FAQ

1. What makes the OKI C651 the best printer for small office spaces?

The OKI C651 features proprietary Space Saving Technology, making it the world’s smallest high-performance A4 color printer. Its compact footprint (395mm x 430mm x 290mm) and full front-access design mean you only need 2cm of clearance on the sides to operate and maintain the device. This makes it ideal for cramped retail kiosks, busy warehouses, and tight back-office desks where space is at a premium.

2. How fast is the OKI C651, and does it support high-volume printing?

Despite its small size, the OKI C651 delivers workgroup-level performance with print speeds of up to 35 pages per minute (ppm) for both color and mono. It boasts a rapid first-page-out time of just 6.5 seconds. With a robust 48% metal construction and a maximum duty cycle of 100,000 pages per month, it is built to handle heavy-duty professional workloads without the frequent downtime associated with smaller plastic printers.

3. What types of media and paper weights can the OKI C651 handle?

The OKI C651 offers unrivaled media versatility for its class. It supports paper weights from 60gsm to 256gsm and can print on a variety of sizes ranging from small B8 labels to banners up to 1.32 meters long. This flexibility makes it a favorite for specialized industries, including:

  • Personalisation: Transferpapers & printable stickers.
  • Horticulture: Waterproof and UV-resistant plant tags.
  • Retail: High-quality signage and promotional banners.
  • Automotive: Printing durable car number plates.
  • Logistics: Heavy-duty labels and warehouse documentation.

4. Is the OKI C651 cost-effective for businesses?

Yes, the OKI C651 is designed for an unrivaled Return on Investment (ROI). Unlike many desktop printers, it uses a separate toner and drum system, ensuring you only replace what you use. High-capacity toners (up to 7,000 pages for Black and 6,000 for CMY) and long-life 50,000-page drums help maintain a very low cost-per-page, making it significantly more economical for high-volume color printing than standard consumer-grade models.

5. Does the OKI C651 support mobile printing and wireless connectivity?

The OKI C651 is fully equipped for the modern digital workplace. It features standard Gigabit Ethernet and USB 2.0 connectivity, with an optional Wireless LAN module that supports the latest WPA3 security protocols. It is compatible with Apple AirPrint and Google Cloud Print 2.0, allowing team members to print directly from smartphones and tablets without needing complex driver installations.
