2.1.1.12 Ink Valve Mechanism
The purpose of ink valve mechanism is to prevent ink leaking during re-
transport after the serve is completed. Stylus Pro5000 does not have the
waste ink sequence like Stylus Color 3000 had, instead, this ink valve
mechanism prevents leaking from the ink pack. Also, in case of Stylus Color
3000, when the waste ink sequence is performed, the program performs
initial ink charge automatically by turning the printer on after installing each
ink cartridge. On the other hand, in case of Stylus Pro5000, since the printer
itself does not have the function to perform initial ink charge, it is
recommended not to remove the ink cartridge from the printer during the re-
transport.

[Explaining the operation]
The motive power source of ink valve mechanism is PF motor. When the PF
motor is rotating, although ink valve mechanism is always receiving the
motive power, the cam loses its clutch in the clutch unit so that the cam to
operate the valve does not rotate more than 180 degree.
In the actual operation, when the printer is turned on, the valve is opened by
rotating the PF motor forward with initialization operation, and the valve
mechanism stays open, but stays always close in the non-printing condition.
