This one is getting on my nerves. The unit leaves a ghost image on the following copies of any job that uses black color. I have already eliminated the other colors, but the only way to get rid of the ghost is to run about 5 blank copies through to get the residual charge off. I have change the Black IU and swapped the Transfer belt with a good one. Can anyone think of anything I might not have done?
