Scanning
If you want to scan documents using other software, you will need to use TWAIN-compliant software, such as Adobe PhotoDeluxe or Adobe Photoshop. The first
time you scan with your printer, select it as your TWAIN source in your application.
The basic scanning process involves a number of steps:
1. Load the document(s) face up with top edge in first into the ADF.
OR
Place a single document face down on the document glass.
For details about loading a document, see "Loading an Original Document" .
2. Open an application, such as PhotoDeluxe or Photoshop.
3. Open the TWAIN window and set the scan options.
4. Scan and save your scanned image.
NOTE: You need to follow the program's instructions for acquiring an image. Refer to the User's Guide of the application.
