BEFORE USING THE MACHINE►MAINTENANCE

When the laser unit inside the machine becomes dirty, line patterns (colored lines) may form in the printed image.

• Colored lines always appear in the same place. (The lines are never black.)
• Colored lines appear in parallel with the direction of paper feeding.
• Colored lines appear not only on output from a copier but also on prints from a computer. (The same lines appear on 

both copies and print jobs.)

If conditions similar to the above occur, clean the laser unit as explained below.

Press the release buttons on the sides of the waste toner 
box inward and pull out slowly.

The cleaning tool is attached to the front cover.

If the cleaner is dirty, remove the cleaner from the cleaning 
tool and replace it with a clean one. For the procedure for 
replacing the cleaner, see steps 5 through 7.  If the cleaner 
is not dirty, go to step 8.

Replacement cleaners are stored on the waste toner box.
Grasp the end of the cleaner and pull it out of the waste 
toner box.

 Put the removed cleaner back on the waste toner box.

Cleaner

Be sure to point the cleaner down.
Labels similar to (A) are attached to areas that require 
cleaning.

Pull the cleaning tool out until you feel the tip of the tool 
leave the cleaning surface of the laser unit.

The laser unit is cleaned in four locations, including the 
location cleaned in step 8. Clean all holes.
