5-2-3. Eject paper position
Fig. 5-5.
When the print button is pressed, the unit is put into this position. A ribbon bar code ring is read and the
type of ribbon is judged. At the same time, the paper supply tray size is judged, and the combination of
the ribbon and paper is judged.
The bar code ring can be read only when the system cam is at paper supply position. The bar code is read
using a bar code sensor by rotating the paper supply motor and turning the bar code ring via a paper
supply block and BC arm. If the platen is not at the home position, it is returned to the home position.
Next, the beginning of a yellow ribbon is detected. The supply paper motor is rotated and the paper is
conveyed to the chuck position. After that, while rotating the platen, paper is chucked. At this time, the
tray motor cam is set to the paper supply position, the paper supply arm is lifted, and the paper is pressed
against the pickup roller. At the same time, the separation roller is pressed against the paper supply roller
via a TM link for supplying paper. This separation method is used.
The paper supply FG sensor is counted from when the paper passes through the paper edge sensor, and
the timing of platen rotation start is measured.
When the platen is rotated about 55˚, the paper is chucked perfectly.( Actually, the chuck is closed
gradually.) At this time, the paper conveyance quantity by the paper supply roller is little much than the
paper conveyance quantity by the platen.
Next, when the platen is rotated about 120˚, the paper jamming sensor condition is examined. If the paper
is not reached, it is judged chuck miss and printing operation is stopped. In this case, open the lid for
jamming and take out the paper.
If the chuck is correctly performed, the print start position of paper is detected.

The paper supply tray becomes deep because this model corresponds to 200 images. Therefore, paper
setting is little difficult. Specially, if the paper is set with it’s folded, paper is not supplied. For the
symptom of this condition, confirm the paper condition in the paper supply tray.
.
When paper supply miss occurs, the paper supply arm may be lowered once to perform the paper
supply operation again (maximum two times). This is not a trouble.
.
After paper is supplied, the paper supply motor is reversely rotated a little in order to return the paper in
the paper supply tray. This is not a trouble.
