Definition/Function:

Print shops and copy stations may contain many different types of printers or copy machines. Some ink or toner particles are released by any machine but the amount of pigmented particle released will vary significantly by local environmental conditions, the condition of the machine, and the work load. Paper, paper sizing, and paper brightener particles are released by the mechanical abrasion caused by the paper feed rollers.
