PF Motor Driver Circuit

The PF motor for this printer operates the following The gate array E05B33 IC6 outputs the phase drive control signals PFAPH and PFBPH , phase data PFAO 1 and PPFB1 0 and voltage reference data PFV to the driver IC UDN2917EB IC16 . The driver IC then controls the phase current based on the voltage reference data. This sequence enables the micro step with a minimum of 1 720 inch at 2-2 phase. Figure 2-23.

Carriage CR Unit Removal

1. Remove the printer mechanism unit. Refer to Section 3.2.6. 2. Remove the extension spring to release the timing belt. Refer to the step 2 in Section 3.2.10.1. 3. Disengage the timing belt from the pulley and sub pulley in the CR motor assembly. 4. Remove 2 E-rings and 2 plain washer from the both edges of the CR guide shaft. 5. If the head cleaner lever in the pump unit is locking the CR unit, push the lever down manually to release the CR unit. 6. Remove 1 securing the head FFCs and FFC...

Head GAP Adjustment

This operation is required when the black color head or the both heads are removed or replaced. It is performed to align the vertical lines between black and color heads. 1. Connect the printer and the host computer with a parallel interface cable. 2. Run the adjustment program in the host computer. 3. Input the customer data. Refer to Section 4.1.2. 4. Move the cursor using T or I key to select ADJUST in the 1st menu. Then press the Enter key, and the main menu appears on the monitor. 5. Move...

The CR mechanism is composed of the CR unit, timing belt, CR guide shaft, paper eject frame, HP sensor Home Position sensor and CR motor. The CR motor sends torque to the timing belt to move the CR unit in the both right and left directions along the paper eject frame and CR guide shaft. A stepping motor used for the CR motor enables the CR unit to move and stop at any position. The CR is primarily detected at the home position by HP sensor when the printer is turned on and its position is then...

The paper feed mechanism of this printer consists of the integrated ASF Auto Sheet Feeder mechanism, tractor mechanism, PF Paper Feed motor, front rear PE Paper End sensors, PF roller, paper guide mechanism, paper eject unit, and PF motor drive disengage mechanism. The torque from the PF motor drives the paper load mechanism, paper feed mechanism and paper eject mechanism. While the printer is not printing, the PF motor drive disengage mechanism switches the torque from the PF motor to the pump...

Finding out the Head Voltage

Normally, the head voltage is not acknowledged without checking the head ID by removing the head. This program is, however, designed to read the head voltage data stored in the EEPPROM on the MAIN Board. This section described how to find out the head voltages. 1. Connect the printer and the host computer with a parallel interface cable. 2. Run the adjustment program in the host computer. 3. Input the customer data. Refer to Section 4.1.2. 4. Move the cursor using T or I key to select ADJUST in...

Initialize Operation

This operation is performed to write the factory values in the EEPROM on the MAIN board. With this operation, the factory values are written in at a time. 1. Connect the printer and the host computer with a parallel interface cable. 2. Start the adjustment program in the host computer. 3. Select CUSTOMER SET in the 1 st menu and press the Enter key. 4. Move the cursor using T or I key to select an appropriate customer code and area. Then press the Enter key, and the main menu appears on the...

Counters

This printer is equipped with following counters. The values for the counters are stored in the EEPROM on the MAIN control board. This counter is used to manage the total amount of drained ink. If the counter value exceeds 65,000, the maintenance error occurs and the current printing job stops consequently. Refer to Section 1.4.11. This error requires EEPROM clear and waste ink drain pad replacement. Refer to Section 1.4.3 and Section 3.2.9. The current value for this counter can be found in...

EPSON Stylus COLOR CR Motor Driver Circuits

The CR motor driver IC SLA7043M IC15 sends motor phase data using the serial data XCRCLK, XCRSTB, CRASERI, CRBSERI and voltage reference data CRV from the gate array E05B34 to the driver to control the phase current in the driver. The data output from the phase A and phase B CRASERI, CRBSERI are transferred synchronizing with the clock signal XCRCLK . Then the data is read at the driver IC by the strobe signal XCRSTB . This sequence enables the micro step with a minimum of 0.026 mm pulse driven...
