      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
      “In the unlikely event that Cartridge Save own brand cartridges cause damage to your printer—regardless of how old your printer is—we will repair or replace your printer for free.”
      And they won’t invalidate your printer manufacturer’s warranty...
      If your printer is less than one year old, your manufacturer’s warranty won’t be affected by using our cartridges (this is the law). However, in the unlikely event that our own brand products are to blame, we will take over the manufacturer’s warranty offering phone support and, if needed, repair or replace your printer.

      This means there is absolutely no risk in giving Cartridge Save own brand cartridges a try.

OKI MB770dfn Printer Review

Expert review of the OKI MB770dfn printer

Our Verdict:

The heavy-duty Oki MB770dfn A4 mono multifunction printer is quite cheap for its kind. This workhorse features a large touchscreen display for ease of use and is integrated with a large hard drive. The well-connected Oki MB770dfn black and white MFP is ideal for workgroups of 30 or more. It has excellent paper handling capacity that is scalable and even comes with an internal finisher.

Design

The Oki MB770dfn mono laser printer comes with a flatbed scanner on top along with a 100-sheet RADF. Its control panel features a 9-inch colour touchscreen display, function buttons and a numeric keypad. For paper handling, the Oki MB770dfn laser MFP can carry over 600 sheets but with optional trays it can be increased to 3,160 sheets. This model is integrated with 2GB of system memory and a 160GB hard disk drive. The Oki MB-770dfn printer measures 811 x 522 x 564mm and weighs 60kg.

Advantages

The reliable Oki MB-770dfn mono multifunction laser printer with fax can handle 200,000 pages per month. This robust unit has quick print and copy speeds of 52ppm with the first page out in less than 10 seconds. Scanning speed is also quite quick and can offer a maximum resolution of 600 x 600dpi. For continuous and unattended use, the Oki MB770dfn features a reversing automatic document feeder and a duplexer. For connectivity, workgroups can connect via Ethernet. To ensure security, the Oki MB770dfn all-in-one laser printer has functions such as disable USB host, secure print, storage device encryption, and more. Toner replacement costs for the MB770dfn printer are fairly affordable, especially when users install the more productive Oki 45439002 high capacity black toner.

Disadvantages

Although the MB770dfn laser multifunction printer has standard Ethernet, it would be better if Wi-Fi was also built-in and not optional.
