dsm730 devloper stiking to drum

[moderntech]

machine gets great copies but is getting dev. on the drum and causing the copies to be sandy feeling. i have replaced the dev unit and entire pcu section including drum. did a memmory clear and checked drum ground. changed transfer roller and checked all settings in sp data with no luck any suggestions..

When the drum is attracting developer, it means the charge roller voltage is too high.

You can also try to adjust SP2210

What kind of memory clear did you perform?
