Abstract
A method for servicing a printhead of an inkjet printing mechanism is provided. Firstly, a plurality of time difference information is collected by the printing mechanism. Each time difference information represents a period of time passed between end of a last print job and receipt of a succeeding print job. The print jobs are sent from a computer connected to the printing mechanism. Subsequently, the printing mechanism uses the plurality of time difference information to determine a nominal time information representing an amount of time. After the determination of the nominal time information, the printing mechanism periodically performs a first level servicing dependent upon the nominal time information.
