When Uneven Color Issue Occurs

Light Choke Cleaning

Light choke cleaning consumes a large amount of ink. Frequently performing light choke cleaning
makes the print heads more likely to be damaged. Avoid using it more than necessary.
If nothing is printed for an extended period, color may be uneven and unstable, i.e. darkness or brightness is
different though the same data is printed with the same settings. In that case, perform the light choke clean-
ing. To obtain stabilized print color, stir the ink.
