Was surprised with a color laser printer to call my very own (at work anyway) last week. Now that the beast is up and running, my boss practically has me running a color copy shop from my desk...
I just noticed the distinct and quite strong fragrance of printer toner as I walked in the door (after making the most recent delivery to the boss man), and couldn't help but think, "This can't be good for me."
One wonders... do Kinko's or Copy Max have a secret study hidden away somewhere at corporate headquarters about the health effects of large-volume laser toner fumes exposure on employee health? (Then again, maybe it's just the cold pills talking today...)
Since color pigments are probably made of heavy metal salts they must be harmful. Most print shops run a special ventilation system for that reason.
A simple air ioniser can be effective against laser toner fumes. I notice some printer toner powder all around the device here. I prefer dusting it off the desk every week than coughing it out of my lungs every day.
What you're smelling is most likely the ozone, all laser printers emit that to a certain degree. If it's a half decent machine, then it will have an air filter that keeps the toner particles from clouding the atmosphere.
