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.
Vertical colored stripes appear on the printed page
Dust can build up on the scanning strip and cause artifacts in scanned images. Clean the scanning
strip (which is to the left of the scanner glass) with a soft, lint-free cloth that has been sprayed with a
mild glass cleaner.
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.
