This machine had big varying reg that often was off so far it also had jams (j20 and j11). The problems existed from drawers 1, 2, and MPT. After disassembling the paper guides, cleaning rollers, inspecting mylars, servicing clutches, swapping clutches and upgrading firmware, I still have varying reg, although about 3/4" now and the jams seem to have stopped. So I must have messed around near the problem, but at the moment I really am not sure. With servicing first, then swapping the reg clutch, that shouldn't be it, or could it? The count is 42K and this happens from print, fax, and copy. Any thoughts appreciated. Dave
PS. these beauties are a real bear to disassemble.

I've had something similar. The registration would be off quite abit, shifting the image towards the top of the first page only, then the second, third, fourth and so on appeared to shift back down the the proper location on the page. Since this customer makes mainly a single copy at any one time I was able to adjust it so that that first page was moved down to the proper location on that page. I've been planning on returning to this copier and do more trouble shooting, starting first with a firmware reflash and going over the feed system. It seems strange that it only shifts the first page and not the rest, I can't pin this on the retard roller for sure.

So you're referring to the separation roller in the paper feed drawer? I'm getting the problem from all 3 paper sources. I guess all 3 could have too much drag, which makes me think maybe it's the reg roller that lacks enough pressure to overcome the drag from the retard rollers. Anyone buying???

KMA recommends replacing the springs on the reg roller if you need to remove them, because they can get stretched out. We tried that along with clutches, PCB, mylars, paper and firmware. Someone even suggested a drum unit. None of those helped. We had an account with 9 machines doing this and nothing we tried helped. We had more success addressing the retard (separation) roller in the cassettes along with the guide. remember they changed the retard guide on the FS-3900 series? Additional cassettes had the same problem. The only consistant source was the MP tray, so that kind of rules out alot of the stuff we tried.
DaveH: You could have multiple problems and you fixed one and now need to adress the second. Try the retard roller, modify the guide and stretch the spring.
elheather: the problem we had was not just on the first sheet. It was on multiple copies also.
You did not mention, by how much your registration is moving, if it does not shift for more then 5mm then, the problem will be in mylars ( 2) – just before the reg roller. Second item you need to check is a spring on separation roller and gray plastic that surrounds it ( in the cassette) – I’ve seen a few when tech removed it and it wasn’t inserted back in properly – not seating flash with the rest of the tray. If discrepancy in registration is more then 5mm ( when you print status page and top of it is cut off ) then most likely it is dr-130. Most often it is mylars either bent or missing ( removed by a previous tech). I’ve made some spares for myself – using double sided sticky tape and clear plastic form binders.

At first it was off enough to jam, like 40-80mm, but now after messing with so many things it's closer to 10mm

You may be dealing with 2 or more separate issues >> start with mylars, then check the cover around separation roller. Once I had a machine with label stuck underneath the cover – just b4 the reg roller and until I’ve taken the cover off completely and upside down – could not see it, it was catching the paper with its sticky side and causing slow feed. I had a few of those machines with a clutch failing on 20k, do not mess around with those clutches, just replace the dr-130
My apologies for the confusion. This machines are based on fs-1300 printer >> in fs-1300 drive unit is dr-130 in fs-1128mfp is DR-150 – part n# 302H493040
I hope you're not in a rush. When we checked last Wed. they were on back order. About 28 of them on back order. Interesting! I wonder if there may be a problem with the DR-150? Gene
Proximity to stupidity is exhausting!

The cust has a brand new "loaner". This bad boy has taken up residence on my desk.

I think its a knee jerk reaction to order parts when not needed. I tried the drive unit on 5 machines that I had registration problems with and it was not the problem. I even swapped the drive unit with a working unit. Retard roller, guide and stretched spring took care of it.

I agree about the knee jerk part, I actually thought it hadn't been ordered, but found that it had.
Have you or anyone replaced the reg roller itself? It looks to be smaller surface area than the full rollers of other models. That's on order too.

We had an 1128(25k prints) that was misregistering from all trays.I removed the clutch pack(DR-150 – part # 302H493040)disassembled and cleaned the clutches.The registration clutch was filthy and one of the collars was worn.Once reassembled(a project in itself) and re-installed it still misregistered but less.The problem was resolved after replacing the DR-150.

That is what I did too, and I had the same result. I'm just waiting now for the DR-150

If by "it" you are referring to the reg roller, it is a mess, if you're talking about the DR-150, it is too. By about the 3rd or 4th time you'll still hate it, but you'll probably start to hate it quicker
I replace the reg roller and mylars today...didn't help. DR-150 on BO till 9/30
