Automatic Thickness Adjustment Control (ATAC) key
For both thin and thick media, the Paper Ready LED lights up when the media is inserted into the original's insertion slot and correctly positioned. The media
can then be moved into the start-scan position by pressing the Paper Forward Key or through automatic loading. The Paper Ready LED will blink during
scanning.

What it means....
Paper Forward and Paper Reverse Keys
The Paper Forward Key moves the drawing into the start-scan position for manual loading (see section on
Loading).
If Auto-Load is set, loading will occur automatically (without pressing the key) when the original enters the
insertion slot.
Pressing the Paper Forward Key during scanning will stop the scanning process and feed the original through the
scanner while the key is held down.
The Paper Reverse Key stops the current scanning process and reverses the original. The original will be fed
backwards through the scanner while the key is held down.
When the scanner is in Automatic Thickness Adjustment Control (ATAC) mode the paper forward and paper
reverse keys become "pressure-platen up" and "pressure-platen Down" keys (see below).
Paper Ready LED Green - Ready for Normal media
The Paper Ready LED lights green when normal thin media is positioned correctly in the insertion slot and stays
green when the media is moved to the start-scan position.
From there, scanning can be controlled from the computer.
