Printer Mechanism
The Stylus 1500 printer mechanism is composed of the printhead unit; paper feed, carriage drive,
pump, and push tractor feed mechanisms; and various sensors. The figure below shows a
functional block diagram of the printer mechanism. Depending on the position of the carriage unit,
the paper feed motor torque is transmitted to the paper feed, auto sheet feed, push tractor feed, or
pump mechanisms via a disengage mechanism.
