Canon i-SENSYS MF8340Cdn — Review: Features, Specs

By -

1. Overview & Positioning

The Canon i-SENSYS MF8340Cdn (also known in some regions as the Canon imageCLASS MF8340Cdn) is a color laser multifunction printer (MFP) designed for small to medium-sized offices. It offers printing, scanning, copying, and automatic duplex (2-sided) printing, and is built to deliver reliable color output without the cost and complexity of heavy production machines.

With a rated monthly duty cycle of up to 40,000 pages, it is well-suited for consistent business use but is not a high-end production printer. Its balanced design — decent speed, duplex, network connectivity, and color — makes it a practical “workgroup MFP.”

2. Key Features & Specifications

Here are the most important specs and features of the MF8340Cdn, based on Canon’s design and multiple sources:

Print / Copy

  • Print Technology: Color laser beam printing.

  • Print Speed: Up to 20 ppm in both mono and color.

  • Resolution: Native 600 × 600 dpi; enhanced mode up to 2,400 × 600 dpi for better print quality.

  • First-Page-Out Time: ~14.5 seconds (mono and color).

  • Duplex Printing: Automatic two-sided printing supported.

  • Print Language: UFR II-LT (host-based), which is common in Canon’s business printers.

  • Copying: Up to 20 cpm for both black and color, with 600 × 600 dpi resolution.

  • Copy Features: Zoom from 25%–400%, Frame Erase, Collate, 2-on-1, 4-on-1, ID card copy.

  • Scanner Type: Flatbed + 50-sheet DADF (Document Feeder).

  • Optical Resolution: 600 × 600 dpi.

  • Enhanced / Interpolated: Up to 9,600 × 9,600 dpi according to product listing.

  • Color Depth: 24-bit input for color scanning.

  • Scan Destinations: Supports scan to folder (network), USB, e-mail.

Connectivity

  • Interfaces: USB 2.0 Hi-Speed, Ethernet (10/100).

  • USB Host: Yes, allows printing/scanning from USB flash drives.

  • Network: Wired Ethernet but no Wi-Fi on this model. According to specs, Wi-Fi is not listed.

Memory & Duty Cycle

  • Memory: 256 MB shared memory (for print/scan/copy).

  • Monthly Duty Cycle: Rated for up to 40,000 pages/month.

Paper Handling

  • Input Capacity: According to some sources, up to 300 sheets standard input.

  • Multipurpose / Bypass Tray: 50-sheet multipurpose tray.

  • Output Capacity: 125 sheets.

  • Media Sizes: Supports A4, A5, B5, Legal, Letter, Executive, Statement, envelopes (various), and custom sizes from 76.2 mm to 216 mm wide. 

  • Media Weight Support: 50–220 g/m² in MPT, and similar range for main tray.

Power & Physical

  • Power Consumption:

    • Maximum: ~1,200 W

    • Standby: ~23 W

    • Sleep / low-power mode: ~1.8 W

  • Dimensions: ~430 mm (W) × 484 mm (D) × 479 mm (H).

  • Weight: ~31 kg.

Consumables (Toner)

  • Uses Canon 718 / 716 (or similar) cartridges depending on regional version. For example: 718 series CMY = ~2,900 pages, black ~3,400 pages per some supplier specs.

  • Drum / imaging unit is separate from toner, which means replenishing toner doesn’t necessarily mean replacing the drum immediately.

Display & Interface

  • Control Panel: 5-line backlit LCD + hardware buttons for navigation.

  • Key Functions: Shortcut keys likely include scan-to-folder, secure print, economic copy, etc. (based on similar Canon MF devices).

3. Performance & Real-World Use

Printing & Productivity

  • At 20 ppm for both color and mono, the MF8340Cdn is not blazing fast but provides consistent, usable performance for typical business document jobs.

  • The first-page-out time (~14.5 seconds) is decent for a color laser of this class — suitable for standard office workflows.

  • Automatic duplexing (double-sided) helps reduce paper costs and is helpful for business reports, proposals, and internal documents.

Scanning / Copying Efficiency

  • The 50-sheet DADF streamlines scanning and copying of multi-page documents, though since it’s not a “single-pass duplex ADF,” scanning two-sided originals may require manual flipping depending on the model’s architecture.

  • Optical scan resolution (600 × 600 dpi) is sufficient for document archiving, OCR, and color graphics — though not ultra-high-resolution photo scanning.

  • With network scan destinations (folder, email), the MF8340Cdn can integrate into business digitization workflows.

Reliability & Maintenance

  • Canon’s color laser design is mature and generally reliable for business use, especially in moderate-to-high duty environments.

  • The 256 MB memory is enough for standard document jobs, but very large or graphics-heavy print jobs may stretch it.

  • Toner usage: Color pages will cost more, particularly if coverage is heavy; drum replacement cycles need to be planned for in cost-of-ownership.

Energy & Efficiency

  • The power draw is high when active (~1,200 W), so energy management (sleep, auto-off) is critical for minimizing electricity cost in low-use scenarios.

  • The device’s standby (23 W) and sleep (1.8 W) power states are relatively efficient for a laser MFP.

4. Business Use Cases & Suitability

Here are scenarios where the MF8340Cdn is a very good fit — and where it might be less optimal.

Ideal Business Use Cases

  1. Small to Medium Workgroups

    • Teams of 5–15 users printing and scanning business documents, presentations, and occasional color marketing materials.

    • Shared office spaces where network connectivity (Ethernet) is available and where color is needed but high-volume production is not the core.

  2. Marketing / Design Support

    • For producing internal color collateral, mock-ups, sales flyers, or simple brochures on demand without outsourcing to external print shops.

  3. Document Archiving & Digitization

    • With scan-to-folder or scan-to-email, the MF8340Cdn can serve as a document digitization tool for contracts, reports, and paper-based workflows.

  4. Office Reports & Duplex Documents

    • Automatic duplex printing makes it effective for report printing, double-sided handouts, proposals, and internal documents that benefit from 2-sided output.

Less Suitable Scenarios

  • High-Volume Production Print Rooms: For offices that print thousands of pages of color per day, a more specialized production color laser may be more cost-effective.

  • Mobile-Only or Wireless-First Workplaces: Because this model lacks Wi-Fi, printing from mobile devices requires tethering or a network print server.

  • Photo or Graphic Studio: For high-fidelity photo printing, the 600 dpi color resolution and UFR II-LT architecture aren’t designed for professional photo output.

  • Heavy Scanning Load: For very large scanning or copying tasks (especially double-sided), a more robust scanner or MFP with higher-speed ADF may suit better.

5. Strengths & Weaknesses — Summary

Strengths:

  • True 4-in-1: print, scan, copy, automatic duplex.

  • Color laser output at a moderate business speed (20 ppm) — good balance of color and document productivity.

  • Networked via Ethernet — well-suited for shared workgroups.

  • Duplex printing saves on paper and supports professional document output.

  • Robust duty cycle (40,000 pages/month) makes it reliable for consistent business workloads.

  • Toner-based: more stable toner storage than ink — ideal where printing intervals vary.

Weaknesses:

  • No Wi-Fi, limits mobility / wireless printing.

  • Relatively high power consumption when active.

  • Toner cost for color will be significant for frequent color printing.

  • Scanner resolution is moderate — not for ultra-high-res scanning.

  • 256 MB memory may limit very large or complex jobs.

6. Deployment & Management Tips

To make the most of the MF8340Cdn in a business environment:

  1. Use Duplex as Default
    Configure print drivers to default to two-sided printing. This reduces paper use and aligns with its strength.

  2. Manage Toner Inventory
    Keep extra color and black toner cartridges on hand, especially if color printing is regular.

  3. Implement Power Policies
    Use sleep mode and auto-off during non-working hours to reduce energy usage.

  4. Leverage Network Scanning
    Set up “scan to folder” or “scan to email” jobs for common workflows, making document digitization easier.

  5. User Training
    Train users on how to use the DADF for scanning and copying, and how to use the LCD interface for shortcuts.

  6. Performance Monitoring
    Monitor usage, toner depletion, and error logs via Canon’s remote user interface or network management tools.

7. Final Verdict

The Canon i-SENSYS MF8340Cdn is a well-balanced, reliable color laser MFP for businesses that need more than just black-and-white printing, but don’t require a high-end production printer. It’s particularly well-suited for offices, design-support teams, or departments that need to digitize documents, print color materials, and produce duplexed documents.

  • ✅ Recommended if:

    • You want to share a color MFP on a network, and color print volume is moderate.

    • You use scanning and copying in your daily workflows and need to streamline them.

    • You want automatic duplex printing to reduce paper usage.

  • ⚠ Consider alternatives if:

    • You require wireless printing from mobile devices.

    • You do very high-volume color printing and want lower cost per color page.

    • You need very high-resolution scanning for graphics or archival scanning.
