ABSTRACT:
A rotary capping system services inkjet printheads in an inkjet printing mechanism. A rotary service station has a tumbler with a dual pivoting link that supports a cap platform. The cap platform is gimbal mounted to the link and spring-biased away from the tumbler. The platform has an extending arm that contacts the printhead carriage to align the cap and printhead. When the printhead is positioned for capping, rotation of the tumbler around an axis parallel to the printhead scanning direction brings the platform arm into contact with the carriage. Continued rotation of the tumbler pivots the link and the platform to sweep the cap through a non-linear, generally arcuate path into a capping position at the printhead. The illustrated cap has a multi-ridge lip for sealing over surface irregularities on the printhead nozzle face. A method of sealing inkier printhead nozzles is also provided.
