Assembling Note:
- When assembling the Supply valve ASSY, be sure to thoroughly clean the L joint of the
Tube from the Ink refill unit and the joint of the Sub tank before assembling it.
- When the Supply valve ASSY has only one Valve ASSY, replace it with the one having
two Valve ASSYs. In this case, the length of the Tube to connect the Supply pump and
Supply valve ASSY is different, and therefore be sure to replace the Tube with a new
appropriate one.
- When assembling the Supply valve ASSY with two Valve ASSYs, be sure to follow the
procedures given below:
