Abstract
An image processing apparatus (,) comprises an imaging drum (,) for holding print media (,) and donor material (,) in registration on the imaging drum (,). A print head (,), driven by a lead screw (,) and stepper motor, moves along a line parallel to a longitudinal axis (X) of the imaging drum (,) as the imaging drum (,) rotates. The print head (,) is brought repeatably to a mechanical registration position using sensors. For coarse positioning, the print head (,) is moved to a first linear sensor position, with the drive motor operated in full-step mode. For fine positioning, the drive motor is then operated in microstepping mode, during which a second sensor detects rotational orientation by detecting a rotational indicator mounted on the lead screw (,). The rotational indicator permits straightforward adjustment for fine-tuning, being adjustable to any one of a number of fixed positions relative to lead screw rotation.
