BizHub C451
The BizHub C451 is a high-volume Konica Minolta color MFP on the TN-611 toner platform (TN-611K black, TN-611C/M/Y colors) — cartridges built for heavy departmental color. Research flagged the key correction: TN-611, not TN-310, for the C451/C550/C650 line. Our compatible TN-611K/C/M/Y cartridges are verified for this family.

Frequently Asked Questions
What toner family does the BizHub C451 use?
The C451 uses the TN-611 CMYK family — TN-611C, TN-611M, TN-611Y, and TN-611K. Each color is a separate cartridge replaced on its own schedule.
Does the BizHub C451 share its TN-611 with the C550?
Yes, the C451 and C550 use the identical TN-611 set. Offices with both models can consolidate spares.
Why does the C451's magenta seem to empty faster than cyan and yellow?
Individual color consumption follows your actual document mix — magenta-heavy branding or photos will drain TN-611M first. It reflects your content, not a machine fault.
