Applied voltage : -1.1kV
Charge acceptance : -520V
OPC coating thickness : 21um
OPC diameter : 60mm
Non eraser system
1. Organic Photoconductor is charged to uniform voltage by conductive roll charging method
2. No ozone is produced because corona is not used
3. Charger roll is cleaned with cleaning roll
4. Toner remained on OPC after T1 process is cleaned by cleaning blade and retrieved into waste toner
