I bought the cartridge for my HP Officejet 6500A, the so, already has the refill stores, I always go to see the new chips represent the original cartridges that should leave no Refill (my refillte Black Cartridge works but anyway). In order to implement the chip onto the adapter, you have to go with the cutter very careful to work - a blip with scratches above the chip, and that was it. Has worked with me but, except for black. In the large cartridge is not about, because the chip does not fit on the adapter. In the little I have to still ausprobieren.Jetzt I have only once a refillte it. After the procedure the Umchippen is definitely a thorough printhead cleaning overdue, otherwise nothing works. After that the printouts are but completely ok (I Prints generally no pictures, and if so, with no claim aufHöchstqualität). Except for a few very small blobs (I use a paper backing) cartridges have no color set apart. I buy me give it back, because the original cartridges are simply extortionate.
