PRINTHEAD HAVING MULTIPLE PRINTHEAD DIES WITH CRACK SENSE RESISTORS FOR CRACK SENSING AND A METHOD FOR DETECTING CRACKS

摘要

In an example, a printhead (102) comprises a plurality of printhead dies (114), each printhead die including at least one crack sense element (120); and at least one analog bus (150) connected to each printhead die, the at least one analog bus to deliver a known current to at least one crack sense element and to output a voltage to allow a controller to determine whether at least one of the printhead dies is cracked based on the voltage.
