PRINTHEAD POSITION CONTROL

摘要

Systems and methods for printhead position control. The system comprises a controller that identifies a target distance for moving a printhead in a lateral direction to compensate for lateral shifts in a web of print media as the web travels in a continuous-forms printer in a conveyance direction. The controller also identifies a maximum distance for moving the printhead in the lateral direction based on an allowable print error in a color plane of the printer and one or more previous positions of the printhead. The control further moves the printhead for a distance that is a lesser of the maximum distance and the target distance.

主权项

1. An apparatus comprising:
a controller configured to move a printhead in a lateral direction to compensate for lateral shifts in a web of print media as the web travels in a continuous-forms printer in a conveyance direction; the controller configured to calculate a distance to move the printhead that balances printing alignment within a single color plane with printing alignment in at least two different color planes using at least one printer variable; the controller configured to move the printhead the distance.
