2.1 Overview

This chapter explains the operating principles of the mechanical sections and electrical circuits in this product. The main components of this product are as follows.
Control circuit board : C698 MAIN
Power supply circuit board : C698 PSB/PSE
Control panel board : C698 PNL
LED board : C698 PNL-B

2.2 Printer Mechanism

Like the conventional model, this product uses DC motors and stepping motors as power sources. The following table describes the motor types and their applications.

Used for carriage driving. Makes little noise during driving. The CR linear scale and CR encoder sensor are used to control the motor.
Drives the Paper loading rollers at the time of fixed­value paper loading or paper feed/eject operation. To grasp the paper feed pitch, the precision gear surface is fitted with the PF scale and the PF encoder sensor is used to control the motor.
Drives the Carriage Unit at the time of PG setting. The two APG Sensors are driven vertically to control the motor.
Drives the paper feed operation of the ASF. Since this is a stepping motor, any scales or photo sensors to know the driving conditions are not required.
Drives the pump, wiper, etc. of the Ink System. Since this is a stepping motor, any scales or photo sensors to know the driving conditions are not required.
The basic mechanism is almost same as the Stylus Photo R1800. The schematic diagram below shows the printer mechanism.

3.1 Overview

This chapter describes unit-level troubleshooting.

3.1.1 Troubleshooting according to Error Messages

After checking the printer LED and STM3 error indications, you can grasp the fault location using the check list in this section. When you find the fault location, refer to Chapter 4 “Disassembly and Reassembly” and change the corresponding part and/or unit. The following table indicates the check point reference tables corresponding to the error states (LED and STM3).
