Abstract

Disclosed is a printing plane adjusting mechanism for a typewriter or similar machine wherein a paper handling system including a platen defining the printing plane is finely as well as coarsely adjustable by a single lever relative to a printing element to establish a predetermined normal distance between the printing plane and printing element or varied distances other than normal to accommodate paper packs of varying thickness. Adjustment of the normal distance or gap is effected without loosening or tightening screws.
