6.5 DESIGN THE PAPER OUTLET
6.5.1 Design the Shape of the Paper Outlet
When designing the shape of the paper outlet, note the followings.
Design the shape of the paper outlet of outer case so that stress is not applied to the thermal paper
to be ejected.
Design the paper outlet of the outer case and the platen holder so that the thermal paper eject angle
must be within of 60° to 90° as shown in Figure 6-4. However design the paper eject of outer case
so that thermal paper can be ejected without changing its eject direction. Do not change the paper
eject direction around the paper eject of printer mechanism. If changing the paper eject direction,
verify the performance with your actual device.
If using a paper winder to wind the thermal paper, allow the paper to eject naturally for at least 4mm
in length from the center of the platen. Design the outer case referring to Figure 6-6. Verify the
performance with your actual device. Otherwise, printing defects may occur or also the motor may
step out of the position.
