Intermittently jamming with J013 & J014. See picture. New feed belt & DFPR, cleaned all rubber and sensors. I swapped the whole document feeder and still the same results! Pictures show where it's jamming and what paper looks like.

Re: MPc5502a SPDF jamming
Might be a long shot, but have you replaced the separation roller and torque limiter in the ADF? -
Re: MPc5502a SPDF jamming
Reverse roller has more bite than the feed belt. Some type of slippage on the drive for the feed belt. Could be the belt slipping on the drive roller or the one way bearing in the drive roller or the shaft it is on. On some DF that shaft is also driven by a one way bearing in the drive train, I have had to replace those in the past.Comment

Re: MPc5502a SPDF jamming
I tried ruffing up the end of the shaft and the one way bearing in the drive roller with emory cloth and it still had issues pulling in the original. I think I will try and find a whole new feed section again to see what happens. I'm totally frustrated with this! I've had another MPC5501a doing the exact same thing and swapped that doc feed as well to no avail. 4 doc feeders with the same issue and only SPDF's????? Coincidence maybe.
It has been very humid and wet here in VA lately and telling both law firms with these copiers that their documents are damp will not go over well.

Re: MPc5502a SPDF jamming
check this bulletin out for the MP6503, it could apply to your particular issue, since it is the same SPDFComment

Re: MPc5502a SPDF jamming
I know this is a few months old, but was a solution ever found to this issue ? I've had exactly this issue a few times now, as per photos, always on the 4501A feeders and it me drove nuts. Had one today, and I think I've found the cause.Comment

Re: MPc5502a SPDF jamming
Replaced three things..... Steel Feed shaft(has all the feed components on it), one way feed roller(white one) and one way feed drive shaft. So far so good!Comment

Re: MPc5502a SPDF jamming
Pretty common issue in heavily used adf's in my experience. But you eliminated that as a suggestion with your original post, because you said that you replaced the entire feeder and it did the same thing, and then later that you'd tried the same thing on another machine with no results.
Are we to assume that the DF's that you swapped had the exact SAME issue?Comment

Re: MPc5502a SPDF jamming
Oops! I forgot this is what I'm installing when I run into this for regular jamming. However, for this issue the problem turned out to be the 100yr old house it was in that was causing the intermittent jamming. Installed Smart Power Regulator to resolve. I don't know why i didn't think of it sooner. It's been running perfectly since.Comment

Re: MPc5502a SPDF jamming
I found that the plastic guide plate bows slightly upwards (red arrow direction). You can see a fair amount of bowing/springyness when pushing down with your finger at that point. This results in the metal strip at the base of that separation rubber to be a higher level than plate A, and the paper catching the metal strip sometimes, resulting in exactly the situation in the OP's photo. To test this I placed a couple of paper wedges at the points of the green arrows to push the guide plate downwards, and no jams there whatsoever. The only thing is at the point (black arrow) where the guide plate then contacts the separation roller and torque limiter (especially that little plug at the side of the limiter), I had to file down a bit to maintain a gap, beware of that, but it seemed to work. Is it a different type of plastic on those guide plates/DF's that warps easier, should there be another screw to hold it down at that point, is that a part that needs replacing ?, I don't know, but that explains the fold on the paper at the point and subsequent jams. I hope this helps.
