Genuine Sharp Drum Unit MX-40NUSA

This genuine Sharp drum unit carries part number MX-40NUSA and fits the MX-3050N, MX-3070N, MX-3550N, MX-3570N, MX-4050N and MX-4070N multifunction printers. It is sold as a single unit with a colour identification seal for each toner station.

Installation and common issues

The unit slides into the designated drum slot and locks with the printer’s built-in lever; no tools are required. Errors typically appear when the colour seal is left in place or when the unit is not fully seated, causing the machine to report a drum mismatch.

Who this suits and who should look elsewhere

Offices running any of the listed Sharp models that need a factory-rated drum rated for 200000 black pages and 150000 colour pages will match the original specifications. Buyers with different Sharp hardware or those needing a separate toner supply should look elsewhere.
