As shown in the above tables, the PCU cleaning unit contains 900K PM items and 1800K PM items. In order to make it clear which PM items have been maintained for the PCU cleaning unit inside the machine, the PM check sheet decal [A] is available. This decal should be pasted on the PCU cleaning unit as shown below.

  • The PM check sheet decal [A] is available as a service part P/No. M2053627.
  • From May 2015 production, this decal is attached to the PCU cleaning unit at the factory.

How to use the PM check sheet decal
  1. When the PCU cleaning unit is brand new (0KP), there are no check marks on the decal.
  2. When the 900KP PM is applied, check the 1st 900K column as shown.
  3. When the 1800KP PM is applied, check the 1st 1800K column as shown.

    • Keep making the check mark at every PM. For example, when the 6300KP PM is performed, the check marks should be as shown.

In the Case of TCRU/ORU Service

Using the PM check sheet decal, technicians can recognize which maintenance items should be performed for the PCU cleaning units, which are used alternatively as shown in above diagram.

The customers should not make marks on the decals, or this system will not work.

In the above example, at the customer’s site, there are two cleaning units; one is in the machine (‘In Use’) and one is standing by (‘Removed’). At the start of the machine’s life, neither of the units have any check marks on the decal.

The customer exchanges the units at 900k. The unit that was previously ‘in use’ is now ‘removed’, and vice versa. When the technician visits, the customer says that a unit needs servicing. The technician looks at the decal and sees no check marks. From that, the technician deduces that PM has not been done yet on this unit, so 900k PM must be performed. After servicing, the technician puts a check mark on the decal and tells the customer it can be used again.

The customer exchanges the units again at 1800k. The unit serviced by the technician, with one check mark on the decal, is now back in the machine ‘in use’. When the technician visits, the customer says that a unit needs servicing. The technician looks at the decal and sees no check marks (this unit has not been serviced yet). From that, the technician deduces that 900k PM must be performed on this unit. After servicing, the technician puts a check mark on the decal.

The customer exchanges the units again at 2700k. When the technician visits, the decal has one check mark (this is the cleaning unit that was serviced at 900 k). From that, the technician deduces that 1800k PM must be performed on this unit. After servicing, the technician puts the second check mark on the decal.

And so on.
