NOTE: For the best OCR results, scanner compression should be set to a low compression level or disabled. Resolution should be set to 300 ppi (dpi) for English and European languages and 400 ppi (dpi) for Chinese or Korean character recognition.

yScanning 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. In addition, the application used for scanning may support "deskew" to straighten the scanned images. Note that performance may be negatively affected but the results may be superior.

Vertical black stripes appear on the scanned image

There is dirt on the scanner glass. Clean the scanner glass.

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.

•Most scanning applications allow users to control the compression used for output files. Refer to the documentation for the scanning application for more information.
