The Scanned Image of a Picture or Photo is Rough/Image Noise Appears
Check the following points
● Did you configure the settings in the scanner driver to scan in black & white mode? (page 184)
● Are the glass and rollers inside the ADF clean? (page 184)
If the problem persists, check the items in Before You Contact the Scanner Service Provider (page 190)
first, then contact the distributor/dealer where you purchased this product. Refer to the contact
information in the Contact List or the Contact for Inquiries section in Safety Precautions bundled with this
product and make an inquiry.
● Did you configure the settings in the scanner driver to scan in black & white mode?
Solution
Use a scanner driver to configure the scan settings that do not "binarize" (output in black and white), and
then perform a scan.
The scanned image may differ from the original image significantly if you simply "binarize" (output in
black & white) a picture or a photo.
● Are the glass and rollers inside the ADF clean?
Solution
Clean the dirty parts.
For details, refer to Daily Care (page 115).
