I have had an HP Officejet 73100 All In One printer since 2007 and have in all that time have used HP genuine print cartridges. But recently the cost is up to £80.00 to replace both colour and B&W cartridges.
So I have for the past few months been using remanufactured ones at a total typical cost of around £28.00 the pair, with to my eyes just as good quality.
However, one day recently my printer stopped working and small HP box presented itself on my screen saying something like "Non compatible cartridge detected, please click here to continue..."
Being in the middle of something and busy, like a fool I did. The printer then locked completely and would not work again until I installed the very expensive HP cartridges. In fairness to my supplier they refunded the cost of my refills.
I have spent time uninstalling all the printer software and then trying to reinstall from the original discs, but they would not, so have had to reinstall all downloaded form the HP site, and am about to try some again using the remanufactured cartridges. We shall see...
My suppliers advice is if this box appears IGNORE IT and then press and hold down the cancel button on your printer until the message disappears.
The irony of it is I had my printer serviced recently and the engineer told me they have stopped making spares for my machine!!!
