Scanning Takes a Long Time
❏

“Selecting the Scan Resolution” on page 32 for instructions.

Computers with USB 2.0 (high speed) ports can transfer data faster than those with
USB 1.1 ports. Therefore, the scanning time may be shorter if you use a computer with
a USB 2.0 port. If you are using a USB 2.0 port with your scanner, make sure it meets
the system requirements. See “System Requirements” on page 142 for details.
