Paper Ready LED blinks Yellow – Scanner in ATAC mode
ATAC key

Paper Ready LED Yellow - Ready for Thick media
The Paper Ready LED lights yellow when the scanner is ready to scan thick media. The pressure-platen has
been lowered and the media is positioned correctly in the scanner.
The scanner goes automatically out of ATAC mode. The Paper Forward and Paper Reverse keys resume their
normal functionality so you can move the thick original forwards and backwards in the scanner.
Scanning can be controlled from the computer.
Paper Ready LED blinks – (green or yellow) – Media is being scanned
The Paper Ready LED blinks during scanning.
On completion of the scan, the Paper Ready LED will stop blinking. Scanning can then be repeated from the
computer or terminated by ejecting the media from the scanner.
The above behavior applies for both thin media scanning (green blinking) and thick media scanning (yellow
blinking).
Paper Ready LED Red – No Thick media detected
The paper ready indicator will light red if the pressure-platen is in a thick media setting (a raised pressure-platen)
but no media is detected in the scanner.
