Problem : My computer keeps giving me out of hard drive space error messages.
The minimum requirement of free hard drive space is for the installation of the scanner driver and basic, low
resolution, scanning. High resolution scans result in files that can be over 1 gigabyte in size. Free up some space
on your hard drive for the software to be able to save the scanned images.
Problem : The paper jams the ADF.
Open the ADF cover, pull out the jammed paper carefully, close the ADF cover. To reduce the number of paper
jams, smooth and straighten the paper before scanning, and adjust the guides to the paper size. Paper fed into
the ADF at an angle can cause the feed mechanism to jam. If paper jams are occurring more frequently, try
cleaning the roller with a soft cloth dampened with Isopropyl rubbing alcohol. Excessive dust on the roller can
make it appear worn and will cause issues feeding paper. See
Cleaning Inside the Automatic Document Feeder on
page 40 for cleaning instructions.
Problem : The ADF won’t feed pages properly.
A dirty or worn roller can cause documents to feed in skewed at an angle, or multiple pages to feed at the same
time. First, try cleaning the rollers as described in
Cleaning Inside the Automatic Document Feeder on page 40. If
the problem persists, the separation and/or feed rollers may need to be replaced. Please see Replacing the ADF
Roller on page 43 and Troubleshooting on page 48.
Problem: Why does my scanned image always come out too dark?
Adjust the screen settings to sRGB, and then adjust the brightness settings on the screen from application
software.
Problem: When I choose optical resolution to be 600 dpi, the "auto crop" and "deskew" functions will be disabled.
Since performing auto crop and deskew consumes a great deal of system memory, it is suggested to choose your
optical resolution to be smaller than 600 dpi to prevent an error message.
Problem : If the USB cable is disconnected during a scan, the scanner does not reconnect when the USB cable is
plugged back in.
Unplug the power cable from the scanner, and then plug it back in.
If the scanner does not reconnect:
1. Unplug the power cable from the scanner.
2. Restart your computer.
3. After the restart is complete, plug the power cable back in.
Problem : The scanner reports a Double Feed error when there is only one page in the scanner.
Try cleaning the double feed detection sensor. Dust on the sensor may prevent the sensor from working properly.
