| OPC is short for Organic Photoconductor, which means light-sensitive drum. OPC drum is a kind of photoelectric conversion device by using OPC material coated on the surface of conductive aluminum cylinder. Its characteristic is that it is an insulator in the dark place, which can maintain a certain static charge. When the light of a certain wavelength irradiates, it becomes a conductor and releases the charge through the aluminum base to form the electrostatic potential image. Drum core prone to failure 1. Poor electrical performance of the organic layer of the drum core will lead to "printing dust"; 2. Poor electrical performance of the organic layer of the drum core will lead to "print ghosting"; 3. "hard injury" of organic layer of drum core will appear "regular horizontal line"; 4. When the drum core printing life arrives, the printing shadow will appear gradually; 5. "grape channeling" type printing defect may appear due to poor drum core conductivity; 6. Poor drum core conductivity (circuit breaker) will print "white board" without text image; 7. The printing words will be blurred if the drum core gear is loose; 8. Poor surface lubrication of the drum cartridge will lead to drum cartridge motionless. Maintenance of drum core 1. Do not touch the surface of the OPC drum with your hands; 2. Do not use chemical reagents (such as alcohol) to wipe the surface of the OPC drum; 3. Do not hit the OPC drum surface with a hard object; 4. Be careful not to bring staples and other office supplies into the printer with the printing medium; 5. Remove the toner cartridge or OPC drum from the machine and place away from light, preferably covered with a newspaper or other object. If there are scratches on the surface of the drum core, there will be black marks on the paper. 6. Use even, fine and high-quality toner, because poor quality toner will damage the drum core. | ||||
