HP 72SR manual Empty Excess Ink, Close the stopcock valve on the drain tube

Empty Excess Ink

Ink or cleaning solvent that has been expelled (“spit”) for ink jet maintenance or from a purge operation drains from the spit- toons and service station areas to excess ink containers. When the containers fill with ink, they should be emptied.

The excess ink container near the service station will need to be emptied when it is full or near full. This can be determined by visual inspection or when the float sensor reports a full condi- tion via the control panel.

The ink in the excess ink container near the capping station may evaporate at or near the same rate as it is collected, so it may never fill the container. Visually check the amount of ink peri- odically, and empty the container as needed.

Have a paper towel ready to catch the small amount of ink and cleaning solvent that will spill out of the drain tube as you dis- connect it. The excess ink container’s tray is designed to catch these spills for easier cleanup. You may also want to wear protec- tive gloves during this procedure.

1.Close the stopcock valve on the drain tube.

This prevents ink from continuing to flow out the end of the tube.

2.Disconnect the drain tube from the excess ink container.

3.(Service station reservoir only) disconnect the sensor cable from the float sensor.

4.Lift the container out of its tray.

5.Empty the excess ink and cleaning solvent into a solvent dis- posal container.

Note	Dispose of ink and cleaning solvent only according to
	the Material Safety Data Sheet (MSDS) and applica-
	ble laws and regulations. The MSDS is available on
	the MacDermid ColorSpan web site (www.color-
	span.com).

6.Replace the container in its tray.

7.Reconnect the drain tube to the container.

8.Open the stopcock valve on the drain tube.

9.(Service station reservoir only) reconnect the sensor cable to the float sensor.
