If you are experiencing print quality problems, please clean the corona wire as follows:
a
Open the front cover of the printer.
b
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.
