Cleaning the corona wire
If you are experiencing print quality problems, please clean the corona wire as follows:
1 Open the front cover of the printer.
2 Pull out the drum unit and toner cartridge assembly.
CAUTION
• 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.
• To prevent damage to the printer from static
electricity, do not touch the electrodes shown in
the illustrations.
