(13) Remove four caps from the new print head.
(14) Remove each tube from the print head to be replaced with a new one, then attach each of the new caps which are
removed from a new print head to each tube, while exercising care to prevent any ink from being spilled.
<IMPORTANT>

Care is needed in preventing any ink from being spilled from each tube. If the ink is dripping, wipe off the dripping ink.

Be careful not to confuse it with the tube for the print head on the color side.

Be sure not to tighten the nut for part (a) by mistake. It could remove the tube and leak the contained ink.

When you replace the print head, be sure to move the carriage manually to the position of the platen at the center of the
printer before starting the replacement. If you perform the mounting of the head when the carriage is directly above the
maintenance unit, it may damage the maintenance unit or the heads.
<NOTE>

For a proper work operation, be sure to wear the printer-provided gloves.
