KM-520i Jam code 61

[Jimbo1]

We have a km-520i brand new at a customer location that has been giving jam code 61 Went out the other day and swapped the middle feed section with on from a Falcon III. Did so much better(one jam out of nealy 200 duplexed and stapled prints) that I left it in and we ordered a new unit that we could warranty.
Another tech took it out and put it in and has been there all day dealing with the jam.

Anybody seen it and any ideas?

Now we have run codes 21 and 24....taken the entire left door assy. and duplexer out there. Awaiting results. Still wondering if anyone else has seen this?

Sorry jimbo. I've not seen this. =^..^=

Well I am happy to report we found the problem. The lower clutch in the verticle transport was dirty. In a brand new machine. Looked like it had 300000 on it.

Quality control. Wonderful stuff.

Oh and the replacement unit is backordered. Surprised?

we've got a machine with this problem.

Its a 420i, j61 intermittently. Visual inspection found nothing wrong. Hand tested the switch, I've gotta say I dont like'em. The logic state doesnt change immediately but with delay.

not resolved atm.

The one I looked at was giving me J81 and J52 jams. The upper vertical clutch had one too many shims on the gear side. So did the duplex clutch.
The gear side of the clutch should spin freely when not engaged, and both were a smidge too snug. Jamming supposedly happened only the first print of the day. I had a dozen consecutive jams before getting to the clutches. =^..^=

We have remedied many J61 calls by using 2 springs instead of just one on the white idler rollers on vertical feed. Also use F3 paper switch spacers on the F4 vertical switches and lastly have had to replace vertical feed clutches on a few repeat offenders. Be sure to upgrade main firmware to Ver 7 and Options to Ver 1.12

I have come to the conclusion that Kyocera is Japanese for "backordered". Any questions.

Wasnt there suppose to be a permanent fix on the panels? The spacers was thought to be a temp solution.

Do you have falcon4's that dont have this modified or updated panel? If its updated, were they still giving you j61/j21?

There's suddenly a surge of these jam codes, thought I dig a bit more here.

I found that the spacers correct J22's, doubling vertical idler roller springs and vertical clutches correct J61's...should do it all while there!

[jmaister]

one'd think that once a part is updated on the last generation machine, the updates carry over.

I've checked the manuals, the panels look the same lol. How can this kinda thing happen?
