Got a weird problem with an Epson Aculaser c4000. Essentially it seems to be leaking blue/cyan toner onto the right hand side of any page that it prints. The leakage isn't constant and looks different on each page, so I don't think there is something on one of the rollers or anything.
I've swapped the fuser and the toner cartridge but things haven't improved.
Anyone seen this before, how did you resolve it?
