4. Pressing the hopper
The hopper cam on the LD roller shaft presses the hopper and remaining paper on
the tray is moved away from the feeding position.
5. Moving the paper anti-slip tabs upward
The LD roller shaft rotates to actuate the lever on the shaft and move the paper
anti-slip tabs upward. The tabs prevent the paper from slipping into the paper
feeding section.
6. Transporting paper in the printer
Paper fed into the printer is transported by the PF roller.
7. Releasing the back end of paper
When the hopper actuating cam presses the hopper further in synchronization with
the rotation of the LD roller, left and right paper guides that regulate the paper
width are extended releasing the back end of paper.
