Abstract
A method for printing with a laser printer includes obtaining data representative of the bow and tilt characteristics of the printer. Data representing an image to be printed is loaded and analyzed. A control signal is determined from the image data and modified based on the known bow and tilt characteristics of this printer, such that the printed image is free of bow and tilt.
Claims23
A method of printing using a laser printer comprising:
- determining bow and tilt in a beam path of a laser;
- processing image data representative of an image;
- developing a laser control signal representative of the image;
- and
- altering the control signal to compensate for the bow and tilt in the beam path.
2 more elements
A laser printer comprising:
- at least one laser assembly in optical communication with a drum assembly, the at least one laser assembly configured to emit a laser beam onto the at least one drum assembly;
- wherein the laser beam is generated in response to a plurality of control signals that are configured to compensate for laser beam bow and tilt.
