Hello,
I bought my printer in France and I live in France and I use HP903 cartridges so I don't have to change the region.
I already performed a firmware update and my vesion is MCP2CN1716AR
My problem is always the same
my printer doesn't accept non original cartridges HP903 a meesage is displayed in french on the screen :
Cartridges problem, remove and reinstall the cartridges
It looks like the dynamic secirity is alwas activated
If I put my same non original cartridges HP903 in 2 other HP 6970 printer bought in the same time in France,
my non original cartridges HP903 are accepted, so my cartridges are functional
and I think only my print HP6970 is out of order.
I want to activate the warranty.
Thanks
