Despite the promised potential Einstzes in a IX6850 the cartridges are not included in this printer, the Canon Pixma IX6850. You get no electrical contact. The yellow go not, the red sporadically. The other colors I Nocht not need to replace. I'll have to look around for a replacement, from another seller. If you press the, inserted in the printer cartridge, contact is made and the LED of the affected cartridge will light, letting them out, breaks the connection to the printer again. The housing of the cartridges are manufactured differently and therefore the retaining lugs of plastic. So that's always a gamble whether the cartridges go. For the first order I had problems that went far all did not try. In the second delivery of other cartridges are apparently there that work so far. Apparently arbitrarily assembled upon delivery, as some models do not work at the IX 6850.
