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.
● Are the glass and rollers inside the ADF clean?
Solution
Clean the dirty parts.
For details, refer to Daily Care (page 115).
● Is the resolution appropriate?
Solution
Specify a higher resolution in the scanner driver.
● Did you configure the settings in the scanner driver to scan in grayscale or color mode?
Solution
Configure the settings in the scanner driver to scan in black & white mode.
When you scan in grayscale or in color mode, the scanned image may not become sharp and clear.
● Is there any foreign matter (such as dust or paper dust) on the document?
Solution
Remove any foreign matter off the document.
Foreign matter may get on the glass that is inside the ADF, and cause the image to appear dirty.
