If you bought the printer in one region and moved to a new region you need to call customer support to request a "Regionalization Reset". There should not be any charge for this; it is covered as part of the cartridge warranty. You will need to have access to your computer and printer while on the line with HP. You will also need to have a set of cartridges for the new region, once the reset is complete cartridges from the original region will no longer work. Check out the following document about regionalization.
