Step 7: Cleaning
The final step in the laser printer image formation process is the cleaning stage. During the cleaning stage, any lin-
gering toner residue that was left on the OPC Drum needs to be cleaned off before the next image can be created. 
Since this toner cannot be reused, a Cleaning Blade is used to remove the residue from the OPC Drum and deposit 
it into the Waste Toner Box.
