After long time usage, transportation mechanism would wear and tear, dust on sensor, magnetic head,
IC card contact will influence the performance of module, so it should be maintained on a constant basis.
Detail instruction is as following:
Use a cleaning card with alcohol to clean magnetic head by pulling and inserting in card reader for
several times.
Insert a cleaning card with alcohol and execute auto test IC card several times to clean IC card
contact.
Periodic maintenance: Maintaining the module (Magnetic head, IC contact, Mechanism) every
20,000 cycle is recommended.
（ One cycle: card in and card out ）
Different components’ maintenance is as following:
1) IC card contact maintenance: Insert an IC card with alcohol; execute auto test IC card
2) Magnetic head maintenance: Insert/pulling a cleaning card with repetition.
