Armor printing on HP printer connected to R7000 FW: V1.0.11.110_10.2.100

after I've enable Armor on R7000 (firmware V1.0.11.110_10.2.100) the SW periodically print 3 pages on HP ENVY 5000 with HP InstantInk subscription.

I've removed the printer from Armor so many time but Armor always add and when I forgot to remove again it start printing again. consuming pages from my HP Account.

I read other users has the same problem and the "solution" is update FW; but this seems to be the latest version of the Firmware.

Could you please let me know what to do to solve the issue?

thanks
