Why offices choose the bizhub C4051i
The fastest A4 colour MFP in the range — built for departments running steady daily volumes that don’t need the size or cost of an A3 machine.
Keeps up with a busier floor
40 pages a minute in both colour and mono, first page out in under 5 seconds, and an 80-sheet dual-scan feeder that captures both sides in one pass — built for departments that have outgrown a slower A4 machine.
Certified for compliance-conscious offices
ISO 15408 Common Criteria certification, TLS 1.2/1.3, AES 256 drive encryption and up to 1,000 user accounts with Active Directory support — with optional Bitdefender® real-time virus scanning on the device itself.
Store, recall, reprint
Secure box storage for up to 3,000 documents or 10,000 pages — public, personal or group — so frequently printed brochures, forms and pricelists are one tap away instead of a fresh print job every time.
The machine
What the bizhub C4051i does
Driverless direct print of PDF, DOCX, XLSX, PPTX, JPEG, TIFF, PS and PCL. A smart job queue skips jobs that can’t run instead of stalling everything behind them. One Universal Printer Driver across the whole fleet.
Scan
Up to 45 images per minute simplex, 90 duplex — scan to email, SMB, FTP, SFTP, Box, USB, WebDAV or a URL, with Scan-to-Me / Scan-to-Home pulled straight from Active Directory and searchable PDF/DOCX output available.
Copy, fax & store
Group, sort and offline stapling for finishing, plus box storage for documents you print repeatedly. Optional Super G3 fax with forwarding to email or an SMB folder instead of printing incoming faxes.
Print from anywhere, anytime
Straight from a phone or tablet — no cables, no workarounds.

bizhub C4051i — common questions
How much does the Konica Minolta bizhub C4051i cost in South Africa?
Pricing depends on your monthly print volume and whether you lease or buy outright. We quote both side by side so you can compare the total cost over the contract term. Send us your monthly page count and we’ll come back with a firm figure.
Can I lease the bizhub C4051i instead of buying it?
Yes — most of our customers lease, with the machine, toner and servicing bundled into a single monthly cost. We’ll quote lease and purchase side by side so you can compare the total cost over the term rather than just the upfront number.
What size office is the bizhub C4051i built for?
It’s aimed at busier A4-only departments that have outgrown a smaller machine but don’t need A3. At 40 ppm with an 80-sheet dual-scan feeder and box storage for repeat documents, it comfortably covers a medium-sized office running steady daily volumes.
Who services the copier after installation?
We do. KM Direct Holdings sells and services everything we supply, with our own technicians in Gauteng and the Western Cape backed by a nationwide network. The person who quotes you is accountable for the machine afterwards — there’s no hand-off to a separate service agent.
