 If the print quality does not improve even after one or two cycles of Head Cleaning B or the display screen indicates "Open top cover and replace the printhead", it may be time to replace your printhead.

Follow the steps below to properly replace your printhead.


Precautions when handling the Printhead

Take the following precautions when handling the printhead:
  • For safety, keep the printhead out of the reach of children.
  • If ink is accidentally ingested, contact a physician immediately.
  • Do not touch the printhead immediately after printing. The printhead becomes extremely hot, and there is a risk of burns.
  • When replacing the printhead immediately after printing, wait a few minutes before replacing it. The metal parts of the printhead become hot during printing, and there is a risk of burns from touching these parts.
  • There may be ink around the nozzles of the printhead you remove. Handle the printhead carefully during replacement. The ink may stain clothing.
  • Do not open the printhead pouch until immediately before installation. After removing the printhead from the pouch, install it right away. If the printhead is left after the pouch is opened, the nozzles may dry out, which may affect printing quality.
  • Your hands may become dirty during printhead replacement. Use the gloves provided with the new printhead for replacement.
