3 or 4 series primary feed jamming

Re: 3 or 4 series primary feed jamming

Good morning everyone, I have a Taskalfa 2554 which often causes jams 0511, the photocopier has 40,000 pages, the jam only occurs in the A4 drawer, even by reversing the paper pick up assembly the problem recurs, if I set the paper from A4 to A4R the machine does not it jams, I think it's a clutch timing problem, Kyocera doesn't help, I can't resolve the problem on a nearly new machine, has this happened to anyone?

Make sure your firmware is up to date, I know they have addressed some issues in firmware to help with the jamming.

Back last year we were having lots and lots of these jams, usually not long after changing feed tyre sets (genuine, Katun sets were fine..), one of my colleagues pulled the slipper clutch on the retard roller (genuine) degreased it as best he could and the problems went.

We started doing that as a matter of course when changing feed sets and had no more of these jams with genuine feed sets, Katun ones were still until recently flat spotting badly/early on the retard roller but seem fine now.

Figured I would provide an update to the machine we had the J511's on.

Since we provided them a case of Hammermill paper on 4-2, the machine ran through the entire case with no J511 jams and has continued to run with only J512 jams. The customer uses previously printed paper in tray 2 so we pretty much disregard tray 2 jams. Here is a screenshot of the history from KFS:

We have seen changing paper solve jamming issues on many machines that had high jam counts. ?

I still believe Kyocera needs to address their feed systems. They used to be absolutely bulletproof and would run anything. That doesn't seem to be the case anymore.

When the xx52ci and xxx2i lines first came out our tech rep said to oil ALL the points in the feed ports that pivot and move. Been doing that ever since. FT get around 100k, plan on replacing them if you are on site. If your sep roller is getting a flat spot in it replace the entire assy, they are only ~$60 because something isn't moving correctly. Only had to do that a handful of times. Dealing with schools and student paper drives some paper definitely runs better than others but ease of replacing these helps and we get all 4 seasons from static in the winter to humid summers. Just my 2 cents

Yeah I've taken to using my SuperLube on all of those spots just about every time I visit a machine. I used to change the spring pressure but the lubrication seems to be more consistent

Check QA O083 that was released last month with an updated spring.

Back when the xxx0 series was midway through production, we got a call from a long time customer. We were told the machine stinks. It was literally giving off a smell. When I arrived, sure enough there was a bad smell in the room where the 4550ci was located. I made a few prints (I always print a status page and event log when I walk up to a machine if I can) and as the pages printed out, the smell became stronger. It seem to be coming from the fuser unit. I pulled the fuser unit to let it cool so I could inspect it closer. As I was looking at the event log, I noticed a smell like that from the fuser. On a whim, I pulled open the paper drawer and took out a 3/4" stack of paper. I put it up to my face and took a good whiff. That smell was there. I fanned the paper in front of my face, the smell was there. I looked over and sure enough the customer was using some no-name paper.

I left the fuser out and told the customer I would be right back and the machine would be down until I returned. I ran back to the office (less than 1/2 a mile away) and grabbed up two reams of good paper. When I returned I noticed the smell had almost gone away. I put the fuser back into the machine and put one of the reams I brought into the first drawer. I then ran a full set of reports. As it ran the Maintenance report, there was a little smell, but it quickly decreased. I ran another set of reports, no smell. It was the stinky no-name paper.

I then got a hold of the key operator and explained what I had found and what I had done. I ran a Maintenance report and there was no smell. He was skeptical so I had him take a good whiff of his paper. He still wasn't convinced, so I put his paper back into the machine. I ran a Maintenance report and as it was running the smell came back strong. He was now convinced. He had me put back the paper I brought. From then on I noticed that customer always used a brand paper.

I had always had been a bit indifferent when it came to the subject of paper run in these dry toner machines. This episode taught me, paper DOES makes a difference. Period.

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

Huh, really? Are you swapping the hubs out or just using the whole KM roller? We're finding the KM rollers aren't lasting to life either but they might be better than Kyocera's. Depending on the cost it may be worth further investigation.
