How to 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 each color of ink must be replaced after 11 bags (22 liters) of that ink
have been consumed. 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.
Note:
Air can accumulate in the ink filter when an ink bag that contains a small amount of air
is drained. Also new filters will contain air that must be released. You can prevent an
overflow of ink into the 0.2 micron filters associated with the purge valves in the top of
the carriage by bleeding any trapped air out of the ink filters.
Before you begin
IMPORTANT! Open the sliding maintenance station door to disable the ink pumps.
Close all four of the purge valves on the top of the carriage.
Required tool
Philips screwdriver (only if enclosure thumb-screws are too tight)
