KM5050 jams from drawer 2 only

[copyaction]

KM5050 with 2.6 million pages groans then jams in multiple copy from drawer 2.
Replaced feed rollers in both drawers.
Swapped #1 feed unit into #2 and problem remained.
There are 2 pages stuck when it jams, 1 halfway out the fuser and 1 can be accessed from lower left jam door.

Try swapping paper cassette too. Do sym 903 and check jam codes

Thanks, have they been known to make a groaning noise when misfeeding?

It would help to know a jam code. Without that, I can only make a random guess. =^..^=

I am going back tomorrow, I will check jam code.

Inspect middle feed unit gear train for sideways deviation, gear skipping.

I had thought about that, but it did not jam a single time from drawer one.

There is a black feed guide on the vertical conveying unit just below feed where unit 2 paper comes out that can have the tabs break off the edges. It is worth checking to see if they are missing. It too can cause pretty consistent misfeeds.

Whenever I can, I print out (or look at) the error/jam log of a machine. One can quickly get some insight into the jamming problem a machine is having.

It also allows me to see if the customer is blatantly lying about a problem.

Not often, but it does happen.

Update, went back with paper drawer 2, feed clutch, black plastic feed guide inside lower jam door.
None of those resolved it.
Cleared jam counter, got it to jam again with jam04 and jam21.
Still not a single jam from drawer 1.

CS-3050, 4050, 5050 Falcon III

Misfeeds (Jam J21) misfeeds from tray #3, ledger size. (21.03.0C.01.03) Inadequate pressure on left side door idler rollers. Install two add'l pressure springs at lower vertical path idler rollers in left middle door.

That's what I've got in the database. =^..^=

IIRC it may be the engine PWB. A bad lift unit would take out the engine board on these models. It was really the only problem they had.

I have seen that in the past but the paper in drawer 2 is lifting and only seems to jam on multiple copies.
