Paper jam My 4-year-old Magicolor 2350 has a problem with paper jamming. Every time I send a document to it, it always returns a paper jam message, but only for the first page. When I remove the jammed paper, it always has a single crease down the middle. Thereafter, all the subsequent pages print fine. I spoke to Konica Minolta, who told me it was a sticky transport solenoid. Is it worth fixing, or should I buy a new printer?

replace the fuser unit. and replace the transfer roller and belt,

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

check between the rollers there will be small bits of paper jammed in that is the reason.

it sounds like a sensor that does not return to "home" position

If a document jam occurs during a transmission, the message "DOCUMENT JAM" is displayed. If this occurs, follow the procedure below. It is recommended that a duplicate from a copier, of the jammed document be used to reduce the chance of a jam when resending the document.
See Chapter 3, "Loading Documents" for document specifications and recommendations which may help avoid paper jams.
Note: The power can be left ON when clearing a paper jam.
Typical Causes of Document Jams
Recommended Procedure
The document is fed at an angle.
Adjust the Document Guides to the edges of the
document.
The document paper is too thin or too thick.
Make a duplicate using a copier and use the copy
as the sending document.
Document has tape or pieces of paper taped to it.
Remove the tape or make a duplicate using a copier and use the copy as the sending document.
The Control Panel Cover is not fully closed.
Close the Control Panel Cover fully.
The document is stapled. Remove the staple(s), or make a duplicate using a copier and use the copy as the sending document.
Basic Troubleshooting
1. Remove all documents from the Document Support.
2. Open the Control Panel Cover.
3. Remove the document jam. Remove any pieces of paper, paper clips, or staples that may have caused the jam.
4. Close the Control Panel Cover.
5. Verify the display has returned to the Standby Mode.

I am forwarding a list of manual that will help you with the paper jam issue and also would help you with any future issues related to your printer.

How do you clean the rubber rollers, hope you didnt use solvent....
Use dry cloth with dishwashing fluid only to wipe the rollers.  You will notice the increase in grip immediately.
