Scanner Settings

Use the following scanner settings to achieve the best results with CCH Scan.


Setting	Recommended	Notes
Resolution	300 dots per inch (dpi)	This setting provides a high-quality image without diminishing system performance.
Compression	CCITT Group 4 Fax or Fax Group 4	This setting maximizes performance while also managing the file size.
Page size	Letter or Legal Size	Documents that are not fed into the scanner correctly can create larger images that may cause errors. Forcing page size prevents this.
File format of file output from the scanner	TIF (not PDF)	TIF images are high quality and easier to troubleshoot than some other types of files.
Advanced settings Enhanced image Dithering Interpolated	Disabled	If enabled, these settings may cause the scanner to attempt to fill in missing pixels, which can blur text and negatively affect text recognition.
Image color	Black and white	Do not use the grayscale setting, which introduces additional pixels into the image that can negatively affect the accuracy of the data extraction.
Fill with Black setting	Disabled	This setting fills every blank space (such as a hole punch) with black, which can negatively affect recognition.

Note: If your scanner creates separate documents for each page when scanning, we suggest you scan documents into an intermediary folder. Then, you can move files to an Import folder. If you scan directly into an Import folder, CCH Scan processes each page separately and creates single-page PDF files in the Export folder.
