Hi guys,
Does anyone encounter this problem before?
Once user send print job to machine like 600 pages non stop, print quality getting lighter.
At first I suspect toner supply doesn't work so I check hooper behind and check toner path to developer, make sure nothing is not blocking and also the same time clean up hooper.
When same problem arise, I change the T/S block and replace a (used) better drum and developer unit. It seem ok but after some time , problem come back again.
Anyone can advise?
