3. As you can see pictures, hopper is in the stand-by condition depending on
"coupling shaft limitation lever" position, and this continues keeping by the
"slowdown nail".
4. On the other hands, user can install paper(s) onto the hopper under the initial
hopper status, and the "paper return lever" prevents unexpected paper loading into
the printer internal.
NOTE: To make ASF activate, CR unit moves to left end of the CR shaft to push
the ASF trigger lever(ASF change lever), which is coupling in the clutch
gear system.
Step 2 : Loading Sequence
5. Once the printing data is input or load/eject switch is pressed down, the silence
cam will rotate to counterclockwise direction in Figure 2-16 to bring the hopper to
the hopper-state. In this sequence, when the top of the "slow down nail" reaches at
top of the red row in Figure 2-16, hopper has already been located in hopping
state, and a first paper has already been loaded to the printer internal.
6. Figure 2-17 shows the hopper condition when the top of "slow dawn nail" locates
at top of red row in Figure 2-16. At this time, any clatter noise will not be occurred
caused by the shape of silence cam.
6-1. Hopper condition:
Hopper has already been in hopper-state.
6-2. Paper return lever condition:
Paper return lever is in laid to insert a first paper to the printer internal.
6-3. LD roller has already been on the way of rotating to the forward direction:
Therefore, some degrees area of a top paper has been loaded to the printer
internal.
Please note that paper return lever is operated by the cam gear
located at backside of the silence cam. Refer to Step 5 for details.
