SCANNING AND CONFIGURING
30 SCANNING GUIDE
To select a JPEG file size:
1. Select JPG as the page format.
2. Right-click on the JPG icon.
3. Choose the file size/image quality option for your scanned images.
Minimize Size—smallest file size, lowest image quality.
Normal—medium file size, some loss of image quality.
Maximize Quality—largest file size, minimal loss of image quality.
Your selection pertains only to the button currently selected on the OneTouch Properties window. Other
buttons that have JPG selected as the file format are not affected, so you can set the JPG file size/image
quality independently for each button.
4. Click OK or Apply on the OneTouch Properties window.
Right-click on the PDF format icon to change the image quality or select the option to make the scanned PDF file
PDF-A compliant.
GIF—the *.gif (graphics interchange format) format is generally used when putting images on a website or server,
as image compression can reduce the file size by approximately 95% when compared to a BMP file of the same
image. Company logos and small pictures on a webpage are often GIF images. The GIF compression, and limited
color range, can result in the medium and large images looking grainy or pixilated.
PNG—the *.png (portable network graphics) format is another common image format for website graphics. Like
GIF, the PNG compression greatly reduces the file size when compared to a BMP file of the same image. However,
the PNG compression is different from GIF compression in that PNG images look better when scaled. Therefore,
PNG is often used in place of GIF for company logos with a lot of detail, clickable buttons, medium sized pictures,
and so on.
TIFF—the *.tif (tagged image file format) format is another image type that is often used for photo editing. When
scanning in color, it produces a file of similar quality and size to a BMP file. However, when scanning in Black &
White, the TIF compression produces the smallest file size of all the image types without losing image quality. TIFF
also supports multi-page image files.
JPG—the *.jpg (joint photographic experts group) format is a common image format for transferring pictures
electronically, such as posting to a website or sending via email, as JPG image files are smaller than BMP and TIFF
files. You can change the level of compression for the picture file to have better quality or a smaller file size.
PDF—the *.pdf (portable document format) image format is often used to create images of text pages. The image
compression of PDF files creates relatively small file sizes when scanning multiple page files in color. While the
TIFF image format also supports multiple page files, when scanning in color the TIFF files are often too large to be
transferred electronically. The PDF file format is often used for posting multiple page files to websites, sending via
email, and permanent storage. As with the JPG file format, you can change the PDF quality to reduce the file size
or improve the image quality.

, or other PDF viewer software, must be installed on your computer for you to view PDF files.
Using PDF-A when scanning as PDF, means the files are compliant with the ISO-19005-1 standard for permanent
archival of electronic documents. More information about this standard can be found at www.pdfa.org.
