I have a 951 which every 100 to 200k copies coats the drum carriage with toner causing white and dark areas when the charge corona and LED get dirty.
It seems to be over toning, with the toner misting out of the cleaner unit & then on to the corona etc.
The machine is in a warehouse and only prints A4 invoices which are low coverage. It can print 8k in one night shift so it's a busy machine. It has done this a few times and each time the drum & dev are changed. It's ok for a while, then it does it again. I've carried out adjustments in the KM troubleshooting guide and its on the latest firmware but it still does it.
Has anyone heard about or seen anything like this?
Any thoughts would be appreciated.
