ABSTRACT:
An algorithm for preliminary firing of ink droplets through inkjet nozzles prior to inkjet printing operation is disclosed. According to this algorithm, a calculation is made of a scheduled time of a next nozzle-cleaning operation which succeeds a time instant at which a last firing operation was implemented, by a predetermined reference-time-interval, and an operation is performed concerning a reduction in a frequency at which the nozzle-cleaning operation is repeated, by monitoring the calculated scheduled-time of nozzle-cleaning operation, on a time-line basis.
