Chapter 8
HP collects a sampling of the memory chips from cartridges returned to HP's free return and recycling program (HP Planet Partners: www.hp.com/recycle). The memory chips from this sampling are read and studied in order to improve future HP printers. HP partners who assist in recycling this cartridge might have access to this data, as well.
Any third party possessing the cartridge might have access to the anonymous information on the memory chip. If you prefer to not allow access to this information, you can render the chip inoperable. However, after you render the memory chip inoperable, the cartridge cannot be used in an HP printer.
If you are concerned about providing this anonymous information, you can make this information inaccessible by turning off the memory chip's ability to collect the printer's usage information:
To turn off usage information collection
1.On the printer control panel, touch 
(right arrow), and then touch Setup.
2.Select Preferences, and then select Cartridge Chip Information.
3.Touch OK to turn off usage information collection.
NOTE: If you turn off the memory chip's ability to collect the printer's usage information, you can still continue to use the cartridge in the HP printer.
