Scanning Speed Slows Down when Scanning Continuously
When scanning continuously using the ADF, scanning slows down to prevent the scanner mechanism from
overheating and being damaged. However, you can continue scanning.
To regain normal scanning speed, leave the scanner idle for at least 30 minutes. Scanning speed does not recover
even if the power is
o.
Scanning Takes a Long Time
When the resolution is high, scanning may take some time.
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 USB 2.0 port with the scanner, make sure it meets the system requirements.
When using security soware, exclude the TWAIN.log le from monitoring, or set the TWAIN.log as a read-
only le. For more information on your security soware’s functions, see the help and so on supplied with the
soware. e TWAIN.log le is saved in the following locations.
