Scanner Utility For Windows(R) XP/Windows Vista(R) Users: The Scanner Utility can be used to increase the maximum resolution of the scanner driver for resolutions greater than 1200dpi. If your machine includes a A3/Ledger Sized Flatbed Scanner or an ADF (automatic document feeder), then the Scanner Utility can also be used to configure the Windows(R) XP/Windows Vista(R) Scanner Driver to scan A3/Ledger Size paper. NOTE: - Scanning at resolutions greater than 1200dpi can create large file sizes and may cause problems with some scanning applications. - It is not possible to scan A3/Ledger Size documents from your machine unless your machine has a A3/Ledger Sized Flatbed Scanner.
