Although the cartridge came super fast (Prime) here, but the surprise was great: One sees immediately that the housing is manipulated, ie lacking in comparison to the original Noses and other Kerben.Setzt to the cartridge then it is much too loose in it and the printer, me an MX340 does not recognize them. Although he printed with the cartridge but he remains "in faith" that the black cartridge is almost empty. Therefore, it is the green warning light remains lit and incoming faxes are only read into memory, do not print, you have to then enforce. (I know I know, who has already faxing nowadays but I have customers who still send me faxes if they order something ...) I've then taken today for 17 euros an original that for here are 11 euros a waste of money. But you always learn again what it.
