Changing black inks. You can set the change of black ink to automatic, or you can manually switch between Matte (Mk) and Photo (Pk) inks. In the past this was a distinct problem with Epson printers if, like me, you used both matte (art) papers and glossy papers.

When ionic substances are dissolved in water they do not exist as the pure substance (i.e. NaCl) but as dissociated ions (i.e. Na+ and Cl-). These ions respectively carry a positive and negative charge. Water (H2O) is a polar molecule meaning that it has a positive (on the hydrogen atoms) and negative (on the oxygen atom) dipole moment. When NaCl is dissolved in water, the Na+ ions attract the negative dipole moment of H2O and the Cl- ions attract the positive dipole moment of H2O.
