(→P.566) Precautions when handling the Printhead Take the following precautions when handling the Printhead. Caution • For safety, keep the Printhead in a place inaccessible for 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 • Avoid dropping or shaking the Printhead. Otherwise, ink may leak and cause stains. • 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 store a Printhead temporarily before installation, do not keep the nozzles and metal contacts (→P.573) facing down. If the nozzles or metal contacts are damaged, it may affect the printing quality. • Never attempt to take apart or modify a Printhead. This may damage the printer. • Never touch the Printhead nozzles or the metal contacts. This may cause printing problems. Maintenance 569
