FB ORIGINAL SCANNING MECHANISM

6. FB Original Scanning Mechanism
This scanning operation describes the following situations. One is in which the ABC (Auto Base Control)
is not performed. The other is when the START key is pressed within 60 seconds of placing the original
on the stage glass (START from FB original scanning operation 1), and when the START key is pressed
after 60 seconds.
If the START key is pressed after 60 seconds have elapsed, the lamp [B] illuminates, and the Flat bed
read pulse motor [A] activates in the feed direction. The Lamp carriage [C] moves to the shading
compensation position, and shading compensation is performed. (See the previous section for the case
in which line mode is selected with original scanning density set at "Auto", i.e. with ABC.)
It then moves a preset distance in the scanning direction (to the right) from the scanning start standby
position, and the write pulse motor activates. It then moves a further preset distance, switching ON the
read/write signal and initiating scan of the original. (The master making process starts at the same time.)
Once the master making for the size of the original is made, the read/write signal is switched OFF, and
scanning ends. (The master making process also ends at the same time.) The Flat bed read pulse
motor [A] moves the lamp carriage a further 3 mm in the scanning direction before stopping. The Lamp
[B] turns off, and the scanning operation is complete.
The Lamp carriage [C] then returns to the standby position. (Flat bed initialization operation)
