The cartridges come as shown without chip. This one must first be separated from the empty original cartridges (one reference is made to an Internet link in the supplement of the savings packs where the exact As is explained) friemeln and with the accompanying adapters in the related subjects of the printer carriage. Now set the desired color cartridges and off you go.
For big but:
The color quality is of course not quite compare with the original cartridges, but this is not necessarily a bad thing because of the almost ridiculously low price. The color containers are filled to the brim and you can happily hindrucken right, everything is working as usual. On the level indicator you have to give of course, since it passes over the chip to the cartridge and you have to work with already used chips here. Whether there is some extra color to the containers is thus determine with your own eye (for those things are also transparent).
What is more disturbing so many is the fact that, of course, HP has thought and a printer now also has its own small computer, the things that are noticed the manufacturer is not so dear. In practice this means that after insertion of the savings packs and turn on the printer, a message will appear on the display, the first one a small Oha! elicits. The printer has "noticed" that no one has used original cartridges and confronted one with the warning that this will also affect any warranty claims.
That is, the printer within the warranty period should break times can read exactly what you've done with the device's repair shop, how much one has printed, whether it was with the original cartridges, etc. and will refuse may repair perform under warranty.
What bothers me is not that why I will probably continue to rely on this product.
