2.1.5 Paper Loading Mechanism (ASF Unit)
The Paper loading mechanism is positioned at the printer rear. The Paper loading
mechanism loads paper at the ASF unit and feeds paper to the PF roller.

Purpose
1.
When the specification 150 sheets of plain paper have been set, the customer
can generally check whether 150 pages are loaded from the thickness of the
ASF marking. However, it can be assumed that some customers might try to
force more than 150 sheets in. The ASF guide is shaped like a key so that no
more than 150 sheets can be placed into it so as to prevent paper feeding
problems. The result is that this key shape encourages the customer to remove
the excess number of sheets and to place them back into the hopper.
2.
Another purpose of the ASF support guide is that when the paper back lever
snaps back into place during paper feeding, the paper back lever also brings
the key-shaped ASF support guide back to prevent multiple sheets of paper
from being fed at once, thus improving the reliability of paper feeding.
This ASF unit was designed newly for this product and consists of LD roller, Pad
holder (Paper return plate), ASF Frame, Hopper, and so on.
For the major feature of this ASF unit, ASF HP sensor is not used and the single LD
roller is built in the ASF unit.
Drive sent from the PF motor is always transmitted to the ASF unit side. But, the
Change lever and the Clutch mechanism switch ON/OFF the PF motor drive to the LD
roller with the motor rotational direction.
