Abstract: A cleaning system that includes a meter operatively connected to a cleaning device, and where the flow of waste water activates the cleaning device, and which device removes contaminates from the meter.

Abstract: Devices and methods for a vertical float system. A float guide, located in a tank containing a fluid, has first and second sections with a first diameter and a third section between the first and second section. The third section has a smaller, second diameter. A float is slidably attached to the float guide in the third section. The system includes a switch and a level sensor located in the first section or the second section. The switch becomes activated when the float contacts the level sensor. One of an inner face of the float and the third section of the float guide has projections arranged in a contiguous pattern around the one of the inner face of the float and the third section of said float guide. The projections are shaped to establish point contacts between the float and the float guide in the third section.

Abstract: The present disclosure is a simple method to compensate for development starvation in an existing development control system already using solid area development and halftone development patches. By using a small aperture specular sensor, it is possible to measure the starvation and compare with a standard. Defect level can then be addressed by correcting toner concentration to reduce the image density defect at the solid/halftone boundary.
