I have NEVER had a BAD Compatible Cannon ink cartridge from Stinkyink . To the best of my knowledge they perform just like the Cannon equivalent on my very old iP4600 printer, that is to say there is no mess, no fuss the cartridge replacement as it just drops straight in. Also my iP4600 was upgraded a year ago to do double sided printing and the ink drying time between between pages (set by the printer) gives the same perfect print quality. Highlly recommended.


I have a CYAN cartridge C-526 from my recent order number
ST852716784 unfortunately when I inserted this items into my
Canon 6150 printer it does not register (therefore it has not been used at all). Can I return this item to you for replacement or should I wait for my next order.

Sorry the cyan isn't being recognised.

With the cartridge not being recognised sometimes the contact chip on the cartridge needs a clean.

If you give the contact chip a rub with a pencil eraser or a dry lint-free cloth and then switch the printer off at the mains for 2-3 minutes and reinstall the cartridge this will clear any errors from the printer's memory.

If you are still having issues please let us know and we can arrange a replacement for you.

No problem with the delivery.
BUT I've just put in new Magenta and the big Black one, but the printer is still saying they are not OK. Both the relents I put in were probably nearly a year old - do they go "off"?
