Hewlett Packard (HP) has released a new firmware for the printers by Officejet which appears to prevent the use of ink from third-party manufacturers.
The company caused the sallow one year ago when a firmware was released for some of its printers, which prevented the use of ink from non-cassettes HP. 
HP has released an updated version software a month later that restored all functions and allowed third-party printer inks.
The new firmware update of Hewlett Packard that was released on September 13, 2017 looks like an exact copy of the firmware update that was released a year ago (exactly the same day).
Printers show the following error message after installing the new firmware in the printer:
One or more cartridges appear to be damaged. Remove and replace with new cassette.
Affected printer models include printers: HP OfficeJet 6800 Series, HP OfficeJet Pro 6200 Series, HP OfficeJet Pro X 450 Series, HP OfficeJet Pro 8600 series and many other models.
However, it seems that denial of inks that do not belong to the company from HP printers is due to a feature called Dynamic Security.
Tο Support page της HP "HP Inkjet Printers - Dynamic Security Feature Affecting Cartridges Using Non-HP Security Chip" δίνει οδηγίες για το πως να απενεργοποιήσετε το Dynamic Security και η απαγόρευση των μελανιών από τρίτους θα σταματήσει.
After that, you have two options to avoid future problems:
Block it automatic update to your Hewlett Packard printer.
or Change printer company
