Unlike most other aftermarket companies, Katun is actively involved in product development and testing of its photoreceptors. Extensive tests in Katun's state-of-the-art Research and Development Laboratory ensure optimum electrical and dimensional characteristics. In addition, in-machine tests are conducted over the drum's full actual life, under conditions simulating real-world usage as closely as possible.

Katun offers a wide variety of OPC drums for use in Canon, Konica Minolta, Kyocera Mita, Panasonic, Ricoh, Sharp, Toshiba and other copiers
