ABSTRACT:
A printer mechanism including a frame, a platen, a printhead, a compensator mechanism supported on a frame and movable relative thereto to compensate for print media of various thicknesses, a drive motor for driving the printhead rotatable in the first direction to drive the printhead and rotatable in the second direction and a sector gear connected to the compensator mechanism for effecting movement of the compensator mechanism to move the platen supported thereby away from the printhead. The drive motor when rotated in the second direction is effective to drive the sector gear to move the compensator mechanism to move the platen to a position in which it is spaced apart from the printhead.
