Review the following information about resolving image quality problems.
The scanned images are not straight
Check the following to resolve the issue.
-
Verify that the paper 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.
-
Windows: Use the Straighten Content feature to straighten content that is skewed relative to the page dimensions in the source document. Use the Detect Size feature to deskew page images that might have become skewed during the scanning process.
The scanned image is fuzzy
Check the following to resolve the issue.
-
Check for any obstructions in the scanner paper path and make sure the paper guides are positioned appropriately. Try another scan.
-
Verify that the document is not fuzzy.
-
Dust can build up on the scanning strips inside the document feeder and cause low-quality scans. Clean the scanning strips with a soft, lint-free cloth that has been sprayed with a mild glass cleaner.
The scanned image is completely black or completely white
Check the following to resolve the issue.
-
The item might not be placed correctly in the input tray. Make sure that the item being scanned is placed face down in the input tray.
-
Windows: If scanning to a black and white image, make sure neither the black nor the white threshold is set to extreme. Setting the threshold to an extreme will result in an image that is all white or all black.
-
macOS: If scanning to a text image using the Image Capture application, set Image Correction to Manual and use the Threshold slider bar to adjust the threshold.
The bottom of the scanned image is cut off
By default, the scanning software can scan media that is up to 356 mm
long.
Verify that the page size selected in the scanning software (or the scan shortcut selected) will accommodate the length of the document being scanned.
The scanned image cannot be enlarged
The software might be setting the exposure for the entire scan area instead of for one small original. Select and drag the handles around the selection area until you see the image area you want to scan.
