Method and System for Improving Output Quality of Image Forming Devices

An image forming device for producing one or more images of one or more documents, the image forming device comprising:

• a transparent surface for supporting the one or more documents;
• a scan bar assembly for scanning the one or more documents;
• a spacer assembly comprising:
• a plurality of spacers located between the scan bar assembly and the transparent surface for providing a gap between the scan bar assembly and the transparent surface;
• and
• a height adjustment mechanism for adjusting the height of at least one of the plurality of spacers, the adjustment of the height of the at least one spacer comprising modifying an angle of inclination of the scan bar assembly relative to the transparent surface, wherein the modification of the angle of inclination of the scan bar assembly improves an output quality of the image forming device.

A system for improving output quality of an image forming device producing one or more images of one or more documents, the system comprising:

• a speckle determination module for determining an amount of speckle in the one or more images;
• a speckle comparison module for comparing the amount of speckle with a predefined amount of speckle;
• and
• an angle estimation module for determining one or more angles of inclination of a scan bar assembly in the image forming device based on the comparison of the amount of speckle, wherein the one or more angles of inclination are used to adjust an angle of inclination of the scan bar assembly relative to a transparent surface of the image forming device for improving the output quality of the image forming device.

An image forming device comprising:

• a transparent surface for supporting one or more documents;
• an image capture assembly for capturing images of the one or more documents, the image capture assembly comprising a plurality of sensor elements which receive light reflected from the one or more documents;
• and
• a support assembly for supporting the image capture assembly relative to the transparent surface, the support assembly supporting the image capture assembly such that a normal to the plurality of sensor elements is at a non-zero angle relative to a normal to the transparent surface.

A computer program product for use with a computer, the computer program product comprising a computer usable medium having a computer readable program code embodied therein for improving output quality of an image forming device producing one or more images of one or more documents, the computer readable program code further comprising:

• program instruction means for determining an amount of speckle for the one or more images;
• program instruction means for comparing the amount of speckle with a predefined amount of speckle;
• and
• program instruction means for indicating whether an adjustment of an angle of inclination of a scan bar assembly in the image forming device is required, based on the comparison, wherein the adjustment of the scan bar assembly improves the output quality of the image forming device.
