      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.

      compatible cartridge is not the real thing but the price is accordingly to the quality.
    2. 100%

      By Linda B on

      Good quality as all the items i have purchased from cartridgesave previously, sadly my old Oki printer wasn't happy to accept anything other than OKI original and wouldn't print, i experienced good help and customer services from cartridgesave staff who gave me reset info, but sadly no joy even when they sent other replacement items. I contacted OKI and they confirmed that my printer will not accept compatible items and there is no way of putting in a code to allow the printer to accept any, i suggested that i will not be buying any Oki printers in future.
    3. 100%

      By Johnb on

      These work perfectly and do exactly what they are supposed to do at a fraction of the price of the branded ones. The instructions that came with them were excellent and even told me how to get rid of banding caused by a dirty led array.

      Great!
    4. 100%

      By A.Gibson on

      First class product at half the price of a new Oki toner.
    5. 100%

      By George on

      I find that my OKI B410d laser printer can be so cheap to run with the compatible cartridges. Price is very competitive.
      Reproduction (including photos) is first-class and certainly give value for money.
      Delivery was prompt and well packaged.
      I shall be back for more.

      By Andy Jack on

      I'd just bought an Oki laser printer and am always suspicious about the amount of toner or ink supplied with new printers. I looked online and thought I'd found a high capacity cartridge. I ordered from CartridgeSave and it arrived quickly. I then realised that it wasn't the right one, rang CartridgeSave and they immediately offered a refund and replacement which duly arrived a day or so later.

      My fault entirely confusing 410 and 401 in the model number. Thanks to Cartridge Save for sorting me out,

    1. 100%

      By Linda B on

      Good quality as all the items i have purchased from cartridgesave previously, sadly my old Oki printer wasn't happy to accept anything other than OKI original and wouldn't print, i experienced good help and customer services from cartridgesave staff who gave me reset info, but sadly no joy even when they sent other replacement items. I contacted OKI and they confirmed that my printer will not accept compatible items and there is no way of putting in a code to allow the printer to accept any, i suggested that i will not be buying any Oki printers in future.

      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 B440dn Printer Review

Expert review of the OKI B440dn printer

Our Verdict:

An office printer needs to offer a few key features and thankfully, there is much to be said for the Oki B440dn. Of course, there are plenty of leading brands in this industry and you might not be entirely aware of the finer aspects of the Oki brand, but if you are seeking out a very reliable office printer, you cannot go far wrong with an Oki B440dn. There are plenty of places to start, so why not begin with the design aspect of the Oki B440dn?

Design

If you are looking for a printer which promises a great deal and manages to deliver, then the Oki B440dn is certainly worthy of investigation. However, we are yet to come across an office printer which is, in truth, overly attractive. Thankfully, this doesn't really matter any and as far as a technical design aspect is concerned, the Oki B440dn is very well put together and an easy to operate interface is included on this fine printers casing.

Advantages

The Oki B440dn offers plenty of perks, including speed. In many ways, speed and reliability are exactly what you require from an office printer and the Oki B440dn boasts both these aspects. What's more, the Oki B440dn is something of a workhorse, ensuring that even the busiest of offices could benefit from the addition of an Oki B440dn.

Disadvantages

We always struggle in this department as some printers really don't have a great deal of negative aspects. The Oki B440dn is one of these printers. As such, even if you are seeking a basic office printer, you could do far worse than consider forking out the cash for an Oki B440dn as it really does do everything you might wish an office printer to provide.
