Hi,

can anyone tell me the key sequence how to disable the chip control of the ink cartridges of a HP 9000 printer.

Would be great.

Thanks

Hello
You should have original cartridge chips in yout system (expired or low)
The sequence is (for each color, when you are asked to replace the cartridge)
[Cancel]+[Down] (it propts you...)
[Enter] (prompts you again, and again...)
until you get two options: "Non-HP" and "Replace"
You choose "Non-HP" ([up key]) and hold [Shift]+[Enter] to accept.
