Summary:Systems, apparatuses, and methods of fluid delivery for liquid electrophotography printing. A fluid delivery apparatus includes a charged ink source, a supplemental fluid source, a working suspension tank in fluid communication with the charged ink source and the supplemental fluid source, a sensor, and an optical density control unit. The charged ink source is to store a charged ink mixture including charge directors and toner particles. The supplemental fluid source is to store a supplemental fluid including imaging oil. The working suspension tank is to store a working suspension mixture including the charge directors, the toner particles, and the imaging oil. The sensor is to monitor an optical density of print output of the liquid electrophotography printing apparatus. The optical density control unit is to determine whether to supply an uncharged ink mixture to the working suspension tank in response to the monitored optical density indicating electrical fatigue.
