■ Shutter Control

● Overview
To prevent image failure and reduction in productivity caused by temperature rise at the edge,
this machine introduces the Shutter (to shield magnetic flux; nonmagnetic substance), so that
position of the Shutter is controlled according to the detected temperature of the edge.
● Execution timing
• When reaching the detection temperature of Sub Thermistor (THM2) and Shutter
Thermistor (THM3) to the Shutter operation temperature
• When printing is completed
● Control description
By rotating the Shutter Motor (M15) for the specified amount, the Shutter is set in the
specified position. There are cut-offs on the circumference of the Shutter Drive Gear (front)
which is engaged with the Shutter. Detection of this cut-offs by the Shutter HP Sensor (PS53)
determines whether the Shutter is set in the specified position.
