I've been using Officejet 8600 Plus for over 7 years with 3rd party ink cartridges and now after recent update it doesn't work!!! As soon as it is powered on "Printer Failure."
I have tried all the on/off sequences I've seen on the internet. Even put in old empty cartridges that I had, (which did allow the printer to power up properly, but with depleted ink) but as soon as I put in my 3rd party ink, that was working a few days ago, it goes into "Printer Failure." I did Software uninstall/reinstall and the Firmware Updater and nothing helped.
I have a small home business and 2 kids schooling from home due to pandemic. it is unacceptable that HP would completely disable my printer from being used. I will not be forced to buy expensive HP ink, if I buy anything it will be another brand printer.
I need another update ASAP to correct this, there is no way to rollback recent update.
