Zorluk: OrtaPrinter and Multifunction Device Issues

Users in an administrative department report that a high-volume multifunction device (MFD) frequently pulls multiple pages at once through the Automatic Document Feeder (ADF) during batch scanning, leading to paper jams and missing pages in digitized files. Single-page flatbed scanning functions normally without issue. Which of the following components is most likely worn and requires replacement to resolve this issue?

  1. ADF separation padCevap
  2. B
    Optical scanner carriage assembly
  3. C
    Duplexing assembly rollers
  4. D
    Registration roller assembly

Cevap

Replacing the ADF separation pad will resolve the multi-sheet feeding issue during document scanning.
The correct option is the ADF separation pad because it provides friction to ensure that only the top sheet of paper enters the ADF scan path. When worn down through high volume use, it allows multiple sheets to be drawn concurrently into the feeder.

Adım Adım Çözüm

1
Analyze the symptom and mechanical location of the failure.
The failure occurs specifically when feeding paper through the Automatic Document Feeder (ADF) during scanning, while flatbed scanning operates normally.
This isolates the issue strictly to the mechanical feeding components inside the ADF assembly.
2
Identify the function of ADF paper handling components.
The pickup/feed rollers pull paper into the tray, while the separation pad applies friction to ensure only one page enters the paper path at a time.
When the friction surface of the separation pad wears down over time, it fails to separate stacked pages, causing multi-page feeds and paper jams.
3
Select the appropriate replacement component.
Replacing the worn ADF separation pad (often included in an ADF maintenance kit) restores proper single-sheet feeding friction.
It directly targets the root cause without replacing unrelated printing or optical assemblies.
