Scan is not clear


Hi. The fuzzy might be the glass needing cleaning (both sides) and the grainy scans could be that the scan resolution has been accidentally changed.

Fuzzy scanned image from Epson Expression 10000XL scanner


Make sure that the item being scanned is lying flat against the scanner's glass. If the scanned image is still fuzzy after adjusting the object, clean the scanner glass with a lint-free cloth and some vinegar or ammonia-free window cleaner.

Xerox Documate 152 - Scan quality is now V.BAD!


I would go to Xerox.com and look up their knowledge base. Here is a copy of data from their site related to this problem:

Symptom: Scanned images have poor image quality, are fuzzy, unclear, or hard to read.
Cause: There are several things that can lead to poor image quality including the scan settings, dirt on the scanner, and driver problems. Solution: Note: If you scan as a PDF file and your scans look fuzzy when viewed in PaperPort, try right clicking on the file and selecting "Open" to open them in Adobe Reader. If they display fine in Adobe Reader then there is nothing wrong with the scans, it is simply that they are not being displayed well in PaperPort.

The following solutions can help resolve poor scan quality.

Solution 1 - Adjust the scan settings

Try increasing the resolution of your scan. 300 dpi to 400 dpi should be clear for most images
  • If you are scanning in Black and White, try Grayscale or Color. Some images will not display correctly in Black and White
  • You can also try adjusting the brightness and contrast
  • Note: For information on adjusting your scan settings, refer to the user guide for your scanner
Solution 2 - Clean and Calibrate the scanner

Note: Calibration only applies to sheetfed scanners.

Solution 3 - Reinstall the scanner driver Select a link below for instructions on reinstalling your scanner driver:

Scanned image appears to have an exposure problem


Are you using the software from HP? It sucks. Use the one provided my your operating system works great. Go your Control Panel, Printer and other Hardwares and click Scanners, make a shortcut to your task or start menu and Scan Away!!!!

Scans slides too dark.


maybe the slides are too dark, in other words, the pictures you took didn't have enough exposure therefore you it shows up dark.. You could always use photoshop or someother photo manipulation software to lighten the scan, same thing happens with my hp scanner with slide adapter, if it slides just show up dark, lightening it with software will help, unless it is unsaturated/shadows too dark, etc..

Hope this helps.

This has something to do the brightness chosen. In the manual mode, if you choose a dark output, the output will have tis area also; if you choose, lighter output, it will omit. In the auto scan mode, the scanner decides what is the best output.
