Hi rtman,
Thank you for using the Xerox forum.
I would suggest that you review the following site for the detailed scan to file documentation, as well as many other helpful tips and solutions.
WorkCentre 7830/7835/7845/7855 Support
I found the following in this linked user guide on page 169 which indicates that a custom file name can include the UserID
Setting Scanned Image File Naming Conventions
1. In CentreWare Internet Services, click
Properties > Services.
2. Click
Workflow Scanning > Custom File Naming.
3. Under File Naming, select one of the following:
-Auto: Type a prefix for the scanned image file name.
-Custom Naming: Under Display, select the elements you want to use to build the file name. As
you select display elements, they appear in the Position field. The display elements are:
•Date
•Time
•Job ID
•User ID
•Custom Text: Type any custom text you that want to appear in the file name. For
example, select the first Custom Text field and type an underscore ( _ ). The underscore
displays in the Position field. You can include up to four Custom Text strings in the file
name.
•Position: Click an element in the Position field. Use the Up and Down Arrow buttons to
move the element into the correct position for the file name. The file name generated uses
all the elements in the Position field, in order, from top to bottom.
−Advanced: Type a string using variables to create the file name. For details, see the Help in
CentreWare Internet Services.
4. Click Apply to save the new settings or Undo to retain the previous settings.
