Epson Stylus D88 Instruction Manual page 9

Remove the backing tape from the black
clamp on the tubes and fit it to the printer
housing as shown.
Plug the printer back into the mains
supply and the printhead will move back
and forth then perform it's initial ink
charge.
During this ink charge you should see the
ink flowing through the tubes near the
connectors.
The air you may see in the tubes is not signifi-
cant and will not affect the operation of the
system in any way.
