EPSON Stylus COLOR 670 Revision A 2.1.2 Printhead The printhead uses a new developed E-CHIPS+ 1 head method and EPSON Stylus COLOR 670 can perform multiple shot printing and variable printing. Printhead nozzle configuration is as follows.
EPSON Stylus COLOR 670 Revision A 2.1.2.1 Printing Process Ink Path PZT Ink Cavity This section explains the process in which the printheads of On-Demand inkjet printers eject ink from each nozzle. 1. Normal State: When no printing signal is sent from PC, or no PZT drive voltage is applied, PZT does not change shape, therefore PZT does not squeeze the cavity. Ink pressure inside the cavity is kept normal. (Refer to Figure 2-3.
EPSON Stylus COLOR 670 Revision A 2.1.2.2 Printing Method For print dot system, EPSON Stylus COLOR 670 has the following two types of printing modes. n Multiple shot printing n Variable dot printing The above two printing modes are automatically selected depending on the media and the resolution setting. The following explains each printing mode. o Multiple shot printing This printing mode is developed to improve the print quality on plain paper or transparencies in low resolution.
EPSON Stylus COLOR 670 Revision A 2.1.3 Carriage Mechanism 2.1.3.1 Platen Gap (PG) Adjustment Mechanism The carriage mechanism consists of carriage motor (CR motor), carriage unit (including printhead), CR timing belt, CR guide shaft, CR guide frame, CR home detector (HP sensor) etc. The PG adjustment mechanism is designed to keep the platen gap correct for the paper thickness to prevent ink from smearing.
EPSON Stylus COLOR 670 Revision A 2.1.4 Paper Feeding Mechanism When DE (disengage) lever is at normal position, torque from the PF motor is sent to the PF roller and paper eject roller as described below. The paper feeding mechanism consists of paper feed motor (PF motor), PF roller, paper eject roller, paper guide, and so on. o To the PF roller: The paper feeding mechanism feeds paper loaded from ASF using the PF roller and paper eject roller.
EPSON Stylus COLOR 670 Revision A 2.1.5 Paper Loading Mechanism (ASF Unit) The paper loading mechanism is positioned at the printer rear and consists of paper load roller, paper return lever, hopper, and so on. The paper loading mechanism loads paper at the ASF unit and feeds paper to the PF roller. The ASF unit uses a PF motor. Drive sent from this motor is switched between the ASF unit side and Pump/PF roller side by the disengage mechanism when the CR unit moves to the left end of the CR guide shaft.
EPSON Stylus COLOR 670 Revision A Torque sent from the ASF/Pump motor to the ASF unit via the disengage mechanism. ASF paper loading sequence is described below. 1. When the printer is powered on, the CR unit moves to the DE lever switching position and switches DE position to the ASF side. PF motor revolves CW and ASF home position is detected by ASF HP sensor. Then PF motor revolves CCW, drives paper return lever and return the paper to the stand-by position. 2.
EPSON Stylus COLOR 670 Revision A 2.1.6 Ink System Mechanism Figure 2-9 shows the operating principles of the pump mechanism. Ink system mechanism consists of Pump unit (including CR lock mechanism) and Capping mechanism. Counterclockwise Clockwise Ink system mechanism drives the Pump unit that presses cap to the Printhead and ejects ink from Ink cartridge, Head cavity and Cap to the Waste ink pad.
EPSON Stylus COLOR 670 Revision A 2.1.7 Capping Mechanism Stylus COLOR 660 has built-in air valves in the capping unit but Stylus COLOR 670 uses valveless system. The Capping mechanism covers the Printheads with the cap holder to prevent the ink around the nozzles from increasing viscosity when the printer is in stand-by mode or when the printer is off. Capping mechanism moves up when the CR unit moves to the right end of the CR guide shaft and covers the printhead nozzle plate.
EPSON Stylus COLOR 670 Revision A n CL2 2.1.8 Ink Sequence o Initial ink charge - Ink absorption (Black Ink: 0.47ml, Color Ink: 0.73ml) After the product is purchased and the printer is turned on for the first time, the printer performs the initial ink charge and charges ink inside the head cavity. When the initial ink charge is completed properly, the printer releases the flag inside the EEPROM and no initial ink charge will be performed next time the power is turned on.
EPSON Stylus COLOR 670 Revision A 2.2 Electrical Circuit Operating Principles The electric circuit of the Stylus COLOR 670 consists of the following boards. o Main board: C301MAIN Board o Power supply board: C301PSB/PSE Board o Panel board: C209PNL Board 2.2.1 C301PSB/PSE Board The power supply boards of Stylus COLOR 670 use a RCC (Ringing Chalk Converter) circuit, which generates +42VDC for drive line and +5VDC for logic line to drive the printer.
EPSON Stylus COLOR 670 Revision A o +5V line constant voltage control circuit: + 4 2 V D C + 5 V D C The output level of the +5VDC line voltage is monitored by the regulator IC51. If abnormal voltage is detected, the information is fed back to the internal comparator.

EPSON Stylus COLOR 670 Revision A o Printhead Driver CircuitHead common driver circuit 2.2.2.2 Printhead Driver Circuit The printhead driver circuit consists of the following two components: n Head common driver circuit (Common driver IC15 & Wave amplifier transistor Q2, 3) n Nozzle selector IC on the printhead driver board. The common driver (IC15) generates a reference drive waveform according to the output signals from the ASIC (IC2).
EPSON Stylus COLOR 670 Revision A 2.2.2.3 PF Motor (PF/ PUMP/ ASF Motor) Driver Circuit The motor driver IC (IC14) on C301MAIN drives PF/ PUMP/ ASF motor. Stylus COLOR 670 uses 4-phase 48-pole hybrid type stepping motor and performs constant current bi-polar drive. ASIC (IC2) converts PF motor phase control signal to LB11847 micro step drive form and outputs to motor driver IC (IC14) LB11847 from port 107, 118. Based on this signal, IC14 determines the phase mode.
EPSON Stylus COLOR 670 Revision A 2.2.2.4 CR Motor Driver Circuit 2.2.2.5 Reset Circuit Motor driver IC (IC13) on C301MAIN board drives CR motor. Reset circuits consist of reset/ timer IC (IC5) and peripheral elements. Reset circuits are attached on the C301MAIN board to monitor the two voltages: +5V for the logic line and +42V for the drive line. When each circuit detects abnormality on the corresponding line, it outputs a reset signal to reset CPU (IC1) and ASIC (IC2).
EPSON Stylus COLOR 670 Revision A 2.2.2.6 EEPROM Control Circuit Since EEPROM is nonvolatile memory, it keeps written information if the printer power is turned off. When the printer is turned ON, ASIC reads data from EEPROM (IC6) and when the power is turned OFF it stores data to EEPROM. Information stored in EEPROM is listed below. n Various ink counter (I/C consumption counter, waste pad counter, EEPROM is connected to ASIC with 4 lines and each line has the following function.
EPSON Stylus COLOR 670 Revision A o Black/ Color cartridge sensor (COB/ COC) 2.2.2.7 Sensor Circuit C301MAIN is equipped with the following five sensors to detect the status of the printer. o HP Sensor HP sensor uses photo interrupter method. HP sensor detects the carriage HP (home position). HP is the standard position for the print start position. When CR unit is within the home position, the sensor outputs +5V: When CR unit is out of the home position, the sensor outputs 0V.
