Revision history
After publication of this service manual, the parts and mechanism may be subject to change for
improvement of their performance.
Therefore, the descriptions given in this service manual may not coincide with the actual machine.
When any change has been made to the descriptions in the service manual, a revised version will be
issued with a revision mark added as required.
Revision mark:
• To indicate clearly a section revised, is shown at the left margin of the revised section.
The number inside represents the number of times the revision has been made.
• To indicate clearly a page that contains the revision, is shown near the page number of the
corresponding page.
The number inside represents the number of times the revision has been made.
NOTE
Revision marks shown in a page are restricted only to the latest ones with the old ones deleted.
• When a page revised in Ver. 2.0 has been changed in Ver. 3.0:
The revision marks for Ver. 3.0 only are shown with those for Ver. 2.0 deleted.
• When a page revised in Ver. 2.0 has not been changed in Ver. 3.0:
The revision marks for Ver. 2.0 are left as they are.
