The ink passage consists primarily of carriage unit[2] that houses ink tanks[1] and a printhead, purge unit[3] and maintenance cartridge[4], and supplies, circulates,
sucks and otherwise handles inks.
The paper passage consists of mechanical components, such as a paper feed unit[5], and is designed to feed, convey and deliver paper in two ways.
