Data stored on the print cartridge
The HP print cartridges used with this product contain a memory chip that assists in the operation of the
product.
In addition, this memory chip collects a limited set of information about the usage of the product, which
might include the following: the date when the print cartridge was first installed, the date when the print
cartridge was last used, the number of pages printed using the print cartridge, the page coverage, the
printing modes used, any printing errors that might have occurred, and the product model. This
information helps HP design future products to meet our customers' printing needs.
The data collected from the print cartridge memory chip does not contain information that can be used
to identify a customer or user of the print cartridge or their product.
HP collects a sampling of the memory chips from print 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 products. HP partners who assist in recycling this
print cartridge might have access to this data, as well.
Any third party possessing the print 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 memory chip cannot be used in an HP
product.
