Mechanics
The Lettera 32 is a downstrike typebars typewriter. The typebars strike a red/black inked ribbon, which is positioned between the typebar and the paper by a lever whenever a key is pressed; a small switch located near the upper right side of the keyboard can be used to control the strike position of the ribbon, in order to print with black, red, or no ink (for mimeograph stencils).
Ribbon movement, which also occurs at every keypress, automatically reverses direction when there is no ribbon left on the feed reel; two mechanical sensors, situated next to each wheel, move when the ribbon is put under tension (indicating ribbon end), attaching the appropriate wheel to the ribbon transport mechanism and detaching the other.
