KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.3. PRINTING OPERATION PRINCIPLE 15.3.1. PROCESS CHART AND PROCESS BIAS 15.3.2. 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 245 KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.3.3. 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 246 KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.3.5. 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 247 KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.3.6. 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 248 KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.3.7. 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.

PREPARATION • PbF (: Pb free) Solder • Soldering Iron Tip Temperature of 662°F ± 50°F (350°C ± 10°C) Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil.

KX-FLB802CX/KX-FLB812CX/KX-FLB802CXS/KX-FLB812CXS 15.6. DIGITAL BOARD SECTION When the unit fails to boot up the system, take the troubleshooting procedures very carefully. It may have a serious problem. The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.) The first step is to check the power source.
