KM-8030 J62 jam code

[Jimbo1]

Who else is having trouble with J62 jam codes on these machines. We hvae some that are doing it out of the box and don't catch it till it hits customer site then of course it's a real problem. Tech hasn't been able to isolate what is causing it.


Looking for someone strong in the ways of the Force here!!

We had a few of these on our in-house machine this morning. The user was feeding 65 lb. paper stock from tray #1. It pulled from tray #1 OK, but wouldn't invert for face-down delivery. I looked for a face-up output setting in the driver (which may have solved the problem) but no such luck. The heavy paper stock would flip the leading rear corner going into the duplex tray almost every time, and stall at DUPFSW.

My solution was to print the job on the CS-C4035E from the bypass (heavy paper), and output to the top tray face-down (doesn't have to invert). It fed the 300 no problem. I don't suppose that helps you very much.

You might consider a paper weight issue though...

=^..^=

Well I will check but I believe it's pretty much standard 20-22 lb paper that is being used.

There used to be J60 too but he has done some work and replaced a few things.

Will get back.

Meantime anybody else gots ideas???????

make sure that white wheel that is on the solenoid in the duplex unit is spinning freely.

I had this problem a while back with a 8030, nothing would solve the jamming problem until I read on another forum about adjusting the fuser speed to -20 in simulation (U053). The machine has now made over 500,000 copies without the problem returning. Hope this helps.

[Jimbo1]

Well he tried changing 53 and that seemed to make it worse.

Any other ideas???

[Hose1cook]

The only other thing that I do on all of these models is to reposition the Gate Solenoid on the front of the transport section. I remove it and screw it back in the lower screw hole so you get maximum throw out of it.

I tried to wide the gap of the stay reverse feed assembly.

Unscrew the unit and place a piece of tape (+/-1mm) on the rear and the front side of the unit, on the exit side of the machine so that the unit tilts over to the right side.

I tried it already with a few machines and so far so good.

check the duplex roller. Also Ive had the jumbo sep roller units not fitted correctly

[vinnyb]

Check your power.
I had two with the same problem and one was fixed by replacing the refeed roller in the duplex, the othe had low power problems.

[just a tech]

We had one that would constantly jam with a j-65 and we tried all kinds of things. was fixed when we replaced the guide plate ass'y. (kyocera calls it a "stay reverse feed".. the part # is 302FB19331) turns out that it was warped a little so it was causing intermediate jamming problems. After replacement, the damn thing ran a 15,000 page duplex copy job without one jam. hope it helps. might or might not but it couldn't hurt..lol

I had some luck (so far) with a 6030 by cleaning the Feedshift Solenoid and Duplex Switchback Solenoid. The shafts can get gunky.

Try setting U263 to FACE-UP (MEMORY) for the DP. This will prevent documents fed from the DP from entering the duplex unit. It will finish scanning originals prior to begining copy output. U331 is copy output from the glass, default I beleive is already face up.
Another thing I've done is file smooth the slot where the pin from the solonoid rides in the eject roller in the duplex unit. It has a tendancy to dent because of the soft Jap metal used and cause the solonoid to drag slightly. There was a firmware update that was suppossed to give a little more time out delay for that reason but I noticed no difference. Yes the solonoid gets gunked up.

The dulpex eject roller would be a good choice to replace but they have been on back order.

The J62 codes seemed to have appeared all of a sudden on my machines out of the blue. Some had 200k copies, some had 1 million. Go figure.

jam

KM6030/8030: “Jamming in Fuser/Switchback Area” .Check eject feed
pressure. Remove 302FB20710 (Upper Cover A Fuser Eject).This cover warps
and prevents positive feed pressure between the upper and lower fuser eject
rollers. Modify or replace as necessary.

Thanks a lot for your knowledge ! I done it on my TA DC 2080, and i solved the problem, i also modified fusing speed, and changed duplex roller
