Problem The scan takes too long Cause Solution CAUTION Do not try to pull the original from the ADF; you might damage the scanner or your original. See Jams in the ADF on page 195. The original is too small. The media size is incorrect. The resolution or color level is set too high. The software is set to scan in color. A print job or copy job was sent before you tried to scan. The minimum size that the flatbed scanner supports is 25 x 25 mm (1 x 1 inch). The minimum size that the ADF supports is 127 x 127 mm (5 x 5 inches). The original might be jammed. See Jams on page 177. In Scan settings, make sure that the input media size is large enough for the document that you are scanning. Change the resolution and color level settings to the correct settings for your job. The system default is color, which takes longer to scan even when scanning a monochrome original. If you acquire an image through TWAIN or WIA, you can change the settings so that the original scans in grayscale or black-and-white. See the all-in-one software Help for details. If someone sent a print job or copy job before you tried to scan, the scan will start if the scanner is not busy. However, because the all-in-one and scanner share memory, the scan might be slower.
