Chapter 22-92.3 Printer Mechanical System2.3.1 Outline2.3.1.1 Outline0008-6339The 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.F-2-72.3.2 Ink Passage2.3.2.1 Ink Passage2.3.2.1.1 Overview of the ink passage0008-6340The ink passage consists of the ink tanks, printhead, caps, maintenance jet tray, maintenance cartridge, ink tubes for connecting the mechanicalcomponents, and ink suction pump that is activated when ink is removed. These components are used to perform the supply, circulation, and suction/removal of ink.A schematic diagram of the ink passage (for one color) and the ink flow are shown in the figure below.Ink tank unitPurge unitCarriage unitPaper feedMaintenance cartridge
