What are OPC Drums? Leave a comment

Inside each toner cartridge are many components that work together to deliver your prints. 

The OPC Drum is probably the most recognizable component inside toner cartridges. Its important job is to receive the image to print from a laser inside the printer and then transfer the image or text to paper.

An OPC Drum has many layers to help it interact with the other components in a cartridge. 

The OPC Drum has many layers of substrate.

The layers must all work together to do a very specific job in three steps:

The PCR charges the OPC Drum to the correct electrical properties, usually a negative charge.

Then the laser from the printer writes the image to be printed to the OPC Drum, discharging the electrical properties on the drum.

The Developer Roller then adds the toner to the OPC Drum. The toner is only attracted to the discharged areas.

Each OPC Drum is tested for its charge ability, sometimes referred to as sensitivity. This determines how much toner will attract to the drum. The less sensitive the drum is, the less toner it will attract, resulting in lighter prints.
