M2640dw jamming from tray 1

[copiertec]

Copier has less then 10k on it and it jams from tray 1. Feed/separation/p/u rollers look good. The client had knocked the separation roller assembly spring out of place/ we put the spring back in place and now the machine will jam sporadically out of tray 1, it could run 50 with no issues, then jam on a 10 page run. It runs fine out of the bypass tray. I'm wondering if reducing/ adding separation spring tension could resolve the issue. Has there been a tech bulletin about this issue?

What's the jam code ?

What's the jam code ?

I'll pull up a jam code list on it tomorrow, I had it with my printouts but it accidently got tossed with the rest of the paper.

could be the feed clutch from your explanation, not related to the spring.
Have had jamming from cass 1 on out of the box system...
rusted clutch

We had a case with an ECOSYS M3655 that seems a lot like this. Randomly would fail and randomly just start working again, making you think you fixed it.
As it turned out there was a bushing, white is this case, missing from the inside of the shaft the cassette feed clutch rides on.
Right out of the box it worked well for the first 8-10k and then started to flake out randomly.
I know it's not the same model as the one you are working on but maybe you have a similar situation.

Maybe there's an issue with the paper. Please try loading a brand new ream of paper into Tray 1. It's worth excluding at least one potential reason. btw an Event log printout would be useful

The majority of the jams (26) are Jam4211 which is in the fuser area. I see there have been serval fuser updates and this one seems noisy when it's running so we are going to order an updated fuser unit and a feed clutch for tray 1.

I will look into it.

I have to wonder what the test page looks like. If it is okay for the first half and poor on the second half you have a fuser issue.

I noticed smudges down toward the second half of the paper, I was not sure if that was drum related, but you have confirmed my uncertainty.

The J4211 is def. the fusing unit as well as the smudges. You may need a fuser drive unit also. It will start making a gear growl. It's relatively easy to get to from the bottom side of the machine. I don't think you'll need the clutch.
We keep those fusers in stock. They don't last very long at all.
