C452 getting 99-01 jam from tray 3 ONLY when printing, NOT when copying

[srvctec]

i had one a long time ago that the actuator was worn and caused an engine jam.
i believe the timing played a role.
the issue went away when set to thick(X), thats where i got the timing correlation when it stopped jamming.
when back to plain it jammed again.
i hope its that simple. he's gonna test from his laptop to eliminate a driver issue.
fingers crossed it just software/driver related.

Good idea on the thick setting. That's another option I hadn't thought of.
Oh, and I'm "he's", the OP.

TL;DR, lol J/K
i lose track sometimes.

I think it's fixed now. (I learned a long time ago to never say it's definitely fixed so I don't get bit in the a$$)

Just to clarify, here are photos of what I was getting (only when printing because I never got it to jam when copying).





I went back to the customer's office today and printed a 16 page 2-sided document from my laptop and it jammed after the 3rd page was out in the finisher so I knew it wasn't anything to do with the file or their network/drivers. Once I discovered the play in the exit drive gear below (I noticed wear on the previous call but not the play), I put a shim of paper on the flat of the "D" to remove the play and ran the same job as before, twice without issue.

Here is a video of part of what the issue was.




Went back to the shop to get parts and replaced both gears, both bushings on the shaft, and the eject drive gear that always gets worn over the fuser that also drives the above gears. Had the customer test with her 15 page 2-sided print job and it jammed exactly the same as it did for me but on about page 8 or 9 out. Well crap!

The only thing left was clutch 3 so I replaced it as well and got two test jobs from the customer without issue. Makes no sense whatsoever that it wouldn't jam on copies but I gave up years ago trying to make sense of some copier issues.

thats an oldie!
i remember using pieces of a box cutter blade (the one where you can snap off a piece to get a fresh edge) to "Shim the D"
man that brought me back to the analog days and lift gears just hearing you say that

The bottom door front side latch just needs a slight crack to cause jamming on these.
After not being able to get the exit drive gears no more i resorted in drilling the gear centers out and installing brass bushings in there.
