The printer allows black (K) to print with color cyan, magenta, yellow (CMY) at the same time (known as CMYK printing). To ensure proper printing, the black and color cartridges need to be correctly aligned. The alignment procedure should be done whenever replacing any of the cartridges. Follow this procedure to align the cartridges:
  1. Turn on the printer. When the startup completes, the "ON LINE" screen displays.
  2. Press the Cartridge/+ button.
  3. Replace the ink print cartridge if not already done. The "Press a key when print heads replaced" prompt displays. Press any button to continue.
  4. When the "Reset color (or black) Ink..." prompt displays, press the Cartridge/+ button to reset the ink if a new cartridge was installed; otherwise, press the Eject/- button if only performing the alignment procedure.
  5. When the "ALIGN INK CARTRIDGES" prompt displays, press (+).
  6. When the "--COLOR ALIGNMENT--" prompt displays, insert an envelope into the printer and press the Enter button.
