Found a new reason the machine would give J-2101 that and J-3111(skew sensor jam).
If tray 1 and 2's feed tires are done it makes a dent in the paper that would catch under the drum.
Had that jam while i was working on a machine next to it it would jam every 100 pages or so.
Changed the feed tires and the problem was gone more than 10000 pages printed!
Whatever
What kind of usable life do you get from the standard rollers? The stated yield is 500K, but about 300K is about all I can expect. The orange neoprene rollers seem to wear more slowly. The problem is that there are more jams, even when brand new. I won't be installing any more of the orange rollers. And if you add the pickup weights you'll get less than 200K, and the rollers wear unevenly.
Thanks for the information. =^..^=
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Those big grey ones? A4EUR714## ?
Got more than the yield. 500K + that assembly does feel a bit flimsy?
I changed them on a total page count of 12M and a feed count of 8M for the first time.
Have to say the wear looked minimal and even. I compared the old ones to the new ones while changing them out.
Every thing one these machines goes well past.
Got the air suction feed units on there PF-703 that thing is rock solid, so tray 1 and 2 shares only a little of the load.
The orange ones would do about 250K from my experience the ones on the B423?
I always change all 3 at the same time but its then only the separation roller that was badly worn out.
Those grey ribbed pick up tires works really well i leave them on there for a second time.
The B601 machine roller would do 250K+.

Ok, I am going to give this a try. We have changed transfer voltage for the tray already and adjusted the solenoid position at the same time about 6 weeks ago. It runs well and then occasionally (sometimes after thousands of copies) it will do it again. And it only does it on 8 1/2 x 11 paper. Any larger sizes and it works perfectly. I am guessing the extra weight from the longer sheet is enough to pull it off the drum. Whatever is wrong is just barely wrong. I'll post the results of this. Feels like KMinolta should address this a little better.
KM does have a lot of write-ups for this problem. This guide has been helpful for me (particularly the last page): https://www.dropbox.com/s/tn7v8wcm45...ollow.pdf?dl=0
I am also having these issues with a 1052 and I believe these adjustments will work, but the problem I have is that all of my high voltage adjustments are grayed out. Does anyone know where to turn them on? I'm sure it is a DIPSW, but I don't have time to look at every one until I find it.
Just throwing this out there but HV is modified by the machine depending on humidity. Check or replace the sensors if they report 0% humidity. IIRC the 950 had a thermistor below the transfer/sep unit. Replacing that thermistor fixed some weird cq/codes. It's a shot in the dark but maybe due to that sensor the machine thinks it has to lower the separation voltage.
