What should be used to pick up excess particles of toner when cleaning a laser printer?

Using a HEPA-capable vacuum is the best choice for picking up excess particles of toner when cleaning a laser printer. The reason this method is effective is that HEPA filters are designed to trap small particles, including fine toner dust. This capability ensures that the particles do not escape back into the air, which could pose health risks or further contaminate the printer.

Additionally, a HEPA-capable vacuum specifically reduces the risk of toner being released into the atmosphere during the cleaning process, ensuring a safer and more thorough cleaning of the printer environment. This approach follows best practices for cleaning printers and adhering to safety standards in environments where toner is frequently handled.

While other options like a soft brush, lint-free cloth, or compressed air can be useful for specific tasks, they may not effectively capture the fine toner particles without redistributing them or causing potential inhalation hazards. Therefore, the HEPA vacuum is the most effective and safe option for this cleaning task.
