Abstract
Methods and apparatus are disclosed for utilizing an inter-page gap for producing calibration patches, which utilization can reduce or eliminate interruption or suspension, due to calibration, of the normal printing mode of a color laser printer. In one embodiment of the present invention, an apparatus is provided which is configured to produce at least one calibration patch within each of a plurality of successive inter-page gaps. In accordance with another embodiment of the present invention, a method is disclosed which provides for producing at least one calibration image within an inter-page gap and further includes producing at least one calibration patch within each of a plurality of successive inter-page gaps.
Claims20
A method of calibrating an image-producing device, the image-producing device having a movable surface, the method comprising producing at least one calibration patch within an inter-page gap on the movable surface.
A method of calibrating an image-producing device, the image-producing device having an intermediate transfer device, the method comprising:
- producing an output image on the intermediate transfer device during a first revolution thereof, wherein the output image comprises a first toner;
- and,
- producing at least one first calibration patch within an inter-page gap on the intermediate transfer device during the first revolution thereof, wherein the at least one first calibration patch comprises the first toner.
An image producing apparatus comprising:
- an intermediate transfer device;
- an image-producing portion which is configured to produce at least one calibration patch on the intermediate transfer device;
- and,
- a calibration algorithm configured to cause the image-producing portion to produce at least one calibration patch within an inter-page gap.
