Wait until the device reaches the READY state. • Check the software Make sure the software is properly installed. Scan takes too long • Check the settings ◦ If you set the resolution too high, the scan job takes longer and results in larger files. To obtain good results when scanning or copying, do not use a resolution that is higher than needed. You can lower the resolution to scan more quickly. ◦ If you acquire an image through TWAIN, you can change the settings so that the original scans in black and white. See the onscreen Help for the TWAIN program for information. • Check the status of the device If you sent a print or copy job before you tried to scan, the scan starts if the scanner is not busy. However, the printing and scanning processes share memory, which means that the scan might be slower. 126 Maintain and troubleshoot
