Excitation Sequence
As shown in
Table 3-4
, the printer feeds paper in the normal direction when the motor is excited
in the order of step 1, step 2, step 3, step 4, step 1, step 2, . . . . On the other hand, to rotate the
motor in a reverse direction, drive the motor in the reverse order of: step 4, step 3, step 2, step
1, step 4, step 3, . . . .
