Change Ink Filters

Introduction
Each ink color has a filter that removes any particulate matter from the ink as it is
pumped from the ink bag toward the printheads. The ink filters are located at the
electronics end of the printer around the corner from the ink bags.
When to do
The ink filter for a particular color of ink must be replaced after 11 bags of that ink
have been consumed. The printer monitors ink use and provides a warning when it
is time to change an ink filter. If an ink filter becomes clogged it will trap color
pigment and affect the color balance of printed images so it is important to change a
filter before this occurs.
If the Nozzle Check image prints one color weaker than normal, this is an indication
that the ink filter for the affected color is clogged and the filter must be replaced.
Before you begin
IMPORTANT! Open the sliding maintenance station door to disable ink pumps.
Disconnect the ink couplers on all ink bags.
Close all four of the vacuum shut-off valves on the top of the carriage.
Required tools
