A target, method, and apparatus are disclosed for measuring assembly and alignment errors in scanner sensor assemblies. The sensor assembly comprises at least two sensor segments. The target comprises edges defined by changes in reflectance. At least one vertical edge corresponds to each sensor segment, and can be detected only by its corresponding segment, even when the segments are misaligned to the maximum extent of their placement tolerances. The target may optionally comprise a horizontal edge spanning the sensor segments. The target is scanned, and the resulting digital image is analyzed to detect the apparent locations of the target edges. The apparent edge locations provide sufficient information to locate the sensor segments. The target may optionally be incorporated into a scanner, or into a separate alignment fixture. The analysis may be performed in a scanner, in a fixture, or in a host computer attached to a scanner or a fixture.

A tuning methods of an External Cavity Laser Diode (ECLD), comprises steps of: (1) providing a laser light to a grating so as to tilt the grating to an optical axis of a collimated laser light, (2) adjusting the orientation of the grating relative to the collimated laser light, (3) monitoring singleness of longitudinal mode and optical power of a light emitted from the grating, (4) calculating an orientation of the grating to exhibit intended optical power at which the singleness of longitudinal mode shows at least predetermined value, (5) adjusting the grating orientation or the optical axis of the collimated laser light to the calculated grating orientation.

An object plane detection system comprises a light source adapted to illuminate a media object to generate an image area on a photosensitive sensor. The system also comprises a detection module adapted to determine a location of an object plane corresponding to the media object based on a size of the image area.

A sheet support tray having an upstream end portion, a downstream end portion and a sine wave shaped sheet support portion extending between the end portions and having at least one crest and two troughs, which is adapted to cause at least the trailing edge portion of a sheet having curled ends to lie relatively flat in the tray to avoid paper jams with the leading edge of an incoming sheet. Structure for facilitating grasping of a sheet in the tray is also described.
