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 etc.) and form kind. Doing the shutter control with the
stepping control of the Shutter motor, after the home position (full open) is detected
with the shutter home sensor. The suction ability is controlled by shutter and shutter
motor duty.
