The mode is detected under the following conditions
2A mode
When the B mode sensor (PS4) is photointerrupted, the A / C mode sensor (PS3) detects the edge of
photointerrupting
f
photopasing.
*With the power ON, the A mode is determined when the B mode sensor is in the photointerrupting state
and the A/C mode sensor is in the photopassing state. If not in the A mode with the power ON, the
master clump opening / closing lever rotates to the B mode and stops. When the lever stops at the
B mode, the drum rotates with the drum rotation switch and returns to the A mode at the stop position.
2B mode
When the A/C mode sensor is photointerrupted, the B mode sensor detects the edge of photointerrupting /
/photopassing or photopassing - photointerrupting.
2C mode
When the B mode sensor is photopassing, the A/C mode sensor detects the edge of photointerrupting
f
photopassing.
