SP5210dn -misfeeding

[sandmanmac]

I'm at my wit's end on this one.
This unit has only about 50K.
It has legal size paper in tray 2, and there is no moving it to tray 1 for convoluted reasons I won't try to explain.
Tray 1 will run all day without issue, but tray 2 (legal) jams randomly to quite frequently.
Sometimes it will pass 50 pages or more without issue, and then it will start jamming every few pages, then run ok for many more.
I have swapped paper feed rollers (including swapping the rubber over from a 2027 hub, which I heard could help), sep pads, drawers, and even the entire paper feed unit.
I've tried Thick and thin settings, I've installed the spacer at the end fence. I've removed the mylar from the vertical feed that's installed on then "health care" model (which this was at one time), and I've blown out the inside in case a sensor was dirty.
Nothing has made a difference.
I feel like there's probably something simple that I'm just missing now that I'm so frustrated
The jam code is always 53, and there is 1 page halfway into the fuser, and ther other page is just starting to feed up.

Anyone else experienced this and have some advice for me before my head explodes?

Re: SP5210dn -misfeeding

and you have checked tray settings on the machine vs the PC right?

Re: SP5210dn -misfeeding

If you're asking me if the tray is set to legal size, Yes.
Also, the driver is set to auto tray select and document is Legal size.
I've also tried both the automatic and manual paper size settings
The machine is also currently out of customer's office and back at my shop (and doing the exact same thing) while I try to figure out a solution.
They print almost entirely on Pre-printed paper from this tray, which I had convinced myself was the problem - even though their other HP printer has no issue with it, but I've been testing it with plain Legal paper at my shop, and it does the same thing.
Frustrating!

Isn't there a sensor in the frame where the paper from T2 passes on it's way up through T1? I think I remember having to clean/replace/reseat that sensor before. Take a look at that.

Re: SP5210dn -misfeeding

The preprinted paper uses a drying agent like tac power but thats not the problem. The spring that push the friction pad up needs to be stretch a little.I had the same problem running the water bills at an utility district. Mongo

Re: SP5210dn -misfeeding

I was optimistic about trying the tips that I got, but today was filled with even more frustration. No Joy

I tried another paper tray unit (3rd in total). Same problem.
I decided to fire up another printer that I have at my shop thinking that I'll give them that one if I have to, but tray 2 jams lagal paper on that one too!
But wait, it gets better - Letter size paper will run all day from either tray!

As I stated up front, for reasons to ridiculous to explain, they have to use Tray 2 for their legal paper, so swapping them around is not an option, so I've not yet tried legal paper in Tray 1 to see the results, but just for fun (sarcasm), I plan on doing that tomorrow

Re: SP5210dn -misfeeding

Took a look on TSRC for that machine and there are SEVERAL bulletins for jamming. They all seem to be for no feed jams, but I wouldn't be surprised if the solutions might help you. Had to add one to imgur because the file was too big. Might be worth looking at.

Though since you said you've swapped out option trays it might be the sensor that detects paper feed in from the option tray has gone bad or has a bad harness.

Thanks for these, but I've seen them all and made the necessary fixes where required.
And I can't imagine it being a sensor or harness from option tray because, like I say, I've tried 3 different ones - and another entire printer.
So, I'm wondering if there's any chance it's a F/W issue, even though I've not seen any documentation to indicate it, but I don't have priviliges to access it, and try.
I feel like I've exhausted everything other option. Extremely frustrating

I took a look through the FW history for the machine and didn't see any jam related updates, there were very few to begin with. Perhaps the machine side of the connector that connects the option tray is damaged?

Thanks for looking. I have all those notes to and didn't see anyhting myself. I'm just grasping at straws at this point.

Here's the latest:
Firmware Updated: No difference
Yet another printer acquired to test: Does EXACTLY the same thing!
Tray 1 tested with Legal paper: Runs FLAWLESSLY
Additional Tray 3 Added (just for fun!): Tray 3 Misfeeds too!

I mentioned it before, but all trays will run Letter size paper all day long.
It's definitely caused by a sensor in the Unit remaining on, because the next sheet is feeding in before it should be. But why EVERY tray/ machine that i have? And why only legal size paper?
I've now tried 3 different printers, and no less than 4 different tray units!

From the manual:

Code

Description

LCD Display

53

PFU1 / 2 tray, Front cover

1st optional tray sensor does not turn off.

A1, Y1

I mentioned earlier that Legal paper had to be run in Tray 2, but that's not exactly correct, it's actually that Tray 1 must contain letter size paper -and put simply, that's because they are incredibly set in their ways, they run a couple of programs that don't acknowledge the presence of more than a single paper tray, their IT/server, everything is in California, they're are all very old, and change does not come easy. My hands are pretty much tied
I've decided to take them an additional Tray 1 that I've set for legal size paper, and they can swap it in when they want to run their pre-printed stuff, which is typically only a few times a week (I think).
I'm all out of ideas.

If anyone elase has one of these lying around (and nothing better to do), I'd love to know what happens in your case, if you run 50 legal size pages from tray 2?

Beer me. I'm done.

Re: SP5210dn -misfeeding

because the next sheet is feeding in before it should be. But why EVERY tray/ machine that i have? And why only legal size paper?

It's a long shot but reminds of a problem years ago with SCM estat model 55 and 111 called chain feeding. Static would build up as the paper was fed. There was no problem with letter size, but with legal, enough static would build between sheets to cause enough cling that the inch or so of the first sheet would drag the next sheet partially out of the tray. If this is what is happens either the lead edge of the second sheet will reach the feed sensor while still being pulled by the static between sheets or will be far enough out that when it goes to feed, it reaches the feed sensor too soon. Either situation will generate a trail edge jam indication.
