2.1.1.4.1 Pump, Carriage Lock, Head Cleaner Mechanism
In the EPSON Stylus Photo, there is no button or mechanism to change over the pump/paper feed
mechanism. Therefore, whenever the paper feed/pump motor rotate, the pump drive roller in the pump
unit inside rotates. However, ink absorbing/non ink absorbing are separated by the roller rotational
directions. Also, even if the pump drive roller(pump motor) rotates toward ink absorbing and the carriage
is in the false absorbing position, only driving in the pump mechanism is performed and actual ink
absorption is not done. The figure below shows process of conveying motive power to the pump drive
roller.
The process of conveying the motive power to the paper eject roller by rotating the pinion of PF motor
is shown in figure 2-12. This motive power is conveyed to the Gear C through Gear B.
In the figure above, although the lever in order to drive Gear C, carriage lock, head cleaner mechanism
is shown separately, it is constructed as one unit. Since the engagement of these two parts depends on
the tension of the compression spring, if the lever is burdened, only Gear C and pump roller rotate and no
more motive power is conveyed to the lever part.
