2.1.4 Paper Feeding Mechanism

The paper feeding mechanism consists of paper feed motor (PF motor), PF roller, paper
eject roller, paper guide, and so on.

The paper feeding mechanism feeds paper loaded from ASF using the PF roller and
paper eject roller.

Figure 2-5. Paper Feeding Mechanism (Top View)

The following stepping motors are used to drive the paper feeding mechanism.

Table 2-4.

PF Motor Specifications

When DE (disengage) lever is at normal position, torque from the PF motor is sent to
the PF roller and paper eject roller as described below.

Stylus Photo 720 / Stylus Photo EX3 allows printing up to the last 3mm like Stylus
Photo 750 / Stylus Photo 1200. The star-wheel roller assembly has been shifted 5
degrees from directly on the top of the eject roller towards the paper feed roller. This
suppresses the tailing edge of the paper so that the old minimum margin of 14mm (ex.
for Stylus Photo 700 / Stylus Photo EX) has been reduced to only 3mm.
