Cleaning the corona wire 4
If you have print quality problems, clean the corona wire as follows:
a Open the front cover and leave the machine for at least 10 minutes to cool down.
b Take out the drum unit and toner cartridge assembly.
IMPORTANT
• We recommend that you put 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 machine from static electricity, DO NOT touch the electrodes shown in the
illustration.
