Visually check if there are empty tubes:
a. Open the carriage.
b. Check the end of the tubes. They should appear as shown in the picture below. The rest of the ink
circuit can be checked for bubbles and ink. When the tubes are empty, they will have a bluish color.
When filled, the tubes will look darker and the yellow channel will have a slight magenta color (due
to the combination of ink color and tube color).

Root Cause
●
There are two primer channels. Yellow and Matte Black share one primer channel. Cyan,
Magenta, Gray, and Photo Black share the other primer channel. If one primer fails, one of the
groups might not get filled.
●
There are 2 Ink Supply Stations, If the missing colors are grouped as they are in the Ink
Supply Station, this issue can be related to that part of the printer.
