What Makes the OKI C911dn Different

This printer is not a typical office colour laser. Below are the features that set it apart from the A4 colour devices most businesses currently rely on - each one explained alongside the relevant product imagery.

True A3 Colour at 28ppm Most office colour printers cap out at A4. The C911dn prints a full A3 sheet at 28ppm in colour, which means you can produce double-sided A4 brochures laid out on a single A3 spread, A3 posters, A3 plans and oversized presentation handouts in-house. For anyone who has run brochure work through an A4-only device and then trimmed and stitched the pages together, the time saving is immediate. Output is true 1200 x 1200 dpi for sharp text and accurate colour.

Heavy Stock up to 360gsm via the Multi-Purpose Tray The 300-sheet multi-purpose tray accepts media up to 360gsm - heavier than most production card stocks. That opens up business cards, postcards, presentation folders, menu cards and durable signage without needing to outsource. Automatic duplex still operates up to 320gsm, so double-sided card work is in scope too. Compatible media includes gloss paper, film, transfer paper, waterproof paper, labels and standard plain stock.

Banner Printing up to 1.3 Metres Long The C911dn supports banner stock up to 1.3 metres in length, which is genuinely unusual at this price point. Window signage, seasonal POS, exhibition banners and long-format prospectus pages all run through the multi-purpose tray. For retail, hospitality and real estate teams, this single capability often justifies the printer on its own - there is no waiting for an external printer, and turnaround on new signage drops from days to minutes.

Scalable Paper Capacity up to 2,950 Sheets Standard configuration ships with 830 sheets across the main tray and multi-purpose tray. Optional additional trays scale capacity up to 2,950 sheets - useful for shared departmental use or for keeping multiple stocks loaded at once (plain in tray 1, letterhead in tray 2, gloss in tray 3, for example). With the 300,000 page monthly duty cycle backing it up, this is a printer built to take sustained punishment without complaint.

Long-Life Drums, 24K Toners, 3-Year Onsite Warranty The C911 uses separate image drum units rated to around 40,000 pages each. You only replace the part that has actually worn out - not the whole cartridge. Genuine OKI 24K toners deliver 24,000 pages per colour at 5% coverage, which keeps the cost per page competitive with managed print contracts. Every C911dn is backed by a 3-Year Onsite Warranty when registered with OKI within 30 days of purchase, plus a 5-year warranty on the LED printheads themselves.

Full Technical Specifications

Who Is the OKI C911dn Best Suited For?

The C911dn is built for organisations that need genuine A3 colour, heavy media handling and high monthly volumes - but don't want to step up to a full production press. Typical buyers include:

Compatible Toner Cartridges - OKI C911 / C931 / C941 Series

The OKI C911dn uses the OKI 24K toner series - the same cartridges fit the C931 and C941 models. All four colours are available from CartridgesDirect with fast Australia-wide delivery.

Genuine OKI 24K Toner Cartridges

Each cartridge yields up to 24,000 pages at 5% coverage (ISO/IEC 19798). A full CMYK set fitted to the printer delivers approximately 96,000 pages of colour output before the next replacement is needed.

Image Drum Units

Image drums are sold separately from toner and rated to around 40,000 pages each. You only replace the drum when it reaches the end of its service life - not every time you change toner.

Check Before Ordering

Why Choose the OKI C911dn?

The C911dn earns its place in busy offices and print rooms by doing three things genuinely well: it prints A3 colour at production speeds, it handles media that would jam a standard office laser, and it keeps the cost per page low through 24,000 page toners and separately serviceable image drums. For organisations that have outgrown their A4 colour printer but don't have the budget - or the volume - to justify a full production press, it is one of the best-value options on the Australian market.

Running costs stay predictable thanks to the 24K toner yields and the 3-year onsite warranty. Genuine OKI consumables are widely available across Australia, and CartridgesDirect stocks the complete C911 / C931 / C941 range with same-day dispatch on in-stock orders.
