2.2.2 Paper feed section
A unique paper feed is being composed, to carry out the high precision paper feed of the roll
paper and cut sheet by friction feed in this machine.
Figure 2-9. Paper feed department 1/2
paper feed department is composed of Pressure/subordinate movement roller assembly that
makes the direction to the PF roller (One structure), the traverse plane and was attached to
the CR guide rail back.
Using the DC servo-motor for the PF motor to feedback control on the basis of the output
pulse of the PF encoder. High printing precision is being maintained by this control.
The drive to the PF roller is notified through the PF timing belt, slowing-down pulley from
the PF motor.

The suction fan (x3) is installed in the reverse side of paper guide L2. Delimiting the
column direction space of the paper guide L2 reverse side in 3 rooms 1 fan is installed in
each room each. By beginning to inhale air in the printer package rear from the plural punch
hole on paper guide L2 of the paper path back adsorbing the paper to paper guide L1, L2
face I am intending the stable run (the buoy inhibition) of the paper. The suction fan
controls the wind quantity to 3 stages by the firmware control (full open / half open / shut)
on the basis of the printer action condition (at the time of the paper setting or the printing
