Abstract
A method for measuring a width of a contact zone between a surface, having movement, and a cleaner brush, having a detoning member, the surface having a toner image thereon, the contact zone having particles of the toner image removed from the surface, 'comprising the steps of developing the toner image on the surface, the toner image having sufficient width to overlap the cleaner brush; moving the toner image into direct alignment with the cleaner brush; stopping the movement of the surface; rotating the cleaner brush against the surface to remove the toner image from the surface in the contact zone; moving the toner image out of direct alignment with the cleaner brush; transferring the toner image from the surface onto a substrate; fusing the toner image on the substrate; measuring the entire width extending in the process direction of the cleaned areas; and converting the measurement of the width for diagnostic analysis and process control.
