Question about my "Paper Jam at Transfer Roller" issue
Thank you SO MUCH for your feedback and advice. I did call Konica, and they only told me about the one sensor in the middle of the printer. It looks like a little black cheap pin right, in the middle of the printer, between two roller looking things? Is that one of them? I pulled that out and the pin is now visible and hanging out, which I believe is what it should be, but it's still reading the error message.
You did mention another sensor that I can't see to understand where it's located. Where exactly is the fuser, and where would this other sensor be at? Perhaps, that's the next one that I need to fix and it should work?
I don't want to be taking this printer to a shop, as I know the moment I do, they'll charge me $200+ just to look at it, when all it could be is a jammed sensor.
Please help if you can. I'd greatly appreciate it. You can email me at email@example.com directly. It's much easier for me to check that way.

Replacing the pickup rollers seems like a drastic first step. I would check to make sure that the paper being used is suitable for this printer and it is in good consition. You might try a different paper to see if it makes a difference.
yes 2 things. 1 bad sensor. 2 bad paper. change paper brand and type. use hammil mill 20# long grain brightness90 and above to test. if this works you need better paper. if not you have a bad jam sensor and need a tech to repair ir.
My 2400W was standing a long time without being used, and when I wanted to use it, it made a very faint image and showed "paper jam at transfer roller". Also, the image stayed on the transfer belt, but never got transferred to the paper. I tried a lot of things, nothing worked, but the message from weirdal1968 above pointed me in the right direction.
I eventually scratched / scrubbed / cleaned the copper pad on the left side of the optical imaging drum - this copper pad probably receives the bias voltage for the imaging drum from a springy stainless steel wire. There was some visible darkening of the copper pad where the stainless steel wire touched, this is what I cleaned. And then, presto, problem solved - the image came out great, and no more "paper jam at transfer roller" error message.
there are two black plastic flags that detect paper jams. one is high up just below the fuser unit. The other is roughly half way up the printer between two small transfer rollers very close to the opto sensor. Apparently it frequetly gets jammed behind the plastic cover, and once jammed you would never realise it is there.
I managed to prise it out from behind the cover and the "paper jam at transfer roller" message was cleared.
Unless you know it is there and hiding it is not obvious at all that anything is wrong.
