As required by the character pattern, each wire
can strike the ribbon up to four times per char-
acter (for example, print wire 5 when printing
the character A) .
When printing, magnets are not fired at successive
emitter pulses (because time is required to restore
the magnet armatures-at least one emitter pulse
must intervene between firings of the same wire),
and no more than 25 dots are allowed per
character.
Three emitter pulses are used for the space be-
tween the characters.
