PF Pump Motor Drive Circuit

Epson Pic Encoder Printer

IC15 LB1845 on C206 Main-B, C255 Main board, IC15 UDN2917 on C256 Main board, and IC12 13 A3956 on C257 Main board are used for driving PF Pump motor. In the IC, Bi-pola drive PWM current control type is performed, making it possible to provide stable current to each phase of motor. Also, it makes possible to change over the reference voltage as drive current settings by making few combinations using current setting ports input . However, firmware does not support Micro-step in the Stylus Color...

C Psbpse and C Psbpse Power Supply Board for Stylus Color

C206 Block Diagram

There are 2 types of power supply boards for Stylus Color 440 640 740. The main components of the boards are the same, but the 5V regulator ICs which create steady 5V are different. These boards are power supply board with a RCC switching regulator, which generates 42VDC for drive part and 5VDC for logic part to drive the printer. One of the major characteristic of this board is that the same secondary switch is used as Stylus Color series printer. By using this switch, the following difference...

Adjustment by Adjustment Program

In this printer, it is necessary to set the correct information for each printer mechanism in order to maintain consistent printing function and quality, eliminating difference of each printer mechanism's characteristics. Therefore, in case that the combination of the printer mechanism and main board changes or the printhead is replaced during repair, you must set and save the correct information to the main board, using the exclusive adjustment program. The adjustment program Program name...

Pump Carriage Lock Head Cleaner Mechanism

Epson 300 Gear Motor

In the Stylus Color 440 640 740, there is no switch or mechanism to change over the pump paper feed mechanism. Therefore, whenever the paper feed pump motor rotate, pump drive roller in the pump unit inside rotates. However, ink absorption non ink absorption are separated by the roller rotational direction. Also, even if the pump driver rotates toward ink absorption and the carriage position is in the false absorption position, only driving in the pump mechanism is performed and actual ink...
