Dusting

Units that use paper or toner in operation, such as line printers and laser printers,
produce dust. The relation between dust-producing devices and device that should be
dust-free requires special consideration. For example, dust-free devices can be
installed near the air outlet, while the dust-producing devices can be near the air
intake.
