Abstract
Crack detection circuits for printheads are described. In an example, a crack detection circuit for at least one printhead, includes: crack detectors formed on the at least one printhead; switches selectively coupling the crack detectors on each printhead to a communication bus; and a configuration circuit on each printhead coupled to control inputs of the respective switches, each configuration circuit responsive to a crack detection configuration input to control the respective switches.
