Abstract

According to an example, a liquid electrophotography printing (LEP) apparatus includes a fluid chamber to store fluid to be used to form an image and a filtration assembly to filter the fluid of the fluid chamber. The filtration assembly may store a filtration material to filter the fluid received from the fluid chamber and may provide the filtered fluid to the fluid chamber. The LEP apparatus may also include a detector assembly to detect a fluid parameter of the filtered fluid in the fluid chamber and a filtration adder unit to add a predetermined amount of the filtration material to the filtration assembly in response to a detection of the fluid parameter by the detector assembly.
