3 or 4 series primary feed jamming

[toddanderson]

I have been seeing alot of 3 and 4 series with primary feed jams
J0513 , J0514 , J051x

Feed tires seem to have a short life.

Has anyone else been dealing with these primary feed jams ?

Re: 3 or 4 series primary feed jamming

Not a solution, but something that you can rule out:

J0523, J0524 codes are often caused by slightly low paper lift height.
J0502, J0503 codes are often caused by developer dumping the front cover, then into the paper trays.

If you're not seeing those codes, you can rule it out.

J0511, J0512 are most often caused by incorrectly hard-set paper size, or worn out rollers.

There is a multi feed being detected for the 051x jams. I see this even on new machines so it isn't always the feed tires being worn out.

If it's the paper then these machines are way too sensitive.

The 0523 0524 are prevalent too. If the paper doesn't lift high enough maybe it is running into the right side of the PF-7150 drawer.

We need a definite solution for these jams

This isn't a solution, but showing the customer the importance of putting the paper in the drawer seam side down helps.

Also, showing the customer how to fan the paper after it they pull it out of a ream helps as well.

I have found that if you are getting multifeed jams that the fuser can cause this problem.
Not mentioned in the troubleshooting. Appears to cause the next sheet to catch up with the previous sheet.

Re: 3 or 4 series primary feed jamming

On the 2 & 3 series we had a lot of problems with fusers causing jams but so far none of that on the 4 series

For the tray 1/2/3/4 feed rollers, I find them to be pretty rubbish and usually fit a konica minolta roller to them when they are worn as these last a lot longer and do a better job... part no. A00J563600

Adjust the tension on the spring that engages/disengages the separation roller. I have done this with success at least 2 dozen times in the past few months.

Re: 3 or 4 series primary feed jamming

i have seen the 0523 issue (paper out in try 3 but still try's to feed)in the 4 series Kyocera , replacing the bridge seems to resolve the issue. although i can't find anything wrong with the old bridge unit .

All,

Checking to see if others are still having these issues.

We have been seeing J511 become prevalent in the past 6 months, primarily on 4 series machines but also on 3 series. Kyocera keeps telling us it is paper, which we have definitely seen, and switching to a different paper brand has helped in some cases.

My concerns are that we are seeing it more and more. I agree that these new models seem to be too sensitive to paper quality. In the past, Kyocera's have pretty much fed anything that was loaded in the trays. That doesn't seem to be the case anymore.

We have adjusted the retard roll spring tension and that does help, but we have also found that can create a delay in paper feed that customers notice. It will intermittently slow down the feed of the paper to the point it is very noticeable delay. It will do this after 12-15 pages and then after every 5-10 pages. We noticed this on multiple 4003i/4004i's after adjusting the retard roll spring tension. The customer changes paper type and this becomes even more noticeable. Crazy part is the delay does not cause a jam.

We have also installed the urethane feed rolls and have had mixed results with them. Some machines feed fine, others continue to have jams.

We also have cleaned all feed and drive clutches on most problematic machines with minimal impact.

The best solution we have found is to have the customer switch paper manufacturers. Kyocera help desk says they know of some brands that cause issues, but they are leery about publishing brand names.

Any input as to whether others are seeing and doing is greatly appreciated.

Thanks in advance,

Mike

+1 for this. I have also had the customer load the paper seam side down and fan the paper. It helps a lot.

I also have had the same issue. If they put fresh paper in usually stops this. I found on duplexing the moisture in the paper causes the paper to curl and misses the gate on the second pass to the fuser.

Re: 3 or 4 series primary feed jamming

On boise web sit they say to load their paper seam side up.

Re: 3 or 4 series primary feed jamming

About what side to print first on . Heard a little trick that if you lick your thumb and index finger and press one corner of the piece of paper in between them the side that sticks to the finger is the side to print first .

Re: 3 or 4 series primary feed jamming

Not exactly the same issue but I definitely have been having issues with bad paper. I had a new 4 series machine with 3 different document processors that would either multifeed and skip scanned pages or if it had MF detection it would stop all the time at random. Client kept telling me it was jamming all the time when it was actually just doing its job. The fact that they would print off 200 pages, rearrange a couple and then scan it back in meant that there was ALOT of paper dust accumulating on the separation roller turning it white. "But I dont understand how this is only a problem now when we have been using this paper for years and the other machine doesnt have this issue"
The other machine has a Canon Scanner next to it dedicated to scanning thousands of pages a day.
The paper in question is Office Depot brand. Called the regional out twice and the paper dust was the only common denominator.
Ive been pushing and pushing for them to just use a PDF editor to combine documents, remove pages, and add pages. They claim they have tried but it just took too long when they could do it faster and easier with the paper in their hand.
They fill 3 tall recycle bins a week.
