The printer mechanical system can be roughly divided into two major components: the ink passage and paper path.
The ink passage consists of ink tank unit and a carriage unit where printhead are installed, purge unit, and maintenance cartridge and performs the supply,
circulation, and suction/removal of ink.
The paper path is comprised of the paper feeder and performs two types of paper feeding, transport, and discharge of media.
This section presents an overview of the components of the mechanical system.
