The printer mechanism is broken down into two broad sections: the passage and paper passage.
Consisting mainly of a carriage unit that houses ink tanks and a printhead, and a maintenance cartridge, the ink
passage supplies, circulates, sucks and otherwise handles inks.
The paper passage consists of such mechanical components as a paper unit and is designed to feed, convey and
deliver paper in two ways.
A summary description of each mechanical component is given below.
