I had reported on this topic in the German article HP blockt Dritthersteller-Tintenpatronen per Firmware-Update and in other articles (see article links at the end of the article). Anyone using new third-party ink cartridges also received this error message. The printer driver reports that the ink cartridge is defective or damaged. People using third-party or refillable ink cartridges received an error message. From this date on, third-party ink cartridges were no longer accepted for certain HP printer models. As of September 13, 2016, the time bomb in the firmware became active. HP had released a firmware update for several inkjet office printers on March 12, 2016.

In September 2016, it became known that HP had started to block third-party ink cartridges with a firmware update.

This manufacturer has a long tradition of making third-party ink tanks in HP printers unusable by secret firmware updates.
