An ink jet printhead voltage fault protection apparatus includes a power supply and a latching circuit. The latching circuit disables a printhead voltage applied to the printhead by the power supply upon detection of a fault condition associated with the printhead voltage such that the printhead voltage remains disabled until the power supply goes through a power-on reset sequence.
