OPC drum stands for Organic Photoconductor drum. It is a critical component of a laser printer or photocopier that is responsible for transferring toner onto the paper to produce a printed image.

The OPC drum is a cylindrical drum made of a light-sensitive material that is coated with a layer of photoconductive particles. When the drum is exposed to light, the particles become conductive, allowing them to hold an electrostatic charge.

During the printing process, the OPC drum is first negatively charged, and then a laser beam is used to selectively discharge areas of the drum that correspond to the image that needs to be printed. The discharged areas attract toner particles, which are then transferred to the paper and fused in place using heat.

OPC drums have a limited lifespan and need to be replaced periodically. The frequency of replacement depends on the type and volume of printing and the quality of the drum itself.
