Answer: Use a numbered, non-sensitive proof stack to verify the feeder’s order, side handling and final file. A scan preview is an intermediate step; reopen the saved result.

Why the distinction matters
A feeder can scan one or both sides, and the application can reorder, omit blank pages or save multiple files. These settings interact with loading direction. A missing reverse side can be invisible if you only count sheets rather than expected page images. Start with the exact model’s supported document types and loading instructions.
A practical sequence
- Create a small proof stack with numbered fronts and backs and clear top arrows.
- Record the feeder and application settings, including blank-page removal.
- Scan through the documented loading route.
- Reopen the saved file and verify sequence, both sides, orientation and file count.
Decision record
| Check | What it means | What to verify |
|---|---|---|
| Physical sheets | Items loaded | Not the same as page images |
| Expected pages | Fronts and required backs | Basis for count check |
| Saved output | PDFs or image files | Verify after saving |
Worked example
Five hypothetical sheets with content on both sides require ten page images. A five-page result may indicate simplex acquisition, missing reverses or a file split. It does not become a complete scan merely because all five physical sheets passed through the feeder.
Verify the result
Repeat the proof after changing applications or duplex settings. Check that blank-page removal does not drop faint content needed by the task. Handle mixed sizes or fragile originals only as the manual permits.

Question and answer
Does a duplex printer necessarily have duplex scanning? No. Printing and scanning mechanisms are separate features. Verify the feeder’s documented side handling.
