Abstract

Systems and methods for identifying a single failure in a heater array and compensating for the failure are described. The methods include identifying two X buses and two Y buses of the heater array having a location of the failure. A confirmation of the single failure within the heater array is performed after identifying the two X and two Y buses. Once the single failure is confirmed, the location of the failure is identified. The methods include compensating for the single failure by adjusting a duty cycle of a heater at the location of the failure, adjusting additional duty cycles of heaters along the same X bus as the failed heater and the same Y bus as the failed heater, and maintaining remaining duty cycles of power provided to remaining heaters of the heater array.
