      3-year warranty on our own-brand cartridges
      We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
      Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
      We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
      Our own-brand cartridges are incredibly reliable for three reasons:
      1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
      2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
      3. We constantly monitor customer feedback, and quickly resolve any issues.
    • Printer protection guarantee
      Our cartridges won't damage your printer—guaranteed
      Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
      To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
      Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, the manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong, and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.

      In summary, there’s zero risk in using our own-brand cartridges.

OKI MB770 Printer Review

Expert review of the OKI MB770 printer

Our Verdict:

Built for medium-size workgroups, the Oki MB770 printer, scanner, copier, and fax machine is designed to improve your bottom line, enhance workflow and control outputs in the work environment. The device even boasts energy-saving and environment-friendly features, making it an appropriate choice for green companies. The Oki MB770 is a compact MFP with a small footprint, ideal even for offices with small workspaces. However, this device can only do monochrome printing and is not equipped for colour production.

Design

The Oki MB770 is compact enough for desktop operation, measuring only about 20.6x23.8x26.6 inches. It comes with many standard features like an automatic duplexer, a 2GB internal memory, Ethernet interface and high-speed USB port, a 630-sheet paper tray, and a highly intuitive control panel, from which you can access menus and functions seamlessly.

Advantages

The Oki MB770 prints and copies at an average speed of up to 55 pages per minute. It can turn out pages in as little as 5 seconds after booting, and scan options are very flexible, allowing you to save files in multiple locations, including your network folder, PC, a USB stick, or a bunch of email addresses. The Oki MB770 even features a colour touch-screen display and a convenient alphanumeric keypad with other function buttons for easy controls.

Disadvantages

The Oki MB770 all-in-one printer is a suitable addition to medium size offices. However, it is not the best choice for those in need of a device that does high-resolution colour printing, as the printer's engine can only accommodate monochrome documents.
