Setting PDF File Saving Options
When saving scanned images as PDF (*.pdf) files, set the compression and OCR object language saving
options.
1 Click PDF File in the Options menu.
The PDF File Setting dialog box appears.
2 Make the following settings:
•Mode
Select the PDF file compression ratio.
High Compression
Files are saved with high compression. Image quality is degraded, but the file size is smaller.
Standard
Files are saved with standard compression.
Character Precedence
To prevent character legibility from degrading, only non-character areas are compressed when files
are saved.
Note
The Mode setting is only valid when the specified scanning mode is 256-level Gray or 24-bit Color, or
when a color document is detected with Auto Color Detection as the scanning mode. If the scanning
mode is a two-color mode such as Black and White, or Error Diffusion, the size of the file depends on
the size of the document.
