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.
