This printer is not designed to use continuous ink systems.

the printer is displaying "This printer is not designed to use continuous ink systems. To resume printing, remove continuous ink system and install original HP (or compatible) cartridges."

at first it was the magenta, i replaced it, problem disapeared, the it happened with cyan and the yellow, replaced all cartridges,

now it is with black.... what the hell is wrong with the printer?? it seems that the printer is forcing me to change cartridges (original ones), i'm filling the with ink, they worked just fine!

Why the hell does HP puts restrictions on cartridges??? i want to re-use those cartridges!

Please find me a solution to my (or even to all) problem.

Thank you.

Hello Betty

I\ve already tried the above documents you sent.

unfortunately replacing the cartriges worked instantly.

I want to use the same cartrige - i don't want to replace the cartridge every time.

I know you want to sell HP cartridges, but i want to use any cartridge i want and want to use it long term.

I realy don't mide the security chip as long as it doesn't restrict using continuous  ink cartrige system.

Please remove this restriction as it restricts my printing and scanning abilities until replacing the cartridges.

I love HP and wants to continue using it (also my computer), I bought this product and doesn't like to be restricted in any hardware or forcing me to replace a good working cartridge.

Please make an update soon as i don't want to encounter another issue with that security chip or continuous ink system problem.

FYI: this has caused me a lot of inconvinience since the corona virus and i was unable to buy new cartridge for duration of one month which i couldn't print anything for my kid who learns at home

Thank you.
