Ink Cartridges

HP Recommended

Why can't I use aftermarket ink in my 7740 printer. The fact that you have rigged these machines to accept nothing but HP ink is about the most low down thing a company has ever done. I will never buy anything that has the name HP on it. (except of course your over priced ink cartridges)

@43adam, Welcome to the HP Support Community!

 

Certain HP printers use cartridges that have security chips or electronic circuitry. Cartridges using a non-HP chip or modified or non-HP circuitry* may not work, and those that work today may not work in the future.

 

This is a Dynamic security enabled printer. The Firmware Update may prevent supplies with non-HP chips or circuitry from working.

Note: For printers manufactured prior to December 1, 2016 dynamic security will not be enabled by the firmware. Please note that HP cannot guarantee the quality or reliability of non-HP cartridges.

You may refer to this document -  HP Printers - Dynamic Security Enabled Printers

 

Hope this helps! Keep me posted.
