【单选题】To replace an ink cartridge on your printer:
Step 1, Turn ON the printer. Open the top cover. The printer’s ink cartridge holder will move to the center. The Power ON light will begin blinking;
Step 2. Release the blue lever over the ink cartridge holder by lifting it up.
Step 3. Hold the top of the empty ink cartridge and gently lift it upward until it comes loose.Discard the cartridge, being careful not to spill any remaining ink.
Step 4. Remove the cellophane wrapping from a new ink cartridge. Peel away the yellow protective strip from the head of the cartridge.
Caution: Once you have removed the yellow protective strip, do not touch the ink nozzles or the metal strips. This can damage the head and result in poor print quality or print failure.
Step 5. Set the new ink cartridge into the open slot in the holder.Align it and gently press downward until the ink cartridge clicks into place.
Step 6. Lower the blue lever until it snaps over the ink cartridges.
Step 7.Close the cover of the printer. When the Power ON light stops blinking, the printer can begin printing. If you’d like to run an optional print test, hold the Power ON button down for 3 seconds. If you encounter any printing problems, please consult the Troubleshooting section in your instruction manual.
