Supply messages: if the printer reports a non-Konica Minolta supply, press OK or Continue to keep printing. If the cartridge is not recognized, reseat it firmly.

Streaks or faint print: shake the cartridge again and print a few pages. The imaging unit or drum is a separate part with its own life.

Compatible vs. Remanufactured vs. Original

Original (OEM) toner is new from the printer brand and costs the most. Compatible toner, like this cartridge, is newly manufactured by a third party to the original's size and page-yield specifications, so it drops into the same slot at a much lower price. Remanufactured toner is an emptied original cartridge that has been rebuilt and refilled. Castle Ink sells compatible (newly manufactured) toner and remanufactured inkjet cartridges.

Frequently Asked Questions

How many pages does the Konica Minolta TNP50M magenta print?

About 6,000 pages, based on Konica Minolta's rating for the original A0X5334 at roughly 5% coverage.

Can I replace one color at a time?

Yes. Each color is a separate cartridge, so replace only the one that runs out.

Will this void my printer warranty?

No. Under the U.S. Magnuson-Moss Warranty Act, a manufacturer can't void your printer warranty just because you used a third-party or remanufactured supply. If a non-original supply directly caused damage, that specific repair might not be covered.

How long can I store it?

Sealed toner keeps for about two years at room temperature. Keep it in its bag, away from heat and direct sunlight, and store it flat.

When will my order ship?

Orders placed by 4 PM ET, Monday through Friday, ship the same business day from Long Island, NY, by USPS (2–5 business days). Expedited 1–2 day delivery is available at checkout, and shipping is free on orders over $50.
