Page 265: Reference Materials Data
KX-FLB852CX / KX-FLB852CXS 8 REFERENCE MATERIALS DATA 8.1. PRINTING OPERATION PRINCIPLE 8.1.1. PROCESS CHART AND PROCESS BIAS 8.1.2. CHARGING Charging is the stage that keeps the surface of the sensitive drum a fixed electric potential. The sensitive drum is the Organic Photo Conductor (OPC), which is a electric conductive cylinder whose surface is covered with the Charge Generation Transfer Layer (CGTL).
Page 266 KX-FLB852CX / KX-FLB852CXS 8.1.3. EXPOSING When the drum which is charged with the fixed electric charge is irradiated by the laser beam, the plus charge and minus charge are generated at the Charge Generation Transfer Layer. Passing through the Charge Generation Transfer Layer which conducts the minus charge, the plus-charged drum´s surface is neutralized to be skipped.
Page 267 KX-FLB852CX / KX-FLB852CXS 8.1.5. DEVELOPING AND TRANSCRIPTION The developing is the stage that the OPC drum with an invisible image is changed to visible by the toner. The drum unit consists of mixing paddle, toner supply roller, developing roller, developing blade, charge wire, grid plate and OPC drum. The bias voltage is added to the developing roller and toner supply roller.
Page 268 KX-FLB852CX / KX-FLB852CXS 8.1.6. CLEANING OF TRANSFER ROLLER The toner attached to the surface of the OPC drum is transferred to the paper at the transcription stage, but a part of the toner remains. The cleaning is the stage that cleans the remain toner after the transcription stage. The remain toner on the drum and the toner which was attached to the place where the laser beam didn´t scan are gathered to the developing roller to be used again.
Page 269 KX-FLB852CX / KX-FLB852CXS 8.1.7. FIXING On the process of the transfer, the transferred toner is weakly attached on the paper. Fixing means the process to fix the toner on the paper permanently. The fixing part melts the toner at the high temperature using the halogen heater. The toner is fixed on the paper by the heat and pressure through the fixing part with the image.
