Abstract:
1. An inkjet apparatus comprising: an inkjet head assembly and a capping assembly movable relative to each other between a first position in which the inkjet head assembly is capped and a second position in which the capping assembly is clear of the inkjet head assembly; an activatable first switch for, when activated, providing a first signal indicative of the inkjet head assembly and the capping assembly approaching one of the first and second positions; an actuatable stepper motor for (i) moving the inkjet head assembly and the capping assembly toward the first position when the stepper motor is actuated to operate in a first direction, and (ii) moving the inkjet head assembly and the capping assembly toward the second position when the stepper motor is actuated to operate in a second direction which is opposite the first direction; and a controller for (i) detecting presence of the first signal from the first switch, and (ii) controlling the stepper motor such that the inkjet head assembly and the capping assembly continue to move relative to each other a first previously learned distance towards the one of the first and second positions upon the first signal from the first switch being detected.
