72-87 FS-534 Folding unit

[Genotrom]

I recently retired an FS-534 with a folding unit. I don't know its history but it seems in good condition. No jams in the two output trays but only when I try to fold.
The paper is rolled up before exiting the book exit. As if it were stuck. Some idea?

Take a picture of the jam that could help.

Go check the theory of operation on that unit.
Jig the door take of covers if you need to, take a peek if anything is viable.

Its got a "knife" and 2 rollers that does the business.
Sure its something simple.

Is the fold off center by about 2.75 inches?

Thanks! The card stops at this point. There is no way to get it through. There is something that is not clear to me

It appears as if there is something blocking the paper path, like a displaced mylar guide, scrap of paper or the folding knife is not at home. You say that the "card" stops where you circled in the pic. Do you mean cardstock is the media being used? If so, how does the folder do using plain paper? And if it is cardstock is it within specs for that finisher?

Hi, try to check if the cartridge is mounted correctly

it's plain 90g paper. I recovered this finisher from a printer graveyard and there is a good chance there is some piece missing or something is blocking the paper.
But without taking it apart, we won't be able to know. The other trays and stapling work, only the third tray with folding is the problem. So, I will try to disconnect when the printer is not needed. We update soon

Don't think i should go all the way thru there. Think it stops there to get stapled and then reverse back again.

thanks everyone for the support. I managed to get a video sent to me:



In the video it is not seen but the paper comes out of the second tray and then returns for folding. At this moment it jams.
