Abstract
A method responds to an over-temperature condition in a printhead. The method includes generating a first electrical signal corresponding to a temperature in a printhead, monitoring the first electrical signal with a first electronic circuit to terminate delivery of electrical power to a printhead in response to detection of a safety event, and monitoring the first electrical signal with a second electronic circuit to regulate an amount of electrical power delivered to the printhead.
