Ricoh2035e

Since you said a AF2035e. You must be using SMB scanning. You should be able to set the default file type under the send setting in the user tools---> scanner settings--->send settings. I believe the name of the setting your looking for is File Type Priority. Change it to the file type you prefer. Hope that helps.

I might have been wrong on the model.
It believe it is actually a 2035 using scan router pro.
Are you still able to set the scan file type default? Is is in scanrouter admin?

Yes you can set the file type to default to pdf with SR.

With Scanrouter you have to create a duplicated destination button with the file type changed. That way when the customer walks up to the MFP, he/she can select the file type based on the button you created. EX: one button named JDoe PDF-that scans to JDoe's My Docs. Create another button named JDoe TIFF going to same destinantion. But depending on the button pressed, you get the desired file type output.
Hope the helps,
