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.
  • 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 unless replacement is necessary. After removing the Printhead from the pouch, install it right away. It the Printhead is left exposed after the pouch is opened, the nozzles may dry out, which may affect printing quality.
