Abstract
Disclosed is a method of adjusting a scanner for scanning of an original, the scanner comprising an image sensor and a light source for emitting light, the method comprising the steps of: a) moving the image sensor in order for it to be located at a predefined scanning position by means of a movable mechanical member; b) determining the difference between the scanning position and the predefined scanning position; where the method further comprises: determining the difference between the scanning position and the predefined scanning position by detecting radiation from at least one fix-point having a fixed position relative to the image sensor.
Claims15
A method of adjusting a scanner for scanning of an original, the scanner comprising an image sensor and a light source for emitting light, the method comprising the steps of:
- a) moving the image sensor in order for it to be located at a predefined scanning position by means of a movable mechanical member;
- b) determining the difference between the scanning position and the predefined scanning position;
- where the method further comprises:
- determining the difference between the scanning position and the predefined scanning position by detecting radiation from at least one fix-point having a fixed position relative to the image sensor.
A scanner for scanning of an original, the scanner comprising:
- an image sensor;
- a light source for emitting light;
- a movable mechanical member for moving the image sensor in order for it to be located at a predefined scanning position;
- means for determining the difference between the scanning position and the predefined scanning position;
- and
- means for detecting radiation from at least one fix-point having a fixed position relative to the image sensor for determining the difference between the scanning position and the predefined scanning position.
