Operation
Top and bottom limit of print position is detected by
the vertical registration encoder sensor and the
center sensor.
The center position is detected by the standard
position sensor.
Operation with the Power ON
The printing position returns to the standard
position by operating with the power ON,
depending on the sensor state as follows.
2
When positioned between the standard position
and the bottom limit:
Rotate the vertical registration motor normally (CW)
to return the printing position to the standard.
2
When positioned between the standard position
and the top limit:
Rotate the vertical registration motor reversely (CCW)
to return the printing position to the standard.
