Abstract
With the purpose of providing an improved cleaning mechanism that accomplishes better results and that may be used in thermal and piezoelectric printing, it is dis-closed a method for cleaning a printhead comprising: moving a wiper along a plurality of nozzles of the printhead; and pressurizing the nozzles within the printhead, the pressurization of each nozzle causing ink to be expelled in an expelling direction; wherein a controller is to detect the position of the wiper and to selectively pressurize at least some of the nozzles for which the position of the wiper corresponds to its expelling direction.
