If you are scanning to edit text, the optical character recognition (OCR) software requires more processing time than for non-OCR scans, which is normal. Wait for the item to scan.

NOTE: For the best OCR results, scanner compression should be set to the minimum compression level or disabled.

Scanning at a higher resolution than necessary increases scanning time and creates a larger file with no additional benefit. If you are scanning at a high resolution, set the resolution to a lower level to increase scanning speed.

The scan is completely black or completely white

The item might not be placed correctly in the document feeder. Make sure that the item you are trying to scan is placed face down.

Scanned images are not straight

Verify that the document feeder guides are centered on the scanner and set to an appropriate width for the original being scanned. Make sure the paper guides touch the edges of the original.

Vertical white stripes appear on the printed page

The destination printer might be out of toner or ink. Scan a different original to the same printer to see if the issue lies with the printer.

If the second scan has the same problem, try scanning to a different printer.

Scan files are too large

If the saved scan files are very large, try the following:

Verify the scan resolution setting:

200 dpi is sufficient for storing documents as images.

For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable text.

For Asian fonts and small fonts, 400 dpi is the recommended resolution.

Scanning at a higher resolution than necessary creates a larger file with no additional benefit.

Color scans create larger files than do black and white scans.

If you are scanning a large number of pages at one time, consider scanning fewer pages at a time to create more, smaller files.

Use the Kofax Virtual ReScan Software which shipped with your scanner to process the scanned data. Such software cleans up the image and compresses the data, which can result in a smaller file.
