Handling ink cartridges and printhead- HP DesignJet T730/T830 MFP

Ink cartridges store the ink and are connected to the printhead, which distributes the ink on the paper.

To purchase additional cartridges, see Accessories.

Each ink cartridge contains a memory chip that assists in the operation of the printer.

The 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 pages printed using the cartridge, the page 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 data 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: go to the HP website at the following link: 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 data. Any third party possessing the cartridge may be able to access 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 turn off the memory chip's ability to collect printer usage information. To do so, access the Embedded Web Server, and select Settings > 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.

You can check the status of your ink cartridges (how much ink is remaining, for example) at any time.

To view the ink levels of your ink cartridges, touch the Dashboard status  on the front panel and touch the ink icon . Then touch the desired ink level for more information.

For an explanation of the ink cartridge status messages, see Ink cartridge status messages.

if you touch Replace Inks, the printer will give you step-by-step instructions to replace the ink cartridges. See Replace an ink cartridge for more information.
