Replacing the drum unit 5
Important
• While removing the drum unit, handle it carefully because it may contain toner. If toner scatters on your
hands or clothes, immediately wipe or wash it off with cold water.
• Every time you replace the drum unit, clean the inside of the machine. (See Cleaning and Checking the
machine uu page 110.)
When you replace the drum unit with a new one, you need to reset the drum counter by completing the
following steps:
a Make sure that the machine is turned on. Leave the machine for at least 10 minutes to cool down.
b Press the front cover release button and then open the front cover.
c Take out the drum unit and toner cartridge assembly.
