Explanation
The duplex assembly in a laser printer is the component specifically designed to flip or re-route the paper so that the second side can be printed.
Common mistakes.
- A. The paper registration assembly aligns the paper and controls its timing as it enters the print path; it does not flip the paper.
- B. The paper pickup assembly draws paper from the input tray at the start of the print cycle; it has no role in re-routing printed pages.
- D. The image transfer belt transfers toner from the photosensitive drum onto the paper; it is part of the imaging process, not the paper handling path.
