Scan Issue - Document Scans to very large PDF Size

My Cannon ImageCLASS was scanning documents to PDF format without an issue until recently. Now all documents open in Adobe Acrobat with very large page sizes. Does Scan have a magnify/zoom setting? Not sure what happened that is causing all scans to save
in such a large page format.

 

Scan Issue - Document Scans to very large PDF Size

I saw this issue about a year ago -- when I used Scan with an older MFC 8860DN with letter sized pages under Windows 10.

As I increased the dpi of the scan, the scanned pdf linear size increased in proportion.

The workaround I use is to print to pdf from the Adobe Acrobat Reader, with the "Fit to Page Size" button selected. With my printer output set to 8.5"x11", both the linear dimensions, and the file size in MB returns to sanity. The scanning is slow, and it
is a 2 step process, but it works.

 

Windows 10 Scan App - PDF File Sizes Too Large

Hi Teja,

There are several reasons why the scanned file as PDF gets too large. Here are the most common causes:

• Dot Per Inch (DPI) - Most scanners will use 300 DPI for scanning images, which is the minimum DPI for the images that were printed after scanning. However, 72 DPI should be already enough for a PDF that is for screen reading.
• Saving the document as colored - Use black and white instead of color when scanning images to lessen file size. Make sure that any color settings such as
  Color Depth are also decreased.

If the suggestions have been tried but the PDF file size is still too large, the next option is to check the PDF software that is performing the conversion itself.

Let us know if you were able to lessen the PDF file sizes using the suggestions above or if you need further assistance.
