Abstract
A method for scanning an object, for example a document, by an image scanner is disclosed. The method comprises performing an initial scan of the object by displacing a carriage carrying a light source and at least one photosensitive device from a home position to an end position and performing a final scan by then displacing the carriage from the end position to the home position.
Claims16
A method for scanning an object by an image scanner, comprising:
- performing an initial scan of the object by displacing a carriage carrying a light source and at least one photosensitive device from a home position to an end position;
- and
- performing a final scan by then displacing the carriage from the end position to the home position.
An image scanner, comprising:
- a platen;
- a carriage disposed below the platen and having a displacement axis substantially parallel to the platen;
- a light source and at least one photosensitive device disposed on the carriage;
- and
- the carriage having a displacement from a home position to an end position along the displacement axis in an initial scan operation to provide an initial image of an object on the platen and a subsequent displacement from the end position to the home position in a final scan operation to provide a final scanned image of the object, wherein the carriage does not return to the home position between the initial scan operation and the final scan operation.

- a platen;
- a carriage disposed below the platen and having a displacement axis substantially parallel to the platen;
- a light source and at least one photosensitive device disposed on the carriage;
- and
