Difficulty: Very hardPrinter and Multifunction Device Issues

A network technician receives an escalation ticket regarding a high-volume workgroup laser printer. Users report that printed pages contain smeared, unfused toner that wipes off easily when touched. Arrange the technician's troubleshooting and remediation steps in the correct chronological order according to the standard CompTIA troubleshooting methodology.

  1. 1Review user feedback, inspect the defective output pages, and examine the printer print queue and physical status.
  2. 2Formulate a hypothesis that the fuser assembly's heating element or pressure roller has failed and cannot achieve proper bonding temperature.
  3. 3Execute a built-in printer hardware diagnostic test and monitor fuser temperature readings to confirm the heating failure.
  4. 4Power down the device, allow the unit to cool, and swap out the faulty fuser module with a verified replacement unit.
  5. 5Power on the printer, run a multi-page diagnostic test page, and verify that toner adheres properly to the paper.
  6. 6Record the initial symptom, root cause analysis, part replacement details, and final outcome in the IT service desk ticketing system.

Answer

The correct sequence follows the six steps of the CompTIA troubleshooting methodology: (1) Review user feedback and inspect output pages; (2) Formulate a hypothesis regarding fuser heating failure; (3) Execute hardware diagnostic tests to confirm the heating failure; (4) Power down, cool, and replace the fuser module; (5) Power on and print test pages to verify full functionality; (6) Record all findings, root cause, and replacement details in the service desk ticketing system.
The correct order strictly adheres to CompTIA's 6-step troubleshooting methodology: 1. Identify the problem (inspecting pages and reviewing user reports), 2. Establish a theory of probable cause (attributing unfused toner to a fuser issue), 3. Test the theory (running diagnostic tests to confirm temperature failure), 4. Plan and implement the solution (powering off, cooling, and replacing the fuser), 5. Verify full system functionality (printing test pages), and 6. Document findings, actions, and outcomes (logging ticket details).

Step-by-Step Solution

1
Identify the problem
Gather symptoms and inspect printed output showing unfused toner.
Always begin by gathering details from the user and inspecting physical evidence to define the issue scope.
2
Establish a theory of probable cause
Deduce that the fuser assembly is not reaching melting temperature.
Unfused toner wiping off paper indicates the fuser heat/pressure mechanism is malfunctioning.
3
Test the theory to determine the cause
Run diagnostic tests to confirm the fuser unit failure.
Verification of the hypothesis is required before purchasing or performing physical part replacements.
4
Establish a plan of action and implement the solution
Safely replace the defective fuser assembly.
Implementation occurs after safety precautions (powering off and cooling down hot components) are met.
5
Verify full system functionality
Print test pages and verify proper toner bonding.
Testing ensures the issue is completely resolved before turning the system back over to users.
6
Document findings, actions, and outcomes
Log full details into the ticketing system.
Final documentation creates a historical reference for future technicians and closes out the ticket.
