The mechanisms that supply the ink from the ink cartridges to the print heads are identical
for both printer models. However, the number of components and their arrangement are
slightly different.
The operation of the basic components is first explained with the J007/J010 as a model
then the differences of the J011 are described.

An air sensor [1], two feelers [2], and head tank [3] comprise the reservoir of the ink

that expands upon application of a electrical charge to force ink out of the nozzles of the
print head [5].
