Apparatus and method for applying release fluid to a leveler in a printing apparatus

An apparatus comprising:

• a substrate path that transports a substrate with marking material;
• a marking material leveling system having a marking material leveler;
• at least one release fluid spray nozzle that pulse sprays release fluid to the marking material leveling system, where the marking material leveler with the release fluid levels marking material on the substrate;
• and
• a controller that determines an adjusted amount of release fluid to spray to the marking material leveling system,
• wherein the at least one release fluid spray nozzle pulse sprays the adjusted amount of release fluid to the marking material leveling system.

A method in an apparatus including a substrate path, at least one release fluid spray nozzle, and a marking material leveling system having a marking material leveler, the method comprising:

• transporting a substrate with marking material along the substrate path;
• pulse width modulation spraying release fluid to the marking material leveling system using the at least one release fluid spray nozzle;
• leveling marking material on the substrate using the marking material leveler with release fluid;
• determining an adjusted amount of release fluid to spray to the marking material leveling system;
• and
• pulse width modulation spraying the adjusted amount of release fluid to the marking material leveling system using the at least one release fluid spray nozzle.
