Almost every 650 and 7255/7272 I have or had ,dumped toner like there's no tomorrow. There is small plastic jig that konica sent for free that sets the angle of the mag roller. They also sent us new dust collectors to replace the ones at point 9 on the horiz transport, the logic being that too much paper dust was getting into the recycled toner. I found most of the mag rollers were out of adjustment and the jig helped a lot but not all. If you have over 1,000,000 copies you may want to change the dv box.

No, it's only our dealership who's had this problem!!!

NO, you must be wrong, I was told we were the only dealership that has those "crazy" issues. I assumed they made that mod kit and jig just for us.

I've also had a few where the T/S assembly needed replaced, even after a new developer unit was installed. You would think a TD sensor is mandatory for mid-high speed machines.

And i was told it's only dealers in the UK that get this problem

Thanks for the responses on another note what I have also seen is that on the toner recycle unit, is that toner gets liked packed and starts to back up real bad to the point that big blotches of toner fall on the paper from the recycle/cleaning blade assembly

Oh yeah I forgot to tell you about that. It will happen a lot if your weather is humid like N.C. Best to remove the drum and clean that area each time you have the drum carriage out. But it's not as bad as the 470/550 machines, the auger will pop out and nic the drum. You have been warned!!

[Jr Garza]

Yes Sir, thats what it looks like humid toner,,, guess that there's no options on that one huh!!!! just vacum the hell out of it would you know if the new DV units are much better than the old/originals in adj. wise???

If you are talking about buying a new box for your problem machine, I would not count on the factory to have made the adjustment for you. I would get the jig to check the gap on the mag roller. Another thing to watch for is the smallest gear on the back of the dv box to strip, and that will cause the box to not pull toner to the mag roller. Check these gears each time you pull the box out. When they strip the cust. will complain of light copies. When you pull the dv unit you will see the toner backing out of where it is suposed to go in, cause the machine keeps calling for toner. If you rebuild the box then change the bushings also. Sloppy bushings will cause the gear to strip. Good Luck!

Could've avoided that pesky and recurring problem by putting in a TD sensor.

That sure looks like a KonicaMinolta Di2010 to me. At first, I thought it was a BH200.

This model is particular about how you tell it there is a new PC. Going from my less than perfect memory, go into service mode, counter, PM and reset the IU counter to 0, turn off the machine, replace the PC and developer/starter, reinstall and turn it on, go back to service mode and do function F8.
