Take the following precautions when handling the Printhead.
Caution
• 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.

ment. The ink may stain clothing.

affect printing quality.
