Clean the inside of the printer (scanner window) as follows:

1. Turn off the power switch, and then unplug the power cord.

    

   There are high voltage electrodes inside the printer. Before cleaning the printer, make sure you have turned off the power switch and unplugged the power cord from the outlet.

   

2. Press the Cover Release Button, and then open the Front Cover.

    

3. Pull the Drum Unit Assembly out of the printer.

    

   Handle the drum unit carefully since it contains toner. If toner spills on your hands or cloths, wipe or wash it off immediately with water.

   We recommend you put the drum unit on a piece of disposable paper or cloth in case you accidentally spill the toner.

4. Gently wipe the scanner window with a soft dry cloth.

    

   

   After you have just used the printer, some internal parts of the printer are extremely HOT! When you open the covers of the printer, never touch the shaded parts shown in the following illustrations.

   
   • DO NOT touch the scanner window with your fingers.
   • DO NOT wipe the scanner window with isopropyl alcohol.

5. Put the drum unit back into the printer. Close the Front Cover.

    

6. Plug in the power cord, and then turn on the power switch.
