Empty excess ink (page 5-6)

Replace ink filters (page 5-18)

The excess ink containers on the printer stand legs should be emptied when half full. When the container under the service station is full, the control panel displays an Action message, and no further Purge-n-Wipes and idle spits will occur until the container is emptied.

Replace all five filters as a set, to prevent ink pump failure. The control panel will display a Warning message when 20 liters of ink have passed through the set of filters. You may con- tinue printing past this point, but printhead fill errors may occur.
