Abstract:
1. A printer comprising: a first ink reservoir configured to store liquid ink; a second ink reservoir configured to store liquid ink; a first plurality of inkjet ejectors operatively connected to the first ink reservoir to enable the first plurality of inkjet ejectors to eject ink received from the first ink reservoir; a second plurality of inkjet ejectors operatively connected to the second ink reservoir to enable the second plurality of inkjet ejectors to eject ink from the second ink reservoir; a pressure source operatively connected to the first ink reservoir and the second ink reservoir, the pressure source being configured to pressurize ink in the first ink reservoir to one of a first and second pressure and to pressurize ink in the second ink reservoir to one of the first and the second pressure; a first wiper positioned at a location that enables the first wiper to contact a face of the first plurality of inkjet ejectors; a second wiper positioned at a location that enables the second wiper to contact a face of the second plurality of inkjet ejectors; a single actuator operatively connected to the first wiper and the second wiper to move at a same time the first wiper into contact with the first plurality of inkjet ejectors and to move the second wiper into contact with the face of the second plurality of inkjet ejectors; and a controller operatively connected to the single actuator and the pressure source, the controller being configured to operate the pressure source to apply the first pressure to the first ink reservoir for a first period of time and then apply the second pressure to the first ink reservoir and the second ink reservoir for a second period of time and to operate during the second period of time the single actuator to move the first wiper into contact with the face of the first plurality of inkjet ejectors and to move the second wiper into contact with the face of the second plurality of inkjet ejectors to enable the first and the second wipers to be moved across the faces of the first plurality of inkjet ejectors and the second plurality of inkjet ejectors while the pressure source applies the second pressure to the first plurality of inkjet ejectors and the second plurality of inkjet ejectors during the second time period.
