BJC-50 3.3.2 Operation Part 4: Technical Reference The purge section is driven by the paper feed motor. The paper feed motor drives the paper feed gear through the paper feed double gear. When the carriage moves to the right from the home position, the trigger gear rotates along with the paper feed gear, which rotates the pump gear and cylinder gear. At this time while the ink is stored in the cap, the cylinder gear rotates so as to move the piston shaft to the right. After that, the piston shaft is moved to the left so that the ink in the cap is absorbed into the waste ink absorber. The cap moves up and down as the pump arm moves along the pump gear cam.

3.3.2 Operation
The purge section is driven by the paper feed motor.
The paper feed motor drives the paper feed gear through the paper feed double gear.
When the carriage moves to the right from the home position, the trigger gear rotates
along with the paper feed gear, which rotates the pump gear and cylinder gear.
At
this time while the ink is stored in the cap, the cylinder gear rotates so as to move the
piston shaft to the right.
After that, the piston shaft is moved to the left so that the
ink in the cap is absorbed into the waste ink absorber.
The cap moves up and down as the pump arm moves along the pump gear cam.
