4. MECHANICAL OUTLINE
4-1 Transmission Mechanism
When, in Fig. 4-1, the document is inserted, the first sensor detects the document and the transmission motor
starts to rotate.
Subsequently, the automatic document feed roller rotates and the document is fed to the position of the
platen roller (start position of scanning document) and is stopped.
The automatic document feed roller also works for the separation of the document when multiple documents
are inserted.
When [START] or [COPY] button is pressed here, the transmission motor rotates again and the document is
fed forward scanning by CIS.
The 2nd sensor works for detecting the separation of the document and controls paper feeding for stop
position.
4-2 Reception Mechanism
As shown in Fig. 4-1, the recording paper is pressed by the platen roller and the thermal head. The platen
roller is rotated by the reception motor and feeds the recording paper forward.
When printing is finished, the recording paper is fed to the cutting position and it's cut.
There are two sensors for the recording paper, one is for detecting the recording paper itself and the other is
detecting its jamming. It is noted that it will be a cause of recording paper jam when the recording paper is
not inserted straight or the roll is not tightened.
