6.1 Composition
Key Name Function/system
[1]
Cleaning Blade • Scrapes residual toner off the surface of the Photo
Conductor
[2]
Grid Mesh • Evens out the charge deposited from the Electrode to
make the surface potential uniform throughout the sur-
face of the Photo Conductor
• The grid voltage is applied to the Grid Mesh
[3]
Electrode • DC comb electrode Scorotron system
• Using the comb electrode ensures that the charge is
concentrated on the grid mesh, thus reducing the
amount of ozone produced
• The charge corona voltage is applied
• Maintenance free; no cleaning mechanism is available
[4]
Charge Corona • Deposits a charge to the surface of the Photo
Conductor
• DC comb electrode Scorotron system
[5]
Toner Collecting Screw • Conveys the waste toner scraped off by the Cleaning
Blade into the Waste Toner Storage Tank
• Screw type
[6]
Waste Toner Storage Tank • Stores waste toner of each color
• Fixed type; requires no service jobs, including disposi-
tion of the stored waste toner
• The storage tanks for Y, M, and C are of the same
shape, while that for K is larger than others to accom-
modate a greater amount of waste toner
