How to Replace Epson CX7450 Ink Cartridges (8 Steps)

1. Lift the entire scanner unit on your Epson CX7450 by its sides, gently, until it rests at an angle in an open position.
2. 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.
3. Grip the cartridge cover and pull it gently toward you to reveal the ink cartridges.
4. 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.
5. 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.
6. Replace other cartridges one by one as needed.
7. Flip the cartridge lid over the cartridges and press down to secure it in place.
8. 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.
