to the inspection and

• The inspection and maintenance of the image reader is broken down into four

maintenance intervals:

- Half year maintenance

- One year maintenance

- Two years maintenance

- Three years maintenance

NOTE

The inspection and maintenance of the image reader should be carried out together with
the Fuji Service Manual FCR 5000MA plus, chapter Preventive Maintenance.

The correlation of the described inspection and maintenance work steps for the image
reader to the individual points in the Checklist for Inspection and Maintenance, SPB7-

420.832.01..., are indicated by the reference.

All other parts of the system are maintained on a yearly basis.

Example:

Cleaning the air filters

➪ Checkpoint Fuji 6.

• The complete sequence of inspection and maintenance work steps can be found on the

following pages.

• For the MAMMOMAT 3000 Nova, maintenance according to the appropriate SPB7-

230.101... instructions must be perf ormed.

• For other components of the system, maintenance according to product- accompanying

documentation must be performed.
