1.8.1 Printer Mechanism

Like the previous printer mechanism such as for Stylus Color 400, 600,

and Stylus Photo, one of the major characteristics of Stylus Color 440,

640, 740 is that the printers have no Engage/Disengage mechanism to

change between the pump mechanism and paper feeding mechanism.

In stead, this change-over control is done by the distinction between

turning direction of PF/Pump motor and position of present carriage

unit. Also, another major characteristic is that printhead is on unit

combining black and color.
