Abstract
A variable maximum operating temperature for a printhead is defined and utilized within both a system and a method. The variable maximum operating temperature varies according to one or more operating conditions within a printer into which the printhead may be installed. If a detected temperature of the printhead is greater than the variable maximum operating temperature for a detected operating condition, the printer will be shut down to prevent overheating. Accordingly, the system and method extend the useful life of the printhead and reduce paper waste.
