Thanks for all the info....I will try it..
clean magneticroller
hai.
i also have this problem but i not replace dev o drum coz still not due only service.i filter the dev and some cases i change mag roller.this method i also used in mp3590/4590 dark,blur & uneven copies.
I just put the latest development unit D0092301 in a machine today so we'll see how long it lasts.
Am interested to see how long the machine works with the new developer unit, hopefully, you replaced the charge roller at the same time. Definitely check the continuity of the drum earth shaft as have had a number of these fail (D009-1111), in addition check the continuity though the charge roller electrode plate connection assembly at the rear frame side (connection between parts D009-2317 and D009-2318), this will exhibit as SC304 or as very high values for the charge roller (up around 2000v) and may have no continuity when checked with a meter.

I'm really curious if this is going to be the long awaited solution. So far there's no TB beside the MB wich is referring to the new DV unit and "allows" us to undo the SP modifications wich makes the machines lighter.
But 100k without trouble isn't indeed that bad for this POS
I guess we had the inside track on these - we've been getting them in as a sub for the original part number for almost 2 months. It does seem to help, but not nearly enough. It seems to extend the period of nausea about 50% before the machine actually barfs, but it's not the 200% improvement needed to bring the machine back to spec.
