Note: Remember to drain the remaining ink. If the ink is not drained, it may spill out.
Note: Alternatively, you can use the drainage tube (3 mm dia.) on the bottom of the overflow pan to drain the
ink into an empty plastic bottle or other container.
11) Use two Scissor clamps to clamp the ends of the three-way joint of the waste ink tube. (Clamp the tube on the
side that flows to the Waste ink tank and the tube that comes down from the Ink cartridge holder.)
Then from the three-way joint, unplug the tube coming down from the Overflow pan and cap the port on the
three-way port and unplugged tube with rubber cap. (Rubber caps are supplied with the new Overflow pan.)
