Chapter 5 CLEANING THE UNIT
1. Cleaning Each Section
The adherence of paper dust and printing ink on the rubber rolls and paper feed rings may cause
problems such as paper feed errors and folding misalignment. Adherence of paper dust near sensors
will also cause misdetection. Clean the machine once a week. We recommend that you use a com-
mercially-available air duster for office equipment to clean sensors.
● Prior to cleaning, be sure to disconnect the power cord from the outlet.
● After cleaning, make sure that the areas that were cleaned are completely dry before
resuming paper folding operations.
Do not use flammable sprays or solvent inside or near the unit (e.g.
when cleaning the unit).
Such flammable gas may ignite and cause a fire or combustion.
Take precautions against fire and ensure ventilation when using alcohol, and store the
alcohol in a safe place after use. Also note that use of other solvents can damage the
rubber rollers and resin inside the unit, resulting in malfunctions.
