Yesterday I have now been allowed to carry the second cartridge from the T1285 strength pack in the dustbin because my printer says these cartridges not compatible. Toll !!! The 13er series, which I have always bought the printer detects properly. That can not be true?!? That the device does not accept cartridges that are intended for it. Since I wanted the level of the individual cartridges, because some more colors are used, and have leveled .... thrown the money in the bin in the truest sense of the words. As for open cartridges to be claimed? Well ....
