①
Charging
• Conductive Roller charging
• Applied voltage : -1.1kV
• Charge acceptance : -520V
• OPC coating thickness : 21um
• OPC diameter : Φ60mm
• 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 box
by auger and belt driving mechanism
②
Exposing
• One polygon motor ( 6 facet )
• Single beam LD (1ea)
• LD wavelength : 785nm
• Polygon motor rpm : 29685
• LSU energy : 0.25uJ/cm^2
• OPC exposed potential : -50V
1. Exposing is implemented by laser striking on to OPC with uniform potential
2. Laser beam is modulated according to image to be printed that is from PC
3. Latent Image is formed on OPC, which is developed with toner
③
Developing
• Non-magnetic, mono component
• Non-contact development
• Developing bias : DC + AC
• AC peak to peak : 1.5 ~ 2.0kV
• Roller diameter : Φ10mm
• Process speed ratio : 1.2 (OPC=1.0)
• Color order : Y -> M -> C -> K
1. Only latent image formed by exposing process is developed with toner
2. AC + DC Voltage is being used to develop toner into latent image on OPC because non-contact
developing method is adopted
3. Y, M, C, and K Images are sequentially developed onto OPC and transferred onto Intermediate Transfer
Belt (hereafter ITB) to form a color image on ITB
4. Toner Bottles are used to supply toner into developer compartment
5. Toner level is being sensed to control toner supply from toner bottle to developer
