We have a TA-5003i, 80k on the unit, with an AK-7110 and a DF-7110 that gives random 0511 jams, paper makes it to the middle of the bridge unit when jammed. When the paper is running A3 (8.5 x 11), the paper stops in the AK-7110 (Bridge unit), but if we change the paper orientation to A4 (8.5 x11R) machine runs with no jams. Here is what we have done to try resolve the issue, 1) swap out AK-7110 and DF-7110- same issue, 2) swap out fuser unit- same issue 3) swap out feed units- same issue. The service manual shows the 0511 jam to be located in the V section which I am assuming is the exit/ turnover unit area where the registration sensor is located which was cleaned. Anyone run into this issue on this series?

Re: TA-5003i 0511 random jam on A3 orientation
Well A3 is closest to 11x17.... US Letter is closest to A4. Sure it's not just a size mismatch error? If not, check out this thread: AK-7110 Jamming -
Re: TA-5003i 0511 random jam on A3 orientation
The registration sensor is below the secondary transfer roller, under the fusing unit. The sensor is staying active too long. Have you tried feeding letter out of the other trays or MPT ? I would guess feed drive unit could use replaced if everything else seems ok.
Could be a clutch slipping, but there's more leeway for letter-r.Comment

Re: TA-5003i 0511 random jam on A3 orientation
1st. Is the machine set to auto detect the paper size or is it set to LTRr in the system menu. Either way what size is indicated on the event log vs what is actually in cassette? I had one the other day set to auto detect and the lever on the underside of the cassette was not attached causing it to register some other size than actual.
2nd. I almost always loosen the spring on the separation assemblies. Loosening it actually puts more pressure between the feed and separation rollers.Comment

One thing you may want to try is putting some oil on the pivots of the two white plastic arms on the Separation assembly, also if you check the black plastic part the Separation roller is on, the part that rub against the bigger white arm may have a "lip" on it, I have found filing off this lip helps. Have been successful with doing this to fix a lot of feed problems.
Also did come across one the other day where the clutch on the end of the Separation roller was not doing its job even though it appeared okay.Comment

Has Kyocera had any technical bulletins concerning this issue?Comment

Re: TA-5003i 0511 random jam on A3 orientation
Just to make sure, You are putting A3/letter paper into the machine correct? If you're putting in A4 paper then the machine should be set or detect A4 paper.
Is it auto detecting in Inch or in Metric? Needs to be the same as what the machine is set to use depending on its location. If its set to metric it can mess it up.
If the white arm that moves the Retard roller doesnt move back and forth very well it can cause jams as the tension spring wears out.Comment

Re: TA-5003i 0511 random jam on A3 orientation
It's autodetecting in inch. We have ordered all new pick up/feed/ and sep assemblies and I believe that white arm is part of that. We went out to one of the mfp's that we were having issues with 0511 jams and reducing the spring tension on the sep assembly seems to have stopped the 0511 jam issues, but was only able to run a ream of paper though it, so time will tell.Comment

Adjusting the separation spring seems to have done the trick. We also installed new p/u, feed and sep rollers as well, but the jamming stopped with the spring pressure adjustment.Comment
