A jam code would be really helpful. =^..^=

Re: KM5050 jams halfway out of fuser

Admittedly I don’t see these very often, and the ones I had ran so well I didn’t encounter many problems.
that being said I have one with just over a million copies that started jamming with the paper halfway out of the fuser, in other words the lead edge of the paper is about 4 inches out of the top of the fuser.

I suspect it is in the process of turning the paper to go into the finisher so I have disconnected the finisher and have the pages exiting into the copier now and it does not jam this way.

Is there something in that area above the fuser that goes bad to cause jams before exiting to the finisher?

Of course this is intermittent so I am not seeing an obviously broken part as of now.

Thanks for any words of wisdom.

If you look at the paper exit assembly just above the fuser I suspect you will see a large amount of a "brown substance" [paper dust] adhering to the swing gates and other surfaces. After a while it becomes thick enough that the paper cannot smoothly pass through and causes random jams sometimes and continuous jams at other times. You could remove the assembly and thoroughly clean it, but this will only last for a few months. The real solutions is to replace the entire assembly. Just retired a 5050 a couple of months ago that had 3.2 mil on the clock and we had replaced this assembly three times for this problem, it was the only fail-safe resolution as the vaporized paper dust gets into everything, the guides, the swing gates, the bushings. Hope this helps.

There's a post on the upper door that breaks so it doesn't assist the exit gate enough. Usually the front one. If I recall one orientation will work, one won't. (portrait, landscape)

You might check that the finisher mates at the right height and doesn't tend to pull the left door open. You'll see J85 & J87 codes in this situation.

thanks, would this be the exit assembly you are referring to: 302GR93134

That is the old number [rev. 2] current order number would be 302KS94320.

An electrical noise-no, chattering on one occasion but very, very briefly.

Re: KM5050 jams halfway out of fuser

Still no jam code?

I have not been back to the customer since I disconnected the finisher and I personally wasn’t able to duplicate the jam, but the customer had texted me a picture of the jam so I could see it located.

It is at a CPA office and at this time of year they are using the heck out of it so when it was jamming consistently for what they said was 30 minutes I just needed to do something to keep them running.

I was able to see the pages in their recycle bin of all the ones that had jammed and they all looked similar where you could see it looked like it stopped halfway through the fuser as opposed to accordion type jams.

If I get back and it jams for me I will definitely make note of the jam code.

Re: KM5050 jams halfway out of fuser

If you pull out the top section above the fuser, there should be a one way bearing that is starting to slip when it reverses to feed the paper towards the finisher. Usually you can just clean and lube the shaft to fix it for awhile. (if I were to tell that to somebody on fb, I'd probably get kicked off for a few days.)

Replaced the paper exit assembly today so we should know in couple of days of heavy use of that was it.
Thanks everyone for the input on this.

finally got to see the jam code and it was J 94.
looks like it should be the finisher entrance guide or sensor.

Re: KM5050 jams halfway out of fuser

And what kind of finisher? DF-710, DF-720 or DF-730? =^..^=
