Epson Perfection 640U Series Boletim de apoio ao produto - Página 4

Limitations of new driver:

• This driver does not support "Fast User Switching" in OS 10.3. This feature must be

turned off before using Epson Scan.

• You may receive an error "Epson Scan cannot be started" when trying to scan from

a Perfection 2450 that is connected to a USB 2.0 supported port. To avoid this error,

use a Firewire connection or a USB 1.1 only supported port.

• Not all the scanner models on this list support Color Restoration and Dust Removal

so these settings may be unavailable in Epson Scan.

• If experiencing unstable operation when scanning from a Perfection 1250 or 1260

scanner, restart your system.

• If the computer goes into "sleep mode" and this setting was enabled in the Apple

Menu and you try to switch to a different mode after doing a preview scan in

Photoshop, the Epson Scan driver will freeze. This does not happen if the computer

goes into "sleep mode" after screen saver has started. To avoid lock-ups, change

the scanning mode before the computer goes into "sleep mode" or re-launch Epson

Scan after the computer wakes up and then change modes.

• After scanning with the Perfection 1250, if you then close Epson Scan and

disconnect the USB cable, a scanner model selection dialog box may appear on the

screen. Click "No" and the box closes. You can scan normally afterwards.
