Abstract:
Color printing apparatus for compensating for lateral distortion of a re-inkable belt, the re-inkable belt being moveable along an endless path and trained about a transport roller and a platen roller including an ink transfer layer wherein ink is transferred by the actuation of a print head to a moveable receiver and replenished in the endless belt comprising:a) means for causing the moveable receiver to move into ink transfer relationship with the re-inkable belt at a nip position between the platen roller and the print head for transferring ink imagewise from the re-inkable belt to the receiver;b) means for replenishing depleted ink on the re-inkable belt; andc) means including two spaced actuators which when actuated adjustably applying tension at two spaced locations to the print head to laterally displace the re-inkable belt, a sensor for determining the position of the re-inkable belt, and means coupled to the sensor for selectively actuating the spaced actuators so as to laterally position the re-inkable belt along the surface of the platen roller to compensate for lateral distortion of the re-inkable belt.
