Kyocera Mita Toner Cartridges

Kyocera release 1M page Yield drumKyocera Corporation have just announced the availability of its KYOCERA Mega Surface Series amorphous silicon (a-Si) photoreceptor drum, which offers record durability as a core component in electrophotographic printing equipment — including laser printers and multifunctional products (MFPs). The A4-sized a-Si drum is now available for shipment to equipment manufacturers worldwide.

The new product represents an industry first in successfully employing a hard amorphous carbon (a-C) thin-film to form the drum’s surface-protecting outer layer. In Kyocera’s own testing, this development makes it possible for a single A4 drum to print approximately one million sheets — more than triple the life of Kyocera’s conventional A4 a-Si photoreceptor drum, which was already the industry’s most durable, with a lifespan estimated by Kyocera to be approximately 300,000 A4-sized sheets.

Additionally, Kyocera’s rigorous internal testing is designed to yield conservative durability estimates. Third-party testing of Kyocera’s A3-sized imaging equipment has demonstrated 2.5-million-page durability with no drum replacement. The new series represents the first a-Si drum in the A4 class to demonstrate million-print durability using Kyocera’s own extreme test parameters.

Electrophotographic printing involves transferring toner (powdered ink) from a photoreceptor drum onto paper. Over time, friction created by the paper eventually wears away the drum’s photoconductive surface, necessitating periodic replacement of this component. Since drum wear increases in proportion to printing speed and volume, a more durable, longer-lasting drum can offer compelling benefits.

With the new series, by evenly forming a hard amorphous carbon (a-C) thin-film on the surface of the drum using Kyocera’s proprietary thin-film formation technology, the company has succeeded in increasing drum hardness five-fold compared to its conventional products*4. The improved wear resistance has enabled Kyocera to more than triple the current industry record for A4 print drum durability, from approximately 300,000 to one million sheets of A4-sized paper. This enhanced durability can significantly reduce the frequency of drum replacement, thereby minimizing waste, environmental impact and the user’s “total cost of ownership.”
