Difficulty: MediumPrinter and Multifunction Device Issues

A graphic designer reports that full-color proof sheets printed on a dedicated desktop inkjet printer exhibit faint horizontal white streaks across images and slightly misaligned color edges. The ink tanks are confirmed to be full. Which TWO of the following maintenance procedures should the technician perform to resolve these print quality issues?

  1. Run a printhead nozzle cleaning utility to clear blocked ink channels.Answer
  2. Perform a printhead alignment calibration through the printer software.Answer
  3. C
    Replace the fuser assembly and transfer roller.
  4. D
    Assign a static APIPA address to the local printer spooler service.

Answer

The technician should run a printhead nozzle cleaning utility to clear blocked ink channels and perform a printhead alignment calibration through the printer software.
Horizontal streaks across inkjet prints are caused by clogged printhead nozzles preventing ink deposition, which is cleared by running a nozzle cleaning utility. Misaligned color edges occur when printhead alignment drifts out of tolerance, which is resolved by running a printhead alignment calibration.

Step-by-Step Solution

1
Analyze the observed print quality symptoms (horizontal streaks and misaligned color borders) relative to inkjet technology.
Identified clogged nozzles causing missing ink streaks and misaligned printheads causing registration errors.
Horizontal white lines on inkjet output indicate missing dots due to dried ink in the nozzles, while misaligned edges indicate printhead misalignment across passes.
2
Select the appropriate software maintenance utilities for inkjet printers.
Initiating a nozzle cleaning cycle clears dried ink obstruction, and running alignment calibration re-aligns the printhead nozzles.
Both procedures directly target the identified physical printhead defects using standard manufacturer maintenance tools.
