Epson Black Ink Cartridge T051190-SC740/760/860/SC1160
Also, even if the pump driver rotates epson sc740 ink absorption and the carriage position is in the false absorption position, only driving in the pump mechanism is performed and actual ink attraction is not done. Figure shows process of conveying motive power to epson sc740 pump drive roller. See Figure The process of conveying the motive power to the paper eject roller by rotating the pinion of PF motor is descried in figure 0. This motive power is conveyed to the Gear C through the Gear B. In the figure above, although the lever in order to drive Gear C, carriage lock, head cleaner mechanism is shown separately, it is constructed as one unit.
Since the engagement of these two parts depends on the tension of the compression spring, if the lever is burdened, only Gear C and pump roller rotate and no more motive power is conveyed to the lever part. Pump Drive Roller Figure In the ink absorptive operation epson sc740 as cleaning, flushing and initial ink charge except for printing operation, ink in the ink cartridge drains to the waste ink absorber pad through the cap by the pump unit drive.
In case of printing and flashing drive, ink is popped out by the PZT in the print head, but in case of absorptive operation such as cleaning and initial ink charge, ink absorption is performed only by the pump drive without PZT drive after the head surface is adhered to the cap. The next epson sc740 explains cap mechanism and relation between printer operation and cap. The absorber is spread in the cap and can hold a certain amount of ink which is absorbed from the head without draining it to the waste ink pad. Also, in the bottom of absorber, there are two valves in order to control adhesion of head and cap surface, and one exit to drain ink to the waste ink pad.

If the carriage is out of HP in this case, in the printable area or paper epson sc740 positionthe valves on the cap mechanism stays in the position A in the figure above and are always closed. In this condition, the carriage collides with flag, actual ink epson sc740 and slight ink absorption are performed.
Also, by moving epson sc740 carriage to further right side and colliding the flag for opening the valves with the frame, negative pressure is released in the state that head surface and cap are adhered. This makes it possible for ink on the nozzle plate surface to be ready for leaving from the cap in the stable condition. One of the major characteristic of this board is that the same secondary switch is used as Stylus Color series printer. Even if the switch is turned off during the middle of printer operation, since the driving power is turned off after the carriage goes back epson sc740 the carriage lock position, the possibility of clogging ink nozzle will be decreased.
If the switch is turned off when the papers in the printer are still being carried except for the papers in the hopper, the same operation mentioned above is performed and the driving power is turned off after the paper is completely ejected. L1 and R1-R2 also prevent high harmonic wave noise generated in the RC circuit epson sc740 which consist of C1-C4 and R1-R2 from going out, and eliminate the noise from outside here. At the point that this voltage drops at the certain voltage, C13 absorbs the current in the opposite direction and Q1 is quickly shut off by the resulting sharp drop. Basically, 42 V DC is output by these circuit operations and the number of T1 spiral coil.
Following explains each control and protection circuits. This circuit prevents voltage from dropping for constant output voltage. The output level is monitored by two Zener diodes. Operation of the secondary side switch is explained in the following page. This signal turns Q84 on and it becomes possible to discharge energy between of T1. At this time, even if the power is turned off, the electrolytic capacitor keeps Q84 on for a while. By this electrolytic capacitor, output is hold at least 30 seconds even after the power is turned off. This time helps the printer to complete the P-Off operation.
