Storage of anonymous usage information
Each ink cartridge contains a memory chip that assists in the operation of the printer. In addition, this
memory chip stores a limited set of anonymous information about the usage of the printer, which can include
the following: the date when the cartridge was first installed, the date when the cartridge was last used, the
number of prints printed using the cartridge, the print coverage, the frequency of printing, the printing
modes used, any printing errors that may have occurred, and the product model. This information helps HP to
design future products to meet our customers' printing needs.
The information collected by the memory chip does not include information that could be used to identify a
customer or user of the cartridge or printer.
HP collects a sample of the memory chips from ink cartridges returned to HP's free return and recycling
program (HP Planet Partners:
http://www.hp.com/hpinfo/globalcitizenship/environment/recycle/ ). The
sampled memory chips are read and studied in order to improve future HP products.
HP partners who assist in recycling ink cartridges may also have access to the information. Any third party
possessing the cartridge may be able to access the anonymous information on the memory chip. If you prefer
not to 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 tell the printer not to store the
information in the memory chip. To do so, access the Embedded Web Server, and select Setup > Anonymous
Usage Information Storage. This does not prevent the cartridge from working normally in other respects.
However, if you change your mind later, you can restore the factory defaults to resume collecting printer
usage information.
