Replacing An Ink Tube

To ink trays

From printheads

Fig. 3-11. Ink tube routing

Replace an ink tube when switching ink colors or types, or if the ink tube leaks. You need not replace an ink tube when you change an ink reservoir and/or printhead without changing ink color or type, if the tube is functioning normally.

Each of the ink tubes is routed to a specific ink tray position, to enable the replacement of individual tubes without crossing or tangling with other tubes.

Caution	Always remove and replace ink tubes one at a time,
	to ensure correct routing of the tube. Although the
	printer can detect the proper placement of the ink
	reservoirs and printheads, it cannot detect whether
	the ink tubes are routed correctly. Incorrectly routed
	ink tubes would likely mix inks in the printhead, and
	cause printing problems.
Tip	Wear protective gloves during this procedure to pro-
	tect your hands from ink stains.
