    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.

    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.

    MLT-R116 Imaging Unit

    The genuine black Samsung R116 imaging unit is compatible with the Samsung Xpress M2675. Details on how to replace the imaging unit can be found in the user manual for your printer.

    Answered by Sarah Brook (Staff Member) - about 4 years ago
  • Hello, I have this printer and unfortunately since few days the printing is quite light. We replaced the toner but unfortunately no luck. Will that be due to drum? Will replacing drum solve the problem? Thanks

    Printer prints light

    Thank you for your question.

    I am sorry to hear that you have been experiencing a problem.

    If you are experiencing a problem with print quality and replacing the toner cartridge has not resolved the problem, this could also be due to the drum unit.

    I would recommend referring to the manufacturer of the print first of all to see if they can advise any troubleshooting before purchasing a new drum unit.

    Your user manual should also contain troubleshooting advice on problems with print quality.

    I hope this helps.

  • Hello , how do I repair a fuser failure on my Samsung Xpress M2825DW printer? Is there a replacement assembly available that I can buy?

    Samsung MLT-R116 maintenance supply

    Sorry, the item listed here is the original Samsung MLT-R116 imaging drum for the Samsung Xpress M2825DW laser printer. We don't currently stock a fuser for the Xpress M2825DW printer so we'd advise you to contact Samsung directly as this maintenance item might only be available direct from Samsung.

  • Hello, does this printer have a waste toner maintenance box that needs to be replaced?

    Samsung R116 product information

    This is a genuine Samsung MLT-R116 imaging unit which is a different part to a waste toner cartridge and works in any of the printers listed on this page. We would need to know the full make and model of your printer to advise you if it requires a waste toner cartridge and, if so, the correct part number for your machine.

    Answered by Sherena Walker (Staff Member) - about 5 years ago
  • I have a Samsung Xpress M2835DW printer and wanted to know if the MLT-R116 is compatible with this printer. Also, can I install this once the other cartridge has finished? Could you give me this information as soon as possible and tell me what the difference is between an imaging drum and a normal cartridge?

    Samsung MLT-R116 drum replacement

    We can confirm that this genuine Samsung MLT-R116 image drum is compatible with any of the printers listed on this page, including the Samsung Xpress M2835DW. The Xpress M2835DW and other printers in this series use a separate black toner and drum that have different jobs within the machine and are replaced independently of each other. This genuine Samsung MLT-R1116 imaging unit is repsonsible for creating a high resolution image before it's printed out. Unlike the toner cartridge, it doesn't contain any toner particles and is a printer maintenance item that needs to be replaced every 9,000 pages (approximately). The toner cartridges (MLT-D116S or MLT-D116L) are replaced independently of this MLT-R116 drum and are needed to supply the drum with toner particles. Your M2835DW printer only requires one toner and one drum to be installed so you have an option to use a standard capacity or a high capacity toner depending on how often you're likely to print. Please refer to: https://www.cartridgesave.co.uk/toner-cartridges/Samsung/Xpress-SL-M2835DW.html
