How to Replace Epson CX7450 Ink Cartridges

The Epson Stylus CX7450 is an all-in-one printer, scanner and copier that prints using four ink cartridges—one black cartridge and three colored cartridges (cyan, magenta and yellow). A flashing LED light to the left of an ink drop icon on the printer console indicates that the ink is running low. When the light stops flashing, you must replace the ink cartridge to continue printing as the other cartridges won’t work when one cartridge is spent. Replacing a spent ink cartridge with a new cartridge isn’t difficult and requires little beyond accessing the ink cartridge holder inside the printer underneath the scanner.

Step

Lift the entire scanner unit on your Epson CX7450 by its sides, gently, until it rests at an angle in an open position.

Step

Push the "Stop" button. The cartridge holder moves to the center, where the spent cartridge lines up with the empty droplet image featuring a diagonal line through it, on the printer housing. Push the “Stop” button again. Each spent cartridge will line up with the droplet image. If the remaining cartridges contain sufficient amounts of ink the holder moves to the right side of the printer.

Step

Grip the cartridge cover and pull it gently toward you to reveal the ink cartridges.

Step

Unlock a cartridge from the holder by pressing its grooved tab. Grip the cartridge between your fingers and pull it straight up and out of your printer.

Step

Pull the yellow tape from the bottom of the replacement cartridge and insert it into the cartridge holder—pressing down on the cartridge to make certain that the electrical contacts meet.

Step

Replace other cartridges one by one as needed.

Step

Flip the cartridge lid over the cartridges and press down to secure it in place.

Step

Return the scanner carefully to its original position, press the "Stop" button and wait for the power "On" light to stop flashing (approximately two minutes). When it stops, begin printing.
