Ink cartridges Canon printer (SY16 Newtown)

I have three of the small '6' black unopened. Two of them are off brand and one is Canon. I had also just put new black cartridges in when the printer gave up the unequal struggle for life and so there are two opened black ones: one the large 3e and one of the '6'. See the photos for the printers that the cartridges fit.
