Abstract:
A method of calibrating a wiper position in an ink jet printer having a nozzle plate and a wiper arranged to wipe the nozzle plate, the nozzle plate having a number of nozzles each of which is in fluid communication with a pressure chamber, each pressure chamber having an actuator for exciting a pressure wave in a liquid in the pressure chamber, and a detection system arranged to detect pressure fluctuations in the pressure chamber includes adjusting the wiper to a position in which it is set against the nozzle plate; exciting a pressure wave in at least one of the pressure chambers; recording the pressure fluctuations in said at least one pressure chamber; deciding, on the basis of the detected pressure fluctuations, whether the wiper is set correctly against the nozzle that is in fluid communication with said at least one pressure chamber; and correcting the position of the wiper if necessary.

Claim (Index 8):
An ink jet printer having a nozzle plate and a wiper arranged to wipe the nozzle plate, the nozzle plate having a number of nozzles each of which is in fluid communication with a pressure chamber, each pressure chamber having an actuator for exciting a pressure wave in a liquid in the pressure chamber, and a detection system arranged to detect pressure fluctuations in the pressure chamber, the printer further having a control circuit controlling the actuator, characterized by comprising a processor configured to control the control circuit and the detection system and to perform at least the steps b), c) and d) of the method according to  claim 1 .
