unplug network cable and fax make sure there is no TX or RX at the time. Only KM here.
What was the solution to the problem?

easier test mark the drum in non-image area. open n close door see if mark on drum moves.
