The printer mechanism is broken down into two broad sections: ink passage and paper passage.
The ink passage consists primarily of the carriage unit[2] that houses ink tanks[1] and a printhead, purge unit[3] and maintenance cartridge[4], and supplies, which
circulates, sucks and otherwise handles inks.
The paper passage consists of mechanical components, such as the paper feed unit[5], which is designed to feed, convey and deliver paper in two ways.
A summary description of each mechanical component of the printer is given below.
