Replacing the print heads
Be sure to observe the following precautions when replacing a print head.
CAUTION
• As a safety precaution, store print heads in a location out of the reach of small
children.
• If ink is licked or ingested accidentally, consult a doctor immediately.
IMPORTANT
• Be sure to use only the Graphtec print heads designed for the JW220 printer
(part numbers IH-90001BK, and IH-90002CMY).
• Do not touch the metallic parts of the print head or the print head section itself.
Such actions will adversely affect the printing. Moreover, there is a risk of
damage to the print head from static electricity.
• Do not drop or shake the print heads or ink cartridges. Such actions may cause
the ink to leak or spatter, with the risk of staining your surroundings and cloth-
ing. Moreover, the head section may become damaged, making the print head
unusable.
• Make sure that the printer is in the power-on status when replacing a print head.
Replacing a print head when the printer has been turned off may cause the print
head to malfunction.
