Character Formation
The MVP–Series printers generate characters by accumulating groups of dots
in matrices. Dot impressions are made by an assembly of 17 hammers
installed on an oscillating shuttle that impact the paper through a moving ink
ribbon. Synchronized horizontal shuttle movement and vertical paper
advancement produce overlapping dots that form solid characters
(Figure 1–1).
