Samsung M3820ND Toner Cartridges

Hi Pauline, this is entirely up to you, as the only difference between the cartridges listed are the capacities. The MLT-D203E will last longer and be better value for money too. We do also offer our own brand versions of these products for a cheaper price. If you would like any further assistance with your order please email [email protected] or call 0345 365 3605 and our customer care team will be more than happy to help. Have a great day!

Hi there, thanks for your question.

To answer your first question about a printer rejecting a compatible cartridge...This happens because there is a chip on every toner and the printer reads the chip for up-to-date software. To prevent the use of compatibles, a printer manufacturer will often automatically update the printer software which means the chip on a compatible no longer matches the printer software and the compatible is rejected.

Unfortunately, manufacturers do this a lot, but there are ways around getting the printer to bypass the error messages if you prefer to buy compatibles. (you can read how to do that here)

We offer a 3-year guarantee on all of our compatibles and 90% of the time they will work perfectly, but if you plan to keep some stocked up, when you come to use them you might have issues.

The top 3 products on the page are compatible toners and print 10,000 pages, 5000 pages and 3000 pages respectively. The last 3 products on the page are original Samsung and again print 10,000 pages, 5,000 pages and 3000 pages respectively.
