Hi, Was out of phone reception today so i couldn't reply. Did you check for anything obstructing the paper path or any marks on the lead edge of the paper. The feed clutch can sometimes fail on those KD's which have the extra cassette.

Hi Mic,
Thanks once agian for your kind attention, Well i think its the Clutch..i tried everything else but not the clutch those paper transport rollers are turning both ways. So i doubt theres a faulty clutch. So today i will give a try and let you know...Ok..
Thanks loads.,,,

This is the clutch I fitted to solve a similar issue 6LA47907000 (feed/transport clutch) you could also try swapping feed units to make sure its not the feed unit itself.

If I read you right it's jamming coming out of the LCF, There are 2 clutches in the back of the feed assembly, one for the feed, one for the vertical transport. You can take the back cover off the back and view their operation, if you don't mind lying on the floor. Both are the same part. I have had quite a few fail in the past, though not recently. It is possible to pull them apart,clean them and reassemble successfuly often. The part is 6LE93488000 MAGNETIC CLT.

If you take the back cover off the bottom unit of the machine behind where cassette 3 sits. The clutch sits behind the tray lift gear box.
I can't remember exactly how to get to the clutch as it has been a while since I replaced one myself. Might need to take more bits off to gain access to it.hope that helps though

I am still assuming by the 3rd tray you mean the optional LCF. That is not the one in your photo. If so an acrobatic technician can lie on the floor behind the machine, and remove the rear cover. You can see the two clutches behind the plate just behind the feed assembly. (on the left looking from the back) remove the motor assembly and the two plastic clips on the rear of the clutch shafts. Unplug the two clutch connectors, remove the two screws from the plate and remove the plate while pushing in the shafts for the clutches. Otherwise all the parts will fall on the floor and it willl take you ages to put them back. I then use a screwdriver to hold the clutch shaft in while I pull the clutch off - See previous sentence. It is then possible to carefully pry off the brass ring from the end with the gear on and clean out the magnetic ring. We have had them with rust on. If you do that - when you reassemble them it is a good idea to keep the marks on the ring on the outside and in line with the flat. It makes it easier to reassemble.

Hi

I removed all the clutches replaced with working ones, a small wheel with needle razors(Turning one direction only), all sensors and actuators, PFP tray main motor, PCB Tray module. Still the same fault. I hope it;s something to do with diagnostic adjustments or values... I really need support on this........

Please advise if I'm understanding the situation correctly. You have an eS351c with 2 paper trays and a LCF (KD1012). Paper feeding from the LCF jams at the door to tray 2 with an E320 error. and have replaced the clutches in the LCF and also the drive motor. Is that correct??? If so there are 2 things I would still be looking at the first would be LCF door I have seen it where the spring pressure on the idler wheels in the door was too low, and vertical feed was bad. When that happens there are usually 3 skid marks on the back of the paper that line up with the rollers. On these we just removed that door, removed the cover over the idler rollers and stretched the springs. That fixed it. Another problem I have had is with the small gears in the feed assembly that takes the drive from the feed roller to provide drive for the separator roller. It is possible to remove all the drive assembly from a LCF without lifting the machine. First - please confirm that we are on the same page with the problem though.

Basically the EStudio 351C comes with 1 & 2 trays on it. 3 & 4 trays will be optional (known as PFP) anyway in my system i got the 3rd tray. As u advised i have already checked the spring tension on the door drive rollers, and I have already changed the small gear which will rotate the whole mechanism to one direction. THose rollers are all good. Its seems like a logic problem rather than a mechanical fault. Please advise me are there any codes to advance the paper travel timings so it will touch the rollers in advance.

procedure 4.pdfHandbook section.pdfprocedure 4.pdfIn your first post you used the term LCF and that has confused me all along. You obviously have a paper feed pedestal with only 1 tray fitted. 0-5 448 is the adjustment for PFP upper drawer. There are 4 different adjustments depending on the paper size. I'll try to attach instructions but I've never done it before.

I think I've attached them twice. That was a new experience.
