220-1102 Question 705
Single answer4.4 Given a scenario, use common safety procedures.A technician is dispatched to service a laser printer in a warehouse office. The printer is producing a burning smell, and the area around it contains stacked paper boxes and a recently used cleaning solvent. Before opening the printer to inspect the issue, what should the technician do FIRST to follow proper safety procedures?
- A
Power off the printer, unplug it, and verify the area is free of flammable materials before servicing
- B
Open the printer immediately to locate the failing component before it overheats further
- C
Spray compressed air into the printer while it is still running to cool internal components
- D
Move the printer to a different desk while it remains powered on so production can continue
Show answer and explanation
Correct answer: A
Explanation
This question tests application of common safety procedures in a realistic support scenario. When a device emits a burning smell, the technician should first de-energize it and assess the area for hazards, especially combustible materials such as paper and cleaning solvents. This aligns with standard workplace and IT safety practices: identify hazards, remove power from potentially dangerous equipment, and control the environment before beginning service. For printers, technicians should also remember that internal components such as fusers can remain very hot after power-off, so allowing cooling time is part of safe servicing. These practices are consistent with common manufacturer service guidance and general occupational safety principles for electrical equipment.
- A. Correct.
Correct. The technician should first eliminate the immediate electrical and fire risk by powering off and unplugging the device, then ensuring the surrounding area is safe. A burning smell indicates a potential overheating or electrical fault. Because paper and solvent are combustible, checking for flammable materials is an essential first safety step before any internal inspection.
- B. Incorrect.
Incorrect. Opening the printer right away skips the most important initial safety actions: disconnecting power and controlling environmental hazards. A technician may feel pressure to diagnose quickly, but servicing energized equipment with signs of overheating increases the risk of electrical shock, burns, and ignition.
- C. Incorrect.
Incorrect. Compressed air is not an appropriate first response to a burning smell, especially while the device is still powered on. It does not address the possible electrical fault and could disturb hot particles or toner. The primary misconception is treating the symptom as a heat issue rather than recognizing the underlying safety hazard.
- D. Incorrect.
Incorrect. Moving powered equipment that may have an electrical or thermal fault is unsafe. It keeps the hazard energized and could worsen the problem or expose the technician and nearby staff to injury. Business continuity is secondary to safety when a device shows signs of possible overheating or fire risk.
