You might get toner all over your fingers.
what are the disadvantages of photocopying?
1) Photocopiers create ozone gas. 2) Toner dust can cause respiratory tract irritation. 3) When placed in a poorly ventilated area, carbon monoxide gas can be produced, a deadly colourless gas that can lead to headaches, nausea and fatigue. 4) Photocopying is much cheaper than printing, which is good for you but bad for the company who are now affected and not going to receive as much money.
