Abstract
An air fan assembly includes a suction box including a wall having an open area distributed across the wall. The suction box is configured to contain an underpressure on an inner side of the wall, so as to cause a cut sheet to adhere to a perforated transport belt. An impingement unit is configured to expel air supplied thereto towards the perforated transport belt. An air fan is arranged to create and maintain the underpressure in the suction box and to supply the air to be expelled by the impingement unit via an air outlet of the suction box. A first valve is arranged upstream of the air fan for conditionally admitting an additional air flow into the suction box. An inkjet printer and a method of operating the air fan assembly include the air fan assembly.
