Epson Stylus CX745 printer is capable of counting the number of pages an ink cartridge can print. This notifies the user when to change the ink cartridge. Sometimes, these automatic notifications can pose a problem if you use refilled cartridges or print plenty of coloured photographs. If you find your Epson Stylus CX7450 giving faulty notifications, simply reset the ink counters by performing a Factory Reset.
Switch the printer off and disconnect printer cable plugged into the back of the printer.
Press and hold three buttons on the printer, the "Load" button, "Black cleaning" button and "Color Cleaning" Button and turn on the printer. Release the buttons when the printer powers on.
Press and hold the “Load” button for two seconds within a second after Step 2.
Release the “Load” button. The printer will be reset to its default settings and will acknowledge the ink level of the cartridge. However, if it does not work and the printer still shows faulty ink level, you will have to reset the cartridge as well. In that case, continue to Step 5.
Press the “Pause” button on the printer. Now press and hold down the “Load” button for about six seconds. You will see that the power light starts to blink.
Lift the cartridge clamp all the way up when the printer head moves to the left after Step 5. Now clamp it down again. Make sure you do not take out the cartridge.
Push and release the “Load” button once you close the clamp. The cartridge will also be reset now and the printer will acknowledge the current ink level of the cartridge.
