About the printhead

The printhead, which is supplied installed in the printer, is connected to the ink cartridges and jets ink onto the paper.

CAUTION: Observe precautions when handling the printhead, because it is an ESD-sensitive device (see the Glossary on page 143). Avoid touching pins, leads, and circuitry.
