2.1 Overview

This Chapter describes the operating principles of the mechanism and electric circuits of Stylus PHOTO RX560/580/590.

2.1.1 Mechanical Components

The printer of Stylus PHOTO RX560/580/590 consists of the following major mechanisms:

Table 2-1. Mechanical Components 1

Mechanism Function/Description

Moves on the CR Guide Shaft right and left and performs printing on paper.

CR Assy

APG Assy

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.

Eject Assy

I/S Assy

The units and circuit boards constituting Stylus PHOTO RX560/580/590 are as follows:

Unit /Circuit Board Function/Description

Main Board

Power Supply Board

Panel Board Consists of two pieces located on the Middle Housing. Scanner Unit CIS consisting of 1200 dpi CCD for reflection (light source: LED)

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. Detects the current height of the carriage with the APG Sensor, and moves

the carriage up and down, driven by the PF Motor.

Driven by the PF Motor to eject the paper (CD-R Tray). As the Stacker is moved up and down (by manual operation), the paper eject

2.3 Banding Reduction System (BRS)/ Paper Feed Profile Correction (PFP)

 Overview

To ensure high-speed printing and high print quality, this printer is provided with the Banding Reduction System (BRS) and Paper Feed Profile Correction (PFP) function, which are outlined below:

Table 2-6. Outline of Banding Reduction System and Paper Feed Profile Correction Function

Supported Printing Mode

Outline

Conventional models perform overlapping printing (two-pass or fourpass printing) to reduce banding for ensuring high print quality. However, the printer provided with the Banding Reduction System

BRS

corrects the dot generation rate (amount of settled ink) for each raster, and performs one-pass printing. This function ensures both high print quality (reduction of banding) and high-speed printing.

The conventional paper feed adjustment method is such that the correction value calculated fr o m the data based on a specific part of the sheet is reflected to almost all over the sheet. Therefore, the conventional method cannot cope with the fluctuating error in the paper feed rate during paper feeding. However, the Paper Feed Profile

PFP

Correction function measures the error in the paper feed rate at each of minutely distributed measuring points on the sheet and provides a correction value for each point. Thus with this function, the printer realizes high print quality and high-speed printing on a supported paper type and in a supported printing resolution.

 How to prepare correction data

For each of BRS and PFP, print the relevant pattern for correction data preparation and read the printed pattern through the scanner. Then calculate the correction data and store the data in the serial flash ROM on the Main Board. The correction data are applied to printing in the supported printing mode.
