Probably everyone who deals with printing devices repair of toner cartridge refilling sooner or later begins to wonder: 'is toner hazardous for me?'
Laser printers, copiers and toner itself cannot be positively defined as very harmful or absolutely safe. Like many Home Appliances, they have their maintenance rules to know and observe. Not taking precautions may have an unfortunate effect.
As far as copiers are concerned, you should consider this: image drum assembly heats up to 200 degrees Celsius and the coolers blow out gaseous waste products, dust and even toner (in the event that the device has poor technical condition or the cartridge is faulty).
Such temperature combined with water vapor derived from paper releases volatile organic reagents, which are contained in toner and paper. It is those reagents that are blown out from printer or copier. Some of them, like benzene or styrole, are considered to be very hazardous and classified as cancer-causing. This fact if often abused by tabloids to make up another sensational article. However, actual figures or comparison strength of the reagent are never mentioned. For instance, from those articles you'll never know that an average printer working continuously for an hour exhausts about 10 time less benzene than one smoked cigarette.
Ozone emission, once a hot topic, doe not appear on the agenda anymore. The reason is strict modern standards for printing equipments - Ã
