Updated HP 301 Ink Cartridges

Introduction Beginning in May 2012, HP is updating the following ink cartridges: HP 61, HP 301, HP 122 and HP 802. The updated ink cartridges are compatible with both current and future printers that use these cartridge numbers. They have been designed in conjunction with future printers to deliver new features. The cartridges available prior to spring 2012 will not be compatible with some printers and All-in-Ones released in 2013. A list of printers compatible with these cartridges will be available in 2013. Do I have the updated cartridges? It is easy to figure out if you have the updated version of these cartridges: If the cartridge is still in the packaging, find the Warranty Ends date on the back of the package. If there is a ‘v1’ several spaces to the right of the date, then the cartridge is the updated version. Figure 1: Cartridge packaging 1 - Warranty Ends date If the cartridge has been removed from the packaging and opened, check the Warranty Ends date on the cartridge. HP 61 and HP 802: if the Warranty Ends date is 2014/04/01 or later, then the cartridge is the updated version. HP 122 and HP 301: if the Warranty Ends date is 2014/07/01 or later, then the cartridge is the updated version. Figure 2: Cartridge 1 - Warranty Ends date
