Abstract
An image forming apparatus includes a fiducial reference point sensor that individually monitors the position of first and second fiducial reference points on a moving print device that are in spaced relation to one another.
Claims31
An image forming apparatus, comprising:
- a movable print device;
- at least first and second fiducial reference points on the movable print device in spaced relation to one another;
- and
- a fiducial reference point sensor that individually monitors the position of the first and second fiducial reference points.
A scanning carriage for use in an image forming apparatus, the image forming apparatus including at least one cooperative element sensor, the scanning carriage comprising:
- a main body configured to at least one printer element;
- and
- at least first and second cooperative elements carried by the main body in spaced relation to one another.
An image forming apparatus, comprising:
- a print device, including a carriage and a plurality of printer elements supported on the carriage, movable along a scan axis;
- at least first and second cooperative elements carried by the print device in spaced relation to one another;
- a cooperative element sensor;
- and
- a controller, operably connected to the printer elements and the cooperative element sensor, that controls the operation of a first group of printer elements at least partially in response to data obtained by monitoring the first cooperative element with the cooperative element sensor and controls the operation of a second group of printer elements at least partially in response to data obtained by monitoring second first cooperative element with the cooperative element sensor.
A method of operating a print device having first and second fiducial reference points in spaced relation to one another, the method comprising the steps of:
- moving the print device;
- and
- individually monitoring the position of the first and second fiducial reference points.
