2.1 Overview

This Chapter describes the operating principles of the mechanism and electric circuits
of Stylus PHOTO RX585/595/610.

2.1.1 Mechanical Components

The printer mechanism of Stylus PHOTO RX585/595/610 consist of the following
major mechanisms:
Table 2-1. Mechanical Components 1
Mechanism
Moves on the CR Guide Shaft right and left and performs printing on paper.
CR Assy
The Carriage Assy incorporates the Printhead, PW Sensor, and CR Encoder.
The drive source is the CR Motor.
Controls the platen gap in four stages.
APG Assy
Detects the current height of the carriage with the APG Sensor, and moves
the carriage up and down, driven by the PF Motor.
PF Assy Driven by the PF Motor to turn the PF Roller Shaft for feeding paper.
ASF Assy Driven by the PF Motor to load paper into the Printer Mechanism.
Driven by the PF Motor to eject the paper (CD-R Tray).
Eject Assy
As the Stacker is moved up and down (by manual operation), the paper eject
frame moves up and down so that its height can be adjusted to the media.
Located in the right end of the mechanism, performs capping the Printhead,
I/S Assy while it is not used, and sucking waste ink. The waste ink is sent to the Waste
Ink Tray via the Waste Ink Tube.
The units and circuit boards constituting Stylus PHOTO RX585/595/610 are as
