weCare offers solution for blockade by latest HP update

Did you install an alternative for the HP950/951, HP934/935 or HP970/971 and does your HP Officejet printer suddenly tells you that the cartridges are damaged? Don’t panic, your cartridges are working fine. It’s an annoying situation but fortunately it’s fairly easy to solve.

This is caused by HP’s "Dynamic Security Feature" with which they remotely control their printers. This way HP checks if the related printer contains original cartridges with HP chip. If this is not the case and you have installed alternative cartridges, the printer will report the cartridge is "damaged". 

However your cartridges are not damaged at all and they still are working perfectly! HP just wants to force the consumer to use the much more expensive original HP cartridges.

Are you the victim of HP’s Dynamic Security Feature? Then we advice you to download the firmware which connects with the operating system of your printer: Windows (7, 8, 8.1 & 10) & MacOS (10.9, 10.10, 10.11). When the firmware is installed the printer will again recognize your cartridges.
