[QUOTE="VA1DER, post: 217366, member: 15186"] With respect to page yields, Brother doesn't use the 5% coverage method. They use the[URL='https://support.brother.com/g/s/id/pdf_pub/ink_regular_24711/declared_page_yield_ink_Regular_en_R02.pdf'] ISO 24711 standard[/URL]. It is a pretty resasonable sample of pages that mimic real-world usage cases pretty closely. When they give you page yields, you can usually trust them pretty well. Incidentally, their speed testing is also done in accordance with similar ISO standards with pages that have real-world coverages on them. I personally own the similar MFC-J6945DW printer, which is also an Inkvestment printer, and I love it. It is hands down the best printer I've ever owned, and I am a bit of a printer aficionado. I do a lot of printing, but it tends to be in batches with very long periods in between. I have never had any issues with ink clogging with this printer - I have only had to do a head cleaning once. This is significantly better than any other inkjet printer I have ever had. I can't say exactly how much ink gets run through the printer during its own routine, but my sense is very little. I never see my remaining page counts or ink percentage drop even after long periods of disuse. The signs of ink going bad are frequent clogs. Ink consists of pigments or dyes (pigment for Brother) in a liquid solvent. As inks sit the solvent tends to evaporate slowly, which makes the ink viscous and clogs the heads frequently. I've only had my printer about a year and a half now, so not the three years you are contemplating. But I have replaced the colour cartridges, so the black is still original. There is no sign my printer is clogging - I think the seals in Brothers are pretty good. I [URL='https://productrevue.ca/index.php/brother-mfc-j6945dw/']wrote a detailed review[/URL] of my printer. Some of it doesn't apply to the 995 you are considering, but it does speak to brother's philosophy in general. And if you can afford the space and difference in price, the 6945 is a great buy too.
