Various embodiments disclose a method for operating a printer apparatus. The method comprising monitoring a utilization rate of each heating element in a first set of heating elements defined by a print head arrangement. Further, the method comprises generating a utilization dataset based upon monitoring of the utilization rate of each heating element in the first set of heating elements print head arrangement. Furthermore, the method includes analyzing the utilization dataset to identify one or more overutilized heating elements of the first set of heating elements. Additionally, the method includes identifying a second set of heating elements defined by the print head arrangement. The second set of heating elements comprises a portion of the first set of heating elements exclusive of the one or more overutilized heating elements. The method further includes processing a print job. The processed print job utilized the second set of heating elements during printing.
