Abstract
A paper shear includes a flat disk with unsharpened edges pivotally mounted on an assembly carried by the printer carriage. The paper shear is pivoted between paper shearing engaged and disengaged positions relative to a shear platen. The mounting assembly includes a linear actuator and a mounting plate cooperable to pivot the paper shear into the engaged position at an extreme end of carriage travel and maintain it in the engaged position upon movement of the carriage in the opposite direction to shear the paper. The actuator and plate are then relatively displaced at the opposite extreme end of travel to pivot the paper shear into its disengaged position, whereby printing can be resumed.
