    • 3-year warranty
      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.

  • I've been told our franking machine is Pitney Bowes model number K721M. Is that the same as the K721 quoted on your website? I need to make sure the cartridges are the same.

    Pitney Bowes K721 printer model numbers

    Provided that you have a UK version of a Pitney Bowes K721 series franking machine, we guarantee that any of the ink cartridges listed on this page will work in the printer. This currently includes the compatible 797-0 red ink cartridge and the compatible 797-0SB blue ink cartridge.

  • My cartridge for the K721 franking machine looks a bit different on top from the one you're showing. Will this cause a problem when fitting?

    Compatible K721 cartridge looks different

    If you're using a genuine Pitney Bowes K721 ink cartridge then it will look slightly different to the cartridge we're supplying which is made by another retailer as a cheaper alternative. Pitney Bowes cartridges have a patented design which can't be copied. However, this should not cause a problem for you because our compatible K721 ink cartridges are also Royal Mail approved and are guaranteed to work in your franking machine as well. We offer a money back guarantee on these compatible Pitney Bowes K721 ink cartridges so if they don't fit your printer and work reliably you can send them back for a refund or replacement.

    Answered by Tamara Sawyer (Staff Member) - about 6 years ago

  • The last cartridge I bought for my Pitney Bowes Mailstation K721 had red ink. You're now giving me the option of blue. Is this okay for Royal Mail use?

    Blue ink for Mailstation K721

    Yes, Royal Mail are eventually changing from red to blue ink as they found that their machines read blue ink more easily.

    If you were to switch from red to blue now, we would advise you to have your machine professionally cleaned to clear any red ink from inside the machine.

    You can check with Pitney Bowes to see if this will be necessary for your machine, as not all of them will require a clean to be done.

    Answered by Tamara Sawyer (Staff Member) - about 7 years ago

  • Hi, I've had the red Pitney Bowes K721 ink from you in the past but see now that you sell them in blue. Is this compatible with Royal Mail? Paul Richards.

    Pitney Bowes K721 blue cartridges

    Yes, eventually all franking machine cartridges will be changing to blue in line with Royal Mail requirements. They had tested the colours and the scanning machines can read the blue ink much easier than the red.

    If you'll be changing to blue from red, we would advise that your machine may need to be professionally cleaned but Pitney Bowes can clarify this if you contact them.

Pitney Bowes K721 Printer Review

Expert review of the Pitney Bowes K721 printer

Our Verdict:

One of the most reliable digital franking devices in the market, the Pitney Bowes K721 is part of the ever-reliable Mailstation series, offering easy to use and maintain franking machines for offices and businesses looking for an efficient way to lower their postage expenses. The Pitney Bowes K721 allows 20% savings on mail and post expenses, saving users a good deal of money from regular stamp purchases and trips to the post office. What's more, they can personalise the mail they send through envelope messaging.

Design

The Pitney Bowes K721 franking printer adopts the same design as its brothers in the series, featuring a classic matte blue and grey finish. The Pitney Bowes K721 has a built-in weighing scale mounted on the right side of the unit, while the control panel sits right below the LCD display. Envelopes, labels, and parcel packaging can be inserted into the proper slot, when the machine is ready to print. The Pitney K721 franking machine is sleek and compact at 351x264x231 mm, although some may find it quite bulky for a machine that only does one simple function.

Advantages

The Pitney Bowes K721 mail franking unit allows offices to drive down their postage expenses and efficiently track the outflow of money used for mailing letters and parcels to consumers. The Pitney Bowes K-721 printer also allows businesses to be constantly in the know of the latest postage rates.

Disadvantages

A very task-specific machine, the Pitney Bowes Mailstation K721 franking machine is not for everyone; however, it is a must-have device for those who send bulk mail every day.
