Dynamic Security preventing utilisation of OfficeJet Pro 8500A -A910 with non original ink cartridge

[Palazz]

Officejet Pro 8500A - A910. After installing latest update of firmware from 2016 suddenly one after the other the ink cartridges (non original) stopped working with the message "Ink cartridges seem to be missing or damaged" (translated from German).

I could recover for a while with a factory reset but after printing again a certain number of pages suddenly all 4 cartridges had the problem. Of course I cleaned the contacts, bought new Ink cartridges (from a different vendor), tried again factory reset (also a full factory reset) but the problem does not go away and I cannot print a single page anymore.

Please provide URGENTLY a new firmware release for Officejet Pro 8500A - A910 which excludes Dynamic Security as was done for all the other printers which were already fixed. Alternatively send me a procedure how to downgrade the firmware (I was not able to do that on my own). I'm very close to throw the printer out of the window and NEVER again buy an HP product but I would like to give you a last chance. Thank you

Cleaning the contacts didn't work. I'm fully convinced that it is something in the SW as the problem could initially be solved doing a factory reset. Now even a factory reset did not work anymore.

@Palazz,

It is great to have you back and your patience is greatly appreciated.

If you have followed all the steps suggested in the article I had shared in my previous post and the issue persists, then it might be a hardware issue.

I recommend you contact HP phone support to further diagnose the issue.

Here is how you can get in touch with the phone support.

1)Click on this link - www.hp.com/contacthp/

2)Select the product type.

3)Enter the serial number of your device or select let HP detect your product option.

4)Select the country from the drop-down.

5)You should see the HP phone support number or Chat option listed.

Good day! Take care 🙂

Cheers!
