Claim 12:
13. A method comprising:
supporting a print agent applicator at a load point on a mount;
applying a driving force from an actuator at an actuation point on the mount;
guiding the mount and supported print agent applicator under the driving force, by a guide mechanism, to translate along a predetermined path towards a printing drum;
forming an engaging contact between the supported print agent applicator and the printing drum for print agent to be transferred from the supported print agent applicator to the printing drum;
determining, via a sensor, a position parameter indicative of the position of the supported print agent applicator;
monitoring, via a controller, the position parameter and controlling respective actuators of positioning devices to control the position of the mount and the supported print agent applicator relative to the printing drum in response to the position parameter;
determining, via a second sensor, a force parameter indicative of the driving force or an engaging force applied by the supported print agent applicator on the printing drum when the supported print agent applicator and printing drum are in engaging contact; and
monitoring, via a second controller, the force parameter and controlling the respective actuators of the positioning devices to control the driving force and/or the engaging force in response to the force parameter.
