Difficulty: HardPrinter and Multifunction Device Issues

A technician is dispatched to troubleshoot a departmental color inkjet printer used for high-resolution graphics printing. Users report that outputted documents exhibit horizontal white streaks across images and missing color bands. A nozzle check diagnostic page confirms that several printhead nozzles are obstructed. The technician executes a standard software-initiated printhead cleaning cycle, but a subsequent test print shows only minimal improvement. According to standard troubleshooting methodology, which of the following actions should the technician perform NEXT to resolve the issue?

  1. Perform an intensive deep-cleaning cycle or manually clean the printhead nozzles with isopropyl alcoholAnswer
  2. B
    Adjust the printer driver settings to increase the fuser assembly temperature for better ink adhesion
  3. C
    Replace the printer motherboard and system power supply assembly
  4. D
    Reinstall the display adapter drivers on the workstation sending the print jobs

Answer

Perform an intensive deep-cleaning cycle or manually clean the printhead nozzles with isopropyl alcohol.
The correct answer emphasizes continuing with progressive printhead maintenance. Inkjet printhead nozzles can become severely clogged with dried ink. When a standard cleaning cycle yields partial improvement, running an enhanced deep-cleaning cycle or manually cleaning the printhead assembly using isopropyl alcohol is the appropriate technical action before resorting to component replacement.

Step-by-Step Solution

1
Analyze the reported symptoms and diagnostic results
Identified physical ink blockage in inkjet printhead nozzles causing missing bands and streaks.
The nozzle check pattern confirmed clogged nozzles, establishing a clear root cause focused on printhead maintenance.
2
Evaluate the outcome of the initial corrective action
The initial automated soft cleaning cycle yielded slight improvement, proving that ink buildup is dissolving but requires further clearing.
Severe or dried ink clogs frequently require secondary or deep cleaning cycles to flush remaining debris from microscopic printhead orifices.
3
Determine the next least invasive and cost-effective resolution step
Select performing a deep-cleaning cycle or manually cleaning the printhead with isopropyl alcohol and lint-free materials.
Escalating maintenance to deep cleaning or manual cleaning directly targets the remaining obstruction without unnecessarily replacing expensive components.
