Shuttle Drive Motor
285
While the hammer is in flight the coils are de-energized and their magnetic
field collapses, restoring the magnetic attraction of the permanent magnet in
the hammer bank. After striking the ribbon and paper, the hammer rebounds
and is recaptured by the permanent magnet. When the shuttle reaches the
end of a sweep, it reverses direction, the paper is micro-stepped upwards one
dot row, and the hammer springs print the next row of dots as the shuttle
sweeps in the opposite direction. All this happens extremely rapidly: hammer
re-firing in a 2000 lpm printer, for example, takes about 419 microseconds,
with the vertical paper movement between dot rows occurring in 2.10
milliseconds.
Paper Transport System
Figure 58. Paper Transport System
A two-phase DC stepper paper feed motor, directed by the engine controller
(EC) on the controller board, drives two tractor sprockets by means of a
toothed belt linked to a pulley on the splined shaft. The stepper motor permits
extremely accurate vertical paper movement in 1/72 inch increments. This
drive configuration is designed for continuous, fan-folded paper from 3 to 17
inches wide and 1 to 6 sheets thick. To reverse paper movement (that is,
move it downward) a second motor opens and closes the platen by means of
a toothed belt linked to a pulley on the platen shaft. Opening the platen
