8-1-10-5 Paper Feeding
Paper feeding is performed by conveying the paper feed motor` s rotational power from the paper feed motor
gear through the paper feed reduction gear, paper feed gear, and paper fed roller.
Since the paper feed roller and paper hold roller are pressed together, paper advances to the top of the
paper feed frame assembly because of the friction between the rubber of the paper feed roller and the paper
hold roller.
As shown in Figure, Paper feeding mechanism consists of Rubber Roller Hold Roller Assy, Step Motor, Gear
Step M/T idle, Gear MF and Gear M/F Idle The paper feeding operation can be selected by controlling the
Step Motor. For detail explanations of paper feeding operation, refer to "SPECIFICAT10NS
for SMP-710/710N".
Paper feeding is made as follows; As Step Motor set turning by electric signal, Gear Rubber Roller comes
into turning, passing Gear Step M/T Idle for Shaft Roller is pressed to rubber Roller by Spring Roller, Paper is
feed by friction A min. Pitch is 1/144".
Under condition Step Motor stops, turning Gear MF to direction of arrow or to 1, he contrary, and can feed or
back feed as paper wants.
