These issues have been caused by a cracked or broken "Rotation Shaft Assembly". I've done 3 or 4. p/n a4f3r70b11Originally Posted by blackcat4866
Basically there are two lower paddles in addition to the two upper paddles that knock down the paper. Here we're talking about the lower paddles.
two hints
1) there are 2 extra clips on the assembly you're removing to use when you drop one.
2) a dab of grease always helps c-clips defy gravity.
The flippy arms are brand new, just changed. The front one was cracked at the shaft.
I did fix it, though, to my great surprise.
I have two of these side by side, so I got my keyop to set up an offset job on each machine, then I would sit and watch each machine to see the differences. I tried fajdoooo's trick of setting up the ruler to hang at the leading edge. I noticed that when I set up the ruler to overlap the top of the stack by 6mm, the top-of-the-stack height changed considerably. I expected some variation, but not 15mm or more.
Then I noticed that the grippers that tap the top of the stack were coming up short of touching the paper stack by 6mm or more. Also I noticed that the upper limit sensor LED1 was at the top of the slot at the front, and PS14 was at the bottom of the slot at the rear and bottomed out in it's adjustment.
When I raised the PS14 at the rear by 8mm, then both the front and back (sender and receiver) were even at the top of the slot in the cover. The dangling ruler detected variation of ~6mm, and the grippers tapped the paper stack every time. As a consequence the offset stack is perfectly even and true.
I believe the wild variation in height means that the side tappers are sometimes not touching the side of the stack, and the grippers are not keeping the stack steady, letting static move the paper around. As a side benefit, we're no longer getting the message "The tray is full. Please remove the paper from the tray." after only 300 or 400 pages, sometimes less. And when you do need to remove the paper, the message clears, which it didn't do before. I believed that it had something to do with the sensor in the center of the elevator tray, but in truth, it's the relationship between PS14 elevator tray upper limit, and PS46 near tray empty sensor. Essentially when the elevator tray is empty and lifting, PS46 and PS14 must trip about at the same time.
I hope that helps somebody. I sure did a lot of head scratching over this one. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Well done BlackCat and thank you for the solution!

Firmwares HERE.OK Google! ... will I need Berrocca this morning?
There is stack settings that needs to be completed on setup and when a FS is changed.
Whatever
Just checked the manual. The finisher adjustment is very comprehensive. it's possible to adjust for both main and sub scan misalignment. I was warned about this problem in training.
Whatever
probably the gripper /lw [1] is broken

bachirabouzeid: That's already been changed/new.
Apparently that's not the whole deal. Back today.
You must have a different manual, allan, because I could not find a single mention of the main tray height adjustment.
I have identified another difference between my two finishers. Left MFP, after every 3 or 4 pages moves down/up/down/up. Just a few mm, but consistently. Right MFP, after every 3 or 4 pages moves down (but not up), leaving an ever increasing gap between the top of the stack and the grippers.
The finisher has had a controller, firmware, LED1, PS14, and the photointerrupter for that center flag. There just aren't any other components involved, so there must be some adjustment I haven't got right.
I don't know if I can upload a .mov file. Lets give it a try.
Nope. The forum won't take that file type. Send a PM if you'd like to see the little movie. =^..^=

Yes you are right it's only for FD and CD. The tray height should be controlled by position sensors only.
Maybe change the 2 finishers. If the problem says with the machine...
Whatever
How did you make out here?
Swapped finishers. The problem follows the finisher. One of our other techs is replacing the static eliminators, but personally I don't see how that will improve the tray movement/tray height, which IMHO is the main issue. We've started the long drawn out process of getting KM to take a look at this issue. =^..^=
