Drum Unit Iran

drum unit

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.

The drum unit in Ricoh Aficio copiers forms the electrostatic image and transfers toner precisely onto paper. Drum diameter typically ranges from 24 to 30 mm and length from 240 to 330 mm. The drum surface is made of aluminum with OPC or amorphous silicon coating for high light sensitivity. The surface charging voltage is set between –600 and –800 volts. The service life of the drum unit ranges from 70,000 to 160,000 standard prints.

Structurally, the drum unit includes the drum cylinder, a central shaft with anti wear bearings, a charge roller, and a cleaning blade. The cleaning blade is made of durable polyurethane to remove excess toner without damaging the drum. The modular design allows fast installation and replacement without special tools. This structure ensures uniform image quality and reduced print noise. The unit is fully compatible with original Ricoh Aficio toner.

drum unit

The separation pad in Canon copiers separates and feeds paper from the tray to the printing unit. Its length ranges from 50 to 100 mm, and width from 10 to 20 mm. Made of wear- and heat-resistant rubber with high friction, it prevents paper jams and double feeds. The installation angle and pressure are typically 5 to 10 degrees with a force of 0.5 to 1.5 N. The pad can handle 50,000 to 100,000 feed cycles without performance loss. Its surface is resistant to toner and humidity, increasing durability.

Structurally, the pad includes a base body, friction rubber, and quick-mount clips or screws. It moves synchronously with the feed roller, transferring one sheet at a time. Installation and replacement are fast and require no specialized tools. This design ensures precise paper feeding, prevents misalignment, reduces print stops, and is compatible with standard Canon paper types.
