ADF Scan Line
[B]
54mm
Two square black marks [A] and [B] (2 x 2 mm) are used to move the scanner
to the exact scan start position. At the start of scanning, the scanner moves
from the scanner home position, and looks for the appropriate mark, which
depends on the scanning mode (book or ADF). The machine uses the black
mark to move to the exact scan start position, which is nearby.
•

Book Scanner

When the machine detects the right edge of the black mark [A], it moves
another 4 mm to the scan start position.
•

ADF

When the machine detects the right edge of the black mark [B], it moves
another 54 mm to the scan start position.
If the black mark cannot be found, scanning continues, but error code 1-09 is
generated and stored in the error code memory area.
