Change region codess on printer hp c3180
I have just moved from the US to Shanghai with my HP C7280 printer. Bought some new cartridges from the HP dealer in Shanghai after our US supply ran out. Got the 'Incorrect Ink Cartridge' message on the printer after installing them, which the dealer probably knew I would get and didn't tell me, which I'm assuming is what you got.
My experience was to use the 'Chat' function on the HP.com web site in the Support area. The good news is that they solved my problem, the bad news is that it took 1 1/2 hours and is the most convoluted process I've experienced in years. There is a little 'voodoo' going on the background......... after having me find several values, including cartridge serial number values (no not the cartridge number on the cartridge), reset values, and others I can't remember, he said he had to go 'calculate' and he then came back with 5 four digit numbers I had to enter after going to Windows Control Panel -->Printers and after getting my printer selected and the Preferences screen displayed, clicking on the HP logo while holding the CRTL key down (I kid you not).
Sooooooo, I believe the only solution is to use HP Support and to also write letters complaining about how really, really, really stupid this process is. And being the conspiracy theorist that I can be, HP probably was seeing lost revenue from people buying cartridges that are cheaper in parts of the world and shipping them to where HP is, ahem, making a killing and padding their profits.......
