FS 1135

[still]

I have four FS 1135's doing the same thing. The paper jams coming out of the tray in the paper entrance guide, way before the registration roller. It is putting a small tear or a dimple about three inches in on the left side on the lead edge. I tried a new cassette, and feed section with no luck. Works fine in the manual feed tray. It does not happen every copy. Any suggestions would be appreciated.
Thanks!!

Replace the clutches.

WP_000180.jpgWe replaced all the drive, and all the guides and rollers in the machine feed section and still had the nicking and jamming.
what we did as a test was to install a mylar over the sep assy and the cassette base. hard to see but is in the middle of the image. This stopped the nicking and jamming on the two machines we were having trouble with. One of them has run over 6k with no jams or nicks. I am sending this to our Region Rep so maybe someone in KM can figure out why only some machines have the issue.

Have you tried removing mp tray and making sure there isn't anything in the way like paper or labels?

Need to replace mylars right before registration rollers, bypass section has to be remove to be able to replace.

Hector L is correct, it is a bent mylar guide just before the registration rollers. Easy way to detect this is to leave tray 1 empty and copy/print from tray 2/3. If feeding from Tray 1 does not cause a jam, but feeding from trays 2 or 3 jams then it is definitely a bent mylar guide before the registration roller. The problem is trays 2/3 feed rollers lose contact with the paper before it reaches the registration rollers and there is not enough drive to force the paper past the bent mylar. Tray 1 will work because of the shorter path and the cassette feed rollers assist in forcing the paper past the bent mylar guides.

accessing the reg path is a real pain.

TECH TIP:

for flipped mylars or piece of scrap paper shove the cardboard from a legal pad through the bypass to clear out any obstructions.
