- People printing double-sided without duplex hardware
- Worth noticing
- A seven-page document has four fronts but only three backs; the guide explains how a blank page prevents the backs shifting onto the wrong sheets.
Field notes
The workflow starts with a two-sheet test on scrap paper; the user reports how the stack came through, and the wizard uses that result to set the backs' order and orientation. The guide calls out several failure modes, including curled sheets feeding together, and recommends batches of about 20 sheets so a jam affects less of the job. The page says the PDF stays in the browser, though the extracted homepage does not show a completed run.
