6. DESCRIPTION OF MODES
✽
1-Sided Original Mode
• When a multi-page document is being used, the copier detects the size of only the first
page of the document and runs for the subsequent pages based on that size detection.
• The mode is used when making copies of a document set consisting of pages of the
same size.

7-1. Document Take-Up Mechanism
Pick-Up Roller
Main Motor
Main Feed Roller
Document Empty Sensor
• The document is taken up as the Pick-Up Roller and Main Feed Roller turn.
• The Pick-Up Roller transports the document up to the Main Feed Roller, moving up and
down at all times during a document take-up sequence.
• The Pick-Up Roller and Main Feed Roller are turned through the Magnetic Clutch and by
gears driven by the Main Motor.
• The Document Empty Sensor is used to detect a document loaded on the Document
Guide.
• The leading edge of the document is determined by the Sprit Roller. when the document
gets over the Sprit Roller, it stops between Main feed Roller and Sprit Roller.
