What is OPC drum?

OPC (organic photoconductor) drum is a critical component of printer or copier that impacts the image printing performance.

How does OPC drum work?

STEP 1: The PCR charges the OPC Drum to the correct electrical properties, usually a negative charge. Step 2: The laser from the printer writes the image to be printed to the OPC Drum, discharging the electrical properties on the drum. Step 3: The Developer Roller adds the toner to the OPC Drum.

When should I change my OPC drum?

Separate drum units last quite a bit longer than a toner cartridge and typically should be replaced after the use of 3-4 toners. Your printer should inform you when it’s time to replace the drum, but you can usually tell your drum is on it’s last legs if you start to see black spots or lines across the page.
