MEMO:
The shutter can be opened/closed during printing. This does not intervene the printing.
The rate at which the shutter opens/closes is about 50mm / sec, and it takes about 1.15 seconds for the shutter to travel the maximum distance (between home position
and LTR position).
2. ON/OFF Control of the Edge Cooling Fan
As the fixing film edge temperature increases / decreases, the edge cooling fan is turned ON / OFF in order to adjust the temperature. The sub-thermistor 1 temper-
ature reading at the fixing film edge, paper size, paper type, the total number of paper passage are the factors that determines the temperature range at which the
edge cooling fan will be turned ON / OFF.
Below is a table showing the temperature rages at which the shutter fan will be turned ON.
