Konica Minolta bizhub C451i: Powerful A3 Colour Printing for Demanding Business Workflows

The Konica Minolta bizhub C451i is a high-performance A3 colour multifunction printer designed for businesses that need professional colour output alongside fast monochrome and colour document production. It combines printing, copying and scanning with advanced connectivity, large paper capacity, flexible finishing options and a modern touchscreen interface.

With speeds of up to 45 pages per minute in A4 for both colour and monochrome, the C451i is designed for demanding office environments where productivity, document quality and workflow flexibility are important. For A3 documents, the rated speed is up to 22 pages per minute in both colour and monochrome.

High-Speed Colour and Monochrome Printing

One of the biggest strengths of the bizhub C451i is that it does not force an office to choose between speed and colour.

The system provides:

Up to 45 ppm in A4 colour
Up to 45 ppm in A4 monochrome
Up to 22 ppm in A3 colour
Up to 22 ppm in A3 monochrome

This makes the C451i suitable for environments where users regularly switch between everyday black-and-white documents and colour-heavy materials such as presentations, proposals, marketing documents and reports.

Fast First-Page Output

The C451i has a listed first-page-out time of approximately 3.8 seconds for monochrome and 5.0 seconds for colour A4 output, with a warm-up time of approximately 12 seconds for monochrome and 13 seconds for colour.

That combination helps reduce waiting time for both short individual print jobs and larger shared-office workloads.

Advanced A3 and Media Support

The bizhub C451i supports a broad range of media, from A6 through SRA3, as well as customized paper sizes and banner media up to 1,200 × 297 mm. Supported media weights extend from 52 to 300 g/m², depending on the input/output path and configuration.

This makes the machine useful for more than ordinary office paperwork.

Businesses can use it for:

  • Presentations
  • Business proposals
  • Reports
  • Posters and notices
  • Brochures
  • Marketing material
  • Training documents
  • A3 charts and diagrams
  • Professional client documentation
  • Banner-format documents

Large Paper Capacity

The C451i is designed for organizations with substantial printing requirements. Standard paper input capacity is listed at 1,250 sheets, while the maximum configurable capacity can reach approximately 7,300 sheets with optional equipment.

The standard manual bypass tray accommodates up to 150 sheets and supports A6-SRA3 media, customized sizes and banner paper.

For busy departments, this flexibility helps reduce interruptions caused by constantly replenishing paper.

Professional Colour Output

The C451i uses Simitri V polymerised toner and laser imaging technology. Its printer resolution is specified at 1,800 equivalent × 600 dpi, with support for 1,200 × 1,200 dpi print resolution depending on the printing configuration.

This makes the C451i well suited to documents where colour accuracy and professional presentation matter, from proposals and presentations to customer-facing documents.

Large 10.1-Inch User Interface

The C451i features a 10.1-inch colour touch panel with a resolution of 1,024 × 600. The interface is designed to provide easier access to printing, copying, scanning and workflow functions from a single control point.

With 8 GB of system memory and a standard 256 GB SSD, the machine is also equipped to support modern document workflows and internal document storage. An optional 1 TB SSD can be configured.

Advanced Scanning

The C451i can be configured with an automatic document feeder supporting up to 300 originals, with A6-A3 document sizes and a dual-scan ADF. Double-feed detection is standard.

This can be especially useful for offices digitizing multi-page documents, contracts, reports and records.

Mobile and Network Printing

Modern offices often work across desktops, laptops and smartphones. The C451i supports Ethernet networking, USB connectivity and optional Wi-Fi. Its supported mobile printing options include Apple AirPrint, Mopria for Android and Konica Minolta Mobile Print for iOS/Android.

This gives employees more flexibility in how they send documents to the printer.

Finishing Options for Professional Documents

One of the C451i's strongest advantages is its range of optional finishing capabilities.

Depending on configuration, businesses can add functions such as:

Sorting, stapling, punching, half-folding, letter-folding, booklet making, post insertion and Z-folding.

This can help transform the C451i from a simple printer into a broader document-production and presentation system.

For example, a company can produce a multi-page presentation, have it automatically sorted and stapled, and prepare finished documents without manually handling every set.

Productivity for Demanding Workflows

Konica Minolta lists a recommended monthly volume of 40,000 pages and a maximum monthly duty cycle of 200,000 pages for the C451i. These figures indicate that the device is designed for significantly more demanding environments than a conventional desktop printer.

As with any printer, actual recommended usage should be determined according to the organization's workload, configuration and operating conditions.

Security and Document Management

The C451i is designed as part of Konica Minolta's modern business MFP range, combining network connectivity, local document storage, user boxes and security-oriented features.

The system supports public and personal user boxes, with personal boxes capable of password or authentication protection. It can store up to 3,000 documents or 10,000 pages across its user-box system, depending on configuration.

This can be helpful for organizations that want to keep frequently used documents available digitally rather than repeatedly recreating print jobs.
