Patent attributes
An apparatus is provided for adjusting the printhead-to-media spacing in a printer having a printhead carrying carriage, which is rockable relative to an elongate carriage rod in the printer to effect a change in such spacing. The apparatus comprises an anti-rotation rail having a primary axis, the anti-rotation rail configured to have the carriage mounted thereon to be rotatable about the primary axis. A carriage guiding block is configured to be mountable on the carriage rod and configured to have the printhead carrying carriage mounted thereon. An actuator is mounted on the carriage guiding block, the actuator movable between a spacing position in which the actuator is arranged to provide a first predetermined separation between the carriage guiding block and the printhead carrying carriage, to provide a first printhead-to-media spacing value, and a retracted position in which the actuator is arranged to provide a second separation between the carriage guiding block and the printhead carrying carriage, to provide a second printhead-to-media spacing value.
