Though modern printers are cheap as chips, the ink costs are usually astronomical. My new printer is no exception, though one reason I did purchase it was because it had separate ink cartridges rather than the usual one black and one colour that lower end printers have.
The Canon MG7752 printer comes with, what are called, setup cartridges, I have no idea how different these are to the regular ones, but having got the printer at the end of March they started to run out this month, July.
As well as regular document printing, it is also used quite a lot to print photographs, the second 6×4 paper tray makes that simple and easy to do from either the Mac or from the iPhone.
The printer has two black cartridges, Cyan, Magenta, Yellow and also uses a specialised Grey cartridge too.
The printer can take regular cartridges, which I am assuming contain more ink that the setup ones. There are also XL high yield cartridges which according to the marketing hype deliver twice the pages of a regular cartridge.
The first setup cartridge to run out was the double sized black cartridge which is used for black and white output. This lasted from the end of March to the beginning of July, just over three months. The colours started to run out in the third week of July starting with the Cyan, followed by the Magenta, then the Yellow and then the Grey. The other black cartridge still has ink in.
I bought XL versions of the colour cartridges so it will be interesting to see how long they last. Challenging to measure effectively as the printing usage patterns in the house vary quite some bit. However by posting this post I hope to have some kind of record of how long the cartridges last.
