Zorluk: OrtaPrinter and Multifunction Device Issues

An IT technician is troubleshooting a departmental laser printer that is producing output with two distinct problems: printed text leaves faint repeat ghost images at regular vertical intervals down the page, and the toner smudges easily when handled immediately after printing. Which TWO of the following components are most likely responsible for these defects?

  1. Imaging drum unitCevap
  2. Fuser assemblyCevap
  3. C
    Transfer roller
  4. D
    Pickup roller

Cevap

The imaging drum unit and the fuser assembly are the two defective components requiring inspection or replacement.
Ghost images recurring at fixed intervals stem from a failing imaging drum or wiper blade, while smudging toner points directly to a malfunctioning fuser assembly that fails to apply adequate heat and pressure.

Adım Adım Çözüm

1
Analyze the ghosting symptom.
Identify that repeating ghost images at uniform vertical intervals indicate a defective imaging drum or cleaning blade failing to clear residual charge and toner.
The drum rotates continuously during printing; defective discharge lamps or worn drum coatings repeat image artifacts with every rotation.
2
Analyze the smudging symptom.
Identify that easily smudged toner indicates an issue with the fuser heating element or fuser rollers failing to melt toner into paper fibers.
Toner requires specific heat and pressure from the fuser assembly to bond permanently to media.
