HP exploits firmware update to make its printers reject third-party ink
Back in March of 2016, millions of Inkjet and Inkjet Pro owners were issued a fake “security update” by the company that sat dormant on their printers for six months until it began to reject third-party ink. HP owners were quick to voice their negative opinions over the company’s shady tactics and almost 15,000 complaints were received.
The company eventually released a statement in which it apologised and provided a link to a firmware update that restored third-party ink functionality to the affected printers.
A new firmware update for the company’s Officejet printers appears to be identical to the notorious update released last year. Now when users attempt to load their printers with third-party ink they receive a message which reads:
“One or more cartridges appear to be damaged. Remove them and replace with new cartridges.”
Depending on the number of cartridges used by your particular printer, you may be able to use a few third-party cartridges without receiving the error but filling all of the slots completely will trigger the error and display the warning message.
So far the HP OfficeJet 6800 series, OfficeJet Pro 6200 series, OfficeJet ProX 450 series, OfficeJet Pro 8600 series and more have been affected by the new firmware and HP has not yet commented on the issue.
