Difficulty: HardSafety Procedures and Environmental Controls

An IT technician is dispatched to perform hardware maintenance on a commercial high-volume laser printer that recently experienced a major internal toner spill and high-voltage power fault. Which TWO of the following safety and environmental procedures must the technician implement to safely complete this repair?

  1. Allow the printer's fuser assembly to cool down fully prior to handling internal components to prevent severe thermal burns.Answer
  2. Use a specialized electrostatic-discharge (ESD) safe vacuum equipped with a fine particulate HEPA filter rather than a standard vacuum cleaner to clean toner dust.Answer
  3. C
    Attach an ESD wrist strap clip directly to an active AC power wall outlet's neutral slot to ground static buildup while cleaning sensitive circuit boards.
  4. D
    Incinerate the spent toner cartridges on-site in a high-temperature waste bin to neutralize chemical pigments before disposal.

Answer

The technician must allow the printer's fuser assembly to cool down completely before touch or removal to avoid thermal burn injuries, and use a dedicated ESD-safe toner vacuum with HEPA filtration to clean spilled toner particles safely.
Laser printer maintenance presents specific physical hazards: fuser units reach extreme temperatures requiring time to cool to prevent thermal burns, while spilled toner consists of ultrafine conductive particles that require specialized ESD-safe vacuums with HEPA filters to avoid airborne dispersion, static ignition, and hardware damage.

Step-by-Step Solution

1
Identify high-temperature hardware components before touching internal printer assemblies.
Recognized that the fuser unit maintains extreme thermal energy and requires cooling down time to ensure technician safety.
Prevent severe skin burns from components operating above 200°C.
2
Evaluate proper cleanup tools for microscopic toner powder.
Selected an ESD-safe vacuum featuring HEPA filters designed specifically for toner dust.
Standard vacuums create static electricity that can ignite toner dust clouds and blow fine toxic particulates back into the breathing environment.
3
Review proper disposal and ESD grounding safety protocols.
Rejected unsafe grounding practices to live AC lines and illegal incineration procedures for chemical waste.
Ensures adherence to CompTIA A+ environmental guidelines and personal electrical safety.
