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 our own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this as problems are almost unheard of.
Your printer warranty is safe
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, 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.

Quick service as always from Cartridge Save. Product arrived well packaged. Changed out Ink's with no issue. Always use cartridge save for my Ink's, good quality, competitive price.

My Brother DCP-J1140DW will sometimes reject a new compatible cartridge but most of the time the Cartridge Save compatibles plug straight in and print - and when you're in desperate need of a replacement, you can rely on Cartridge Save's next day delivery guarantee. After years of reliable service I wouldn't use any other supplier.

All well in the end, but I could not get the ink cartridge in the printer to start with until I discovered a tiny piece of invisible cellophane paper over the ink tube. This should be coloured to be more visible, but at least I will know for the future what the problem is.

I ordered my cartridges after the branch is closed and they were delivered the following day. Excellent service excellent quality of product for my brother printer highly recommend.
