Hi there, faded print is normally caused by a drum unit, but could also be the fuser. For your machine, the drums are built into the toner cartridges so you would have to replace the toner first to rule that out. If replacing the toner doesn't work, it could then be due to the fuser unit. Please can you get in touch with our customer care team at
