Price:  $33.48
Product Description
Konica BizHub 421 Toner Cartridge - 32,200 Pages

This Toner Cartridge prints 32200 pages with an average 5% page coverage. The amount of pages can vary depending upon the amount of ink printed onto each page. (5% page coverage is a standard Konica Minolta specification)

This product comes with a 6 month Warranty against any defects (including free replacement). We stand behind our products 100%, as these are not manufactured by Konica Minolta.

Why toner? Why not call it ink? Regular ink dries quickly, which is why cartridges for inkjet printers do not last long. Laser Printers use toner, which is ink in the form of powder. A sealed toner cartridge can be stored for 2+ years prior to usage.
