Compatible Drum Unit DR-313K for KM (A7U40RD) (Black) by DrTusz is a reliable choice when you want your Konica Minolta laser device to keep producing crisp, clean pages without streaks or fading. Dear Customer, we designed this compatible drum unit to deliver the same quality as the original, while keeping everyday printing costs under control.
A drum unit is the heart of the imaging process in a laser printer: it transfers the toner image onto the paper with precision. Unlike a toner cartridge, it does not contain toner—its role is to keep every line sharp and every filled area evenly covered. With an impressive yield of up to 90,000 pages (at 5% coverage), DR-313K is made for busy offices where consistency matters as much as speed.
We also make sure your parcel is carefully protected before transport, so the drum arrives ready for installation and smooth operation. Looking to complete your setup? Under “Related products” you’ll find matching toners in black and colour, waste toner tanks, and other drum unit variants—handy when you want to refresh the whole printing system at once.

Toner cartridges bearing the DrTusz logo are made from high-quality, specially selected, and tested components available on the market.They ensure high print quality, comparable to that achieved with original toner cartridges.
Toner replacements offer real savings; they are significantly cheaper than originals and often have a higher capacity, allowing you to print more pages from a single cartridge. High-quality compatible toners deliver crisp, long-lasting prints and work seamlessly with your printer, so you pay less without compromising on the final result.
Additionally, our compatible toner cartridges are covered by the “Gold Warranty” program, which provides coverage for the entire lifespan of the cartridge. Its key advantage is a quick, hassle-free, and effective claims process.
