Abstract
An apparatus for opening a platen in an impact printer is implemented. The apparatus permits rapid loading of a paper supply while maintaining the required tolerance in the spacing of the platen and a printhead. The mechanism also accommodates the printing of form documents in which the thickness of the document material may be variable. The mechanism adjusts to the varying thickness of the document medium while maintaining the required tolerance in the spacing between the platen and printhead.
