Re: C950 Print Defect

I've ordered an OEM toner for the customer. It'll be in today or tomorrow. Update to come soon. Thanks everyone

Re: C950 Print Defect

Update:

We put the new lexmark toner in the printer and ran about 150 pages of black and grey print. The problem became less visible but, was still there. The black drum was then swapped out for another black drum (which did not solve the problem before and the marks went completely away).

So my conclusion is the drum and developer were both contaminated/ damaged by the compatible toner.

Thanks everyone for your help. We can call this one closed for now!
