Toner dusting badly after 50,000 copies/prints. (replaced developer, blade, brush, filters cleaned development sleeve, replaced potential sensor) Any idea??

run 3-001 to initialize id sensor
I'd also look up the tech pub D131-008 from the MP 7502 regarding toner dusting. It had some SP modes to change that really helped.Comment

There is a bulletin on the MP 6002 or 6001 that mentioned a crap paper and low coverage would make the DV puke like crazy. Something Something bycarbonate and the toner would loose it's charge ability and no longer stick to the DV and just floats in the DV unit until its thrown out.Evil will always triumph because good is dumb.Comment

I would pull the hopper off the dev unit and check the seal running along the bottom of the toner inlet plate (the metal plate with the tiny holes) The seal adhesive detaches from the plate allowing toner to dump into the DV unit. I've seen this on the first 300K PM on some machines. This causes dark copies, light copies, dirty copies... Replace the hopper (D2233210)and put new developer in it. Don't try replacing the seal. You'd really need a jig to get it on correctly.Comment

I usually use reliable developers for machines that work a lot.
Of the reliable developers, I use type 27 for mp 5500,6000,6001,9002.... for all series , and the Konica Minolta DV-011 developer.
The average life of these developers is about 1,500,000 copiesComment
