Flatbed Initialization
Initialization is performed in the following situations to place the flatbed in standby mode:
•
When the power is switched on
•
When “All reset” is performed
Initialization operation
The FB/AF HP sensor is checked, and if it is OFF (open), the FB read pulse motor is activated in the
return direction until the light path is blocked, to move the lamp carriage to the left in the photograph.
Once the FB/AF HP sensor turns ON (blocked), it is moved a further set distance before the operation
ends (this is the “standby position”).
The detection plate on the FB/AF HP sensor is attached to the lamp carriage.
No movement is made if the FB/AF HP sensor is ON from the start.
The flatbed is moved to the shading position after moving to the standby position. Then, the lamp
illuminates, and peak detection is performed as part of the shading compensation operation. The lamp
finally turns off, and the flatbed is returned to the standby position.
