The drum unit in Sharp copiers forms the electrostatic image and transfers toner to paper. Drum diameter typically ranges from 30 to 80 mm, and length from 240 to 320 mm. The drum surface is made of aluminum alloy with OPC or silicon photosensitive coating. Light sensitivity is tuned to the 400–700 nm range. The service life of the drum unit is between 50,000 and 120,000 pages. Drum rotation speed is synchronized with the main motor within ±2 percent accuracy to ensure uniform imaging.
Structurally, the drum unit includes a photosensitive cylinder, a central shaft with anti-wear bearings, a cleaning blade, and a waste toner container. The blade is made of durable polyurethane to remove excess toner efficiently. The primary charging system applies 500 to 800 volts for uniform surface charging. Modular design enables fast installation and replacement. This structure increases image sharpness, reduces spots, and ensures full compatibility with genuine Sharp toner.You can order and buy drum unit from Iran by contacting us through whatsaap and email.

Impact of Drum Units on Toner and Print Quality in iran
The drum unit plays a key role in transferring toner to paper and creating the final image. The drum’s photoconductor surface must be smooth and sensitive to ensure uniform toner adhesion and proper fixation. A worn or damaged drum causes lines, shadows, smudges, or faded prints and increases toner consumption. A healthy drum ensures precise toner distribution, reduces material waste, and improves image detail clarity. Maintaining and using an original drum unit significantly enhances print quality and extends device lifespan.
