Platen Roller Pressure Release
The platen release motor [A] gives half a turn to the platen release cam [B] to apply
or release the platen roller [C] pressure. As the motor turns, the actuator on the
gear interrupts the platen release sensor [D]. When the pressure is released, the
actuator interrupts the sensor.
NOTE: When installing the gear with the actuator, remember that the setting
position depends on the platen release cam position. For details, refer to
the Replacement and Adjustment section.
Just before master making, the platen release motor starts turning until the sensor
is inactive; this indicates that the platen pressure is now applied to prepare for
master making.
When master making is complete, the motor turns again until the sensor is
activated, releasing the platen pressure. This allows the user to remove a jammed
master. Also, in standby mode, there is no pressure between platen roller and
thermal head, so that the user can take out the master. Also, this makes the life of
the thermal head longer, and prevents the platen roller from being deformed.
