Purging mechanism
The purge mechanism is driven by the paper feed motor located at the left side of the main chassis.
As described in Subsection 4.2.2.1, the motor rotation is transmitted to the ASF/purge idle gear at
the right side of the main chassis. Engaged with the ASF/purge idle gear, the ASF-purge switching
gear 23 works as a clutch gear.
When the carriage travels from the left to right to reach the purge position, the tab provided on the
back of the carriage pushes the purge lever on the main chassis to the right (see the illustration
below). Accordingly, the ASF-purge switching gear 23 (which was shifted to the left by the purge
lever) will move to the right by the switching gear spring so as to become disengaged from the
gear 25 and engaged with the purge bevel gear A. (See the illustration given on the next page.)
This engagement will transmit the motor rotation to the purge bevel gear B on the purge unit. This
way, when the carriage is in the purge position, the motor rotation is transmitted to the purge unit.
On the contrary, if the carriage travels from the purge position to the left, the tab on the back of the
carriage releases the purge lever which will be pulled back to the left. The ASF-purge switching
gear 23 will be disengaged from the purge bevel gear A.
