I have a Laserjet 4100n that is only used for jobs sheets and printed text. Recently all the text on every page has become 'ghosted' i.e. it's like having "double vision" when reading it. I know it has something to do with EP drum or the developer.
A new cartridge doesn't solve the problem and I've cleaned every roller I can see.
Will a maintenance kit, which includes a fuser unit, solve the problem?
However, for not much more money I could buy a whole new printer.
I've lowered resolution, created cleaning pages, slowed the speed of printing, checked for humidity & moisture, printed a completely black page before each job.
Any help, or a fix, would be greatly appreciated.
