Abstract
An apparatus for maintaining an inkjet printer printhead in a working state, the printer defining an array of orifices from which in use jets of ink are projected. The apparatus may have a means for applying a pressure pulse to ink with the printhead sufficient to discharge ink from each orifice when not in use to project ink. The pressure pulse may have a relatively rapidly rising leading edge and a relatively slow falling trailing edge.
