Printheads
The printheads are connected to the ink cartridges. They use jet action to put ink on the paper. Each
printhead has two ink cartridge connection points and two jet nozzles, which means that each printhead
accommodates two ink cartridges. For example, the following printhead image indicates a printhead that
draws and jets ink from the magenta and yellow cartridges.
The Printheads are extremely durable and do not need to be replaced every time an Ink Cartridge is replaced.
They are independent of the Ink Cartridges and will continue giving excellent image quality results even if the
Ink Cartridges are low on ink.
If you notice a decline in print quality such as lines or dots missing from text/graphics, go to
Initial print-
quality troubleshooting actions on page 138.
The following table lists the Printheads for the HP Designjet T7200 printer series.
