Component CR Unit Function Moves along the CR shaft to print on paper being powered by the CR motor. The unit includes Printhead, PW sensor, and CR encoder sensor. Moves the carriage upward/downward to adjust the platen gap being powered by the PF motor. There are 4 preset levels of platen gap and the unit moves the carriage to one of the levels according to the current carriage position detected by the APG sensor. Rotates the PF roller shaft to feed paper being powered by the PF motor. Being powered by the PF motor, feeds paper loaded on the ASF into the printer mechanism. Being powered by the PF motor, ejects paper or the CDR tray. The EJ frame moves corresponding to the stacker position so that the frame matches with the paper size.

Printer

Features of C691Main Board An EEPROM and a reset circuit are mounted individually to reduce the cost. This is achieved by removing a complex RTC circuit that is mounted on the previous model (R260/R265/R270/R360/R380/R390). Stylus Photo R280/ R285/R290 do not need the complex RTC circuit because a backup timer is not required for them.

Power switch read-in circuit LED driving circuit

Operations to reduce power consumption The printer carries out the following operations to go into sleep mode. Decreases the power voltage. Shuts off photoelectric current of photo interrupter sensors. Stops the motor drive circuit. Stops some part of the clock in the ASIC. De-energizes the motors. Makes the head drive circuit go into standby state.

2.3 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP)
Overview In order to ensure high print quality and high print speed, this product incorporates the Banding Reduction System (BRS) and Paper Feed Profile (PFP) Correction system. The overview of them is described in the table below. Table 2-6. Overview of BRS and PFP
Summary
Paper Type

Target Print Mode
Paper Size Resolutions (dpi)

Remarks

BRS

Conventional models perform overlapping printing (2-path or 4path print) to reduce banding problem. Printers that incorporate the Banding Reducing System do not perform the overlapping printing. They carry out 1-path printing correcting ink drop amount for each raster mode in order to avoid making a gap between each path (printed line). This enables to achieve both high print quality (less banding) and high print speed. In the conventional method to improve paper feed accuracy, the adjustment value is calculated based on a value obtained at a certain point of paper. Therefore, correcting the total paper feed amount (from when paper is fed and to when finishing printing) was impossible. The Paper Feed Amount Profile Correction offers more precise control over the paper feeding. Paper feed errors are measured at various points and a correction value is calculated for each of the points. This enables to ensure print quality in the target print mode.

Adjustment/Correction method

Correction values of the BRS and the PFP are automatically calculated when a pattern printed by the printer is scanned by a specified scanner. The created correction values are stored into the serial flash ROM on the main board, and applied when printing in the target print mode.

Revision B

3.1 Overview
This chapter provides how to troubleshoot problems analyzing the cause based on the messages shown by the printer driver, printer's LED status and the observed symptom. Identify and troubleshoot the problem referring to the tables on the following pages. When some parts need to be replaced, make sure to follow the procedure given in Chapter 4 and carry out required adjustments. If any abnormality is observed in motors or sensors, check the electrical value referring to the 3.1.1 "Troubleshooting on Motors and Sensors"(p.28).

3.1.1 Troubleshooting on Motors and Sensors
The following tables show the normal electric values of each motor and sensor. When any abnormality is observed in motors and sensors, check their electric values and compare them with the values given in the tables to see if the motors or sensors are broken or not. Table 3-1.
