• If scanning becomes slower after scanning continuously with the ADF for a long time, the scanner may

damaged. Let the scanner rest with the power on for 30 minutes, then try scanning again.
• If you are running virus protection or other security software, exclude the TWAIN.log files from
monitoring or set the TWAIN.log file as read only. See your virus protection or security software

• Computers with USB 3.0 (SuperSpeed) or USB 2.0 (Hi-Speed) ports can scan faster than those with
USB 1.1 ports. If you are using a USB 3.0 or 2.0 port with the scanner, make sure it meets the system
requirements.
