Precautions when handling the Printhead
Take the following precautions when handling the Printhead.

Attention:

• 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.

Important:

• 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.
• If you need to put a Printhead somewhere temporarily before installation, do not keep the nozzles and metal contacts facing down. If the nozzles or metal contacts are damaged, it may affect the printing quality.

Replacing the Printhead attention:

• 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.

Note:

• Prepare a new Ink Tank when ink levels are low.
• Your hands may become dirty during Printhead replacement. Use the gloves provided with the new Printhead for replacement.
• Choose On in Auto Print to have the printer automatically adjust the Printhead alignment after replacement of the Printhead.
