Method of cleaning nozzle surfaces of an inkjet print head assembly

A method for cleaning nozzle surfaces of an inkjet print head assembly. the method comprising:

• providing a cleaning slide including an ultrasonic cleaning device, a suction device, and a rinsing device;
• using the cleaning slide to carry out a movement along the assembly and clean the nozzle surfaces with a cleaning liquid in ultrasonic vibration;
• carrying out the movement of the cleaning slide with a forward movement and a backward movement;
• during the forward movement, activating the ultrasonic cleaning device and activating the suction device following the ultrasonic cleaning device, while keeping the rinsing device deactivated following the two;
• during the backward movement, activating the rinsing device and activating the suction device following the rinsing device, while deactivating the ultrasonic cleaning device following the two;
• emitting a rinsing liquid from the activated rinsing device;
• and
• during the backward movement, using the suction device to aspirate the rinsing liquid of the rinsing device and also aspirate the cleaning liquid and contamination off of the nozzle surfaces.
