How can I clean the corona wire of the drum unit?
Do NOT use any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.
If you are experiencing print quality problems, please clean the corona wire as follows:
-
Open the front cover of the printer.
-
Pull out the drum unit and toner cartridge assembly.
- We recommend that you place the drum unit and toner cartridge assembly on a piece of disposable paper or cloth in case you accidentally spill or scatter toner.
