MECHANICAL OUTLINE
O. 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 also rotates and
the document is fed to the position of the platen roller and is stopped.
(the automatic document feed roller also works for the separation of the
document when multiple documents are inserted)
When the START or COPY button is pressed here, the transmission motor
rotates again and the document is fed forward.
@. 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 the printing is finished, the
recording paper is fed to the cutter until its 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 for 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 is not rolled tightly.
