Weird one here. I've dealt with lots of 99-01 jamming calls over the years but none like this one. In the past when it's happened, it's always been on both printing and copying. But this one is just like the title says. C452 with 367.5K is getting 99-01 jam from tray 3 ONLY when printing, NOT when copying. None of the other trays jam on the same print jobs that cause a 99-01 on tray 3. I can run single and 2-sided copies all day long with no jams whatsoever from tray 3.
Initially, I went for something entirely different late yesterday afternoon (folding corners from tray 4) and was told by the customer that another tech (coworker) told her we couldn't fix tray 3 because it needed a part that cost too much and she would just have to do without the use of tray 3, so for the last 3 months she has had a note on the tray to not use it. WTF!!?? This is a contract customer and that's NOT how we are supposed to handle issues but lazy techs will always be lazy (that's a WHOLE other story for another thread and time). While there yesterday, I thoroughly cleaned the entire machine and corrected the mis-stacked paper in tray 4.
So, I told her I would fix the issue with tray 3 so they could use it. This morning, I replaced worn out and 6 year old feed, take-up and separator rollers. Cleaned the one-ways and sanded the shafts. I also replaced the clutches since they looked like they had seen better days. Also, the conveyance roller A00J601111 was worn like they tend to get over time (clearly smooth and smaller diameter). Ran lots of test copies, single and 2-sided from tray 3 without issue. Had the customer run a print job (happened to be 2-sided) to test and on the very first sheet it jammed with 99-01. Message said to load 8 1/2 x 11 plain which is what is loaded and indicated on the machine display. Also, the LCC setting in System 2 is set to 8.5 x 11 for both trays 3 and 4. Deleted the job and immediately ran another 2-sided copy job without any issues.
She was printing a pdf, I think from Edge, which made me cringe because the native application usually works better than a browser. She tried another 2-sided print job from tray 3 and it printed out with 2 sheets of paper but with only print on side 1 of the first page. I'm not allowed to look at or mess with the PC or anything on their network. So, I told her to have her IT take a look at the drivers and make sure are the correct ones and also try from other applications. Sounds to me like something on their end because there would be no way a print job would jam when a copy job won't from the same tray. Right?
The only thing I didn't try and regret not doing is connecting my laptop and see what results I get from it verses their network. I might go back out in a week or 2 and try that if their IT doesn't do or check anything. They aren't using the machine much with this whole pandemic thing going on so she said to give it a couple weeks and go from there.
So, has anyone seen anything like this?
Am I missing anything obvious?
Of course, ZERO help from the service manual.
I did find some info in the Knowledge Base (Solutions) KBA01100536 that mentioned lots of things to try and check, all of which I already did. Of course then it says replace PRCB and if that doesn't fix it, MFPB but it sounds like they are talking about a consistent 99-01, not specifically when printing.
