Where are you located? If you are in Thailand the cartridges you need will be the 60 series. If you are in India the cartridges you need will be the 818 series.
If you purchased the printer in Thailand and moved to India you will need to Contact HP 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. HP's web page on the subject is here.
If you are still in Thailand you will need to order HP 60 cartridges, the 818 cartridges will not work for you.
