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 off.
Scanning Takes a Long Time
❏ The scanning speed may slow down depending on the scanning conditions, such as high resolution, image
adjustment features, file format, and so on.
❏ 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 software, exclude the TWAIN.log file from monitoring, or set the TWAIN.log as a read-
only file. For more information on your security software's functions, see the help and so on supplied with the
software. The TWAIN.log file is saved in the following locations.
