Replace Ink Filters

The control panel displays a Warning message on the control panel when 20 liters of ink has passed through the filters. Replace all five the filters as a set. Failure to replace the filters when recommended will eventually cause the filters to clog and prevent ink from reaching the printheads.

Have a paper towel ready to catch the small amount of ink or cleaning solvent that will spill out of some of the tubes and the filter itself as you disconnect them. The reservoir shelf is designed to catch these spills for easier cleanup. You may also want to wear protective gloves during this procedure.

1.Disconnect the tube from the ink or cleaning solvent reser- voir.

Unscrew the tube connector and disconnect the tube. See Fig. 5-11 for location.

2.Disconnect the level sensor cable from the reservoir.

Press down on the cable connector tab to release the connector. See Fig. 5-11 for location.
