Compatible Magenta Drum Unit

The SuppliesMax KNMA7U40TDM is a new aftermarket drum unit built for Konica Minolta bizhub C258, C368, C458, C558 and C658 printers. It delivers magenta output for business and personal printing at up to 75000 pages measured at five percent coverage. The unit is manufactured in ISO 9001 and ISO 14001 certified facilities using new and recycled components to meet OEM standards.

Replaces OEM A7U40TDM and DR-313M

This drum replaces the Konica Minolta A7U40TDM and DR-313M original parts as well as Katun KAT49812M and KAT55316M equivalents. It is sold individually so buyers only need to swap the magenta drum when its life ends. The jump is worth it when colour quality fades or the printer signals a drum replacement, restoring crisp contrast without replacing toner cartridges that still have supply.

Fits 110V U.S. bizhub models

Designed for 110V machines sold in the U.S., the unit installs directly into the compatible bizhub models without additional tools. Using a compatible drum does not void the printer manufacturer warranty. It frees the budget from higher-priced OEM drums while keeping the same page yield and colour consistency for high-volume colour workflows.
