Within the Button Configuration window click the File, Scan, FTP or E-Mail icon on the left pane and then click in the right pane, which opens this dialog box.  

The items and parameters available in the window are explained as follows:  

Keep the same image quality level for all modes  

Ticking this check box will unify the quality level for all scan modes, thus saving you the trouble of adjusting the quality level individually. If you prefer to manually adjust the image quality level for different modes, leave this check box cleared.  

Keep the same TIFF / PDF setting for all modes  

Ticking this check box will unify the TIFF / PDF setting for all scan modes, thus saving you the trouble of individually ticking or clearing the TIFF / PDF check box. If you prefer different settings for different scan modes, leave this check box cleared.  

Convert to PDF/A (Available for PDF format only)  

Tick this box to convert the PDF file format to PDF/A file format for long-term preservation of electronic documents.  

Image Quality  

For JPEG and TIFF-Compressed file formats, you can set the quality level individually for Color and Grayscale scan modes.  

You can adjust the quality value from 1 to 100. The higher the quality setting, the more detail is preserved, but a larger file size it would take. The smaller the image file, the lower quality the image has, but the less disk space it takes. The balance of image quality and file size needs to be determined according to your own needs.  

B/W images in TIFF-Compressed file format are always saved in Fax G4 format.  

If TIFF / PDF is chosen as the file format, you have three options to save the scanned images:  

•

Generate one TIFF / PDF file for all pages: save all the scanned images into one file; or  

•

Generate one TIFF / PDF file every X pages: save every X pages as a file. You can define the number of pages to be combined in a file.  

•

Generate one TIFF/ PDF file for scanned pages once a blank page is scanned: generate a new file each time a blank page is encountered. You can use blank pages to split the file.
