Scanning expectations / recommendations for Virtual Office CS

Alerts and notices

Engagement CS, FileCabinet CS, Workpapers CS and Fixed Assets CS provide the ability to scan documents, using your TWAIN-compliant scanner, to add documents directly into the applications.

When scanning into a locally-installed application, many factors can affect the performance of the scan job: temporary files, memory on the computer, DPI settings, color settings, and more. When scanning into any Terminal Server environment, including Virtual Office CS and SaaS, those factors become even more important, and bandwidth also becomes a factor.


This list contains commonly helpful tips but is not exhaustive.

  • Try using a different scanner driver. Many TWAIN-compliant scanners include different TWAIN and WIA drivers./li>
  • Download and install an updated TWAIN driver for your scanner, since updated drivers may contain performance enhancements. See your scanner documentation or the scanner manufacturer's website for more information.
  • Evaluate your bandwidth speed. When uploading the scanned images into the application in Virtual Office CS, you are uploading potentially large files through the Internet - you want to ensure that you have enough upload speed to handle the job efficiently.
  • Modify your scan settings:
    • Reduce your DPI (dots per inch) - many scanners default to 300 DPI or higher. To save file space and time, all CS Professional Suite applications except FileCabinet CS, automatically reduce the DPI to 100 DPI, the highest level that the human eye can differentiate.

      Note: If using Source Document Processing (OCR), you will need to use 400 DPI. Lowering your DPI to 100 DPI will reduce the time it takes to upload the file to Virtual Office CS but will not be sufficient for the OCR process.

    • Color vs. Black & White - Color scans are larger than black & white or grayscale scans. If you have no need for color in the documents you are scanning, changing your scanner settings to black & white or grayscale can greatly reduce the size and upload time of the files being scanned.


The following table gives a comparison on the size of a file if scanned with different color modes and DPI settings. These numbers are based on a 10 page 8.5" x 11" document. Different scanners may cause variations in file sizes. Larger sized documents will require a higher amount of bandwidth and will take longer to scan into applications.

Color Mode Black & White Black & White Color Color Grayscale >Grayscale
DPI settings 100 300 100 300 100 300
File Size 1.21 MB 10.97 MB 27.5 MB 247.5 MB 9.2 MB 82.82 MB
