MECHANICAL OUTLINE
4-1. Transmission
When, in Fig. 4-1, the document is inserted, the first sensor detects the document and the motor starts to
rotate. Subsequently, the automatic document feed (ADF) 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] button is pressed here, the 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.
The GEARS and CAMS are positioned showing in Fig. 4-2 and the GEAR 3, 4 and 5 do not rotate.
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.
The GEARS and CAMS are positioned showing in Fig.4-3 and GEAR 3, 4, 7 and 8 do not rotate.
4-3. Copy Mechanism
When, in Fig.4-l, the document is inserted and [COPY] button is pressed, the transmission and reception
rollers rotate simultaneously.
The GEARS and CAMS are positioned showing in Fig.4-4 and GEAR 3 and 4 do not rotate
4-4. Cutting Mechanism
Paper cutting is performed right after receiving and copying has been done. The GEARS and CAMS are
positioned showing in Fig.4-5 and GEAR 7 and 8 do not rotate. The GEAR 5 rotate reversely in the middle of
cutting operation.
The cutting operation is finished by detecting a full rotation of GEAR 4 by cutter position switch.
