Abstract: In a method for initializing an image scanner having a scanning module and an automatic document feed (ADF) glass, the scanning module is moved in a forward direction toward the ADF glass to search for a reference mark located within a relatively close proximity to the ADF glass. The scanning module is moved forward to search for a black-white transition in response to the reference mark being located and the scanning module is moved in a backward direction away from the ADF glass in response to the black-white transition being located. The scanning module is stopped when the image sensor of the scanning module is aligned with an origin mark to thereby accurately position the scanning module.

The optical sensor is transported to a position above a marker provided on the tray. Light is emitted from the photo emitter to irradiate the marker. Light reflected from the marker is received by the photo receiver. A reference value is determined based on a first value of the first signal outputted when the marker is irradiated. A predetermined calculation is executed with respect to the reference value to determine a threshold value. The optical sensor is transported above the tray, while emitting light from the photo emitter and comparing the first signal outputted from the photo receiver with the threshold value. A position of the marker is identified based on the comparison of the first signal and the threshold value. It is determined a position at which the printing begins based on the identified position of the marker.
