Question

A laser printer has just had its toner cartridge removed and toner has leaked inside and out. The BEST method to remove spilled toner, both inside and outside of the printer, is which of the following?

Options

AESD vacuum
BMaintenance kit
CDamp towel
DCompressed air

Explanation

Toner is an ultrafine powder composed of plastic resin and carbon particles. The correct removal tool is an ESD (Electrostatic Discharge) vacuum, which is purpose-built for fine particles and uses filtration that prevents toner from passing back into the air. Compressed air (Option D) should never be used because it aerosolizes toner, creating an inhalation hazard and spreading contamination. A damp towel (Option C) causes toner to smear and can permanently stain surfaces. A maintenance kit (Option B) provides replacement wear parts (rollers, fuser, etc.) and is unrelated to cleanup. The ESD design also prevents static buildup that could damage internal printer components.
