5-2-3. Paper Feed Position
Fig. 5 Paper feed position
Once the print button is pressed, the printer goes to the paper feed position to index the yellow ribbon.
If media are mounted after the power is turned on, the platen is initialized before a print operation is
started.
When indexing of the yellow ribbon is completed, the paper feed motor is activated to feed paper to the
chucking position. At this time, the tray motor cam is in the paper feed position to press-fit paper onto
the pickup roller with the paper feed lever up. In synchronization with this motion, the printer, using a
separation method, press-fits the separation roller onto the paper feed roller.
Once the direct chuck sensor confirms that paper has reached the chuck, the paper feed motor is stopped
to conduct a direct chuck operation.
When the chuck operation is completed, the printer starts rotating both platen motor and paper feed motor
in order to feed paper to the print start position. The paper fed by the paper feed roller is a little bit more
than that of the platen roller. If no paper reaches the chuck in the middle of operation, the paper jamming
sensor detects a chuck error and stops the print operation.
In such a case, remove the platen hatch at the bottom of the printer to eliminate paper.

Be sure to add protective paper at the bottom of the paper feeder tray. Without protective paper, print
paper may be scratched or a paper feed error may occur.
.
When refilling the paper feeder tray, put protective paper only at the bottom of the tray. If protective
paper is mixed with other paper in the tray, jamming may occur when the paper is printed.
.
In case of a paper feed error, the paper feed lever may be lowered once to continue feeding the paper
again (up to two times). This is not a failure.
.
The paper feed motor may rotate in reverse direction at the end of paper feeding or printing to return
paper to the paper feeder tray. This is not a failure.
