The method comprises retracting the retractable cleaner from the surface, having movement, while developing a toner image on it, having a first measurable length, engaging the retractable cleaner with the surface to remove a first predetermined measurable portion of the first length of toner image, retracting the cleaner and maintaining it retracted over a distance equivalent to a second predetermined measurable portion of the first measurable length of the toner image remaining on the surface and re-engaging the retractable cleaner to remove the particles remaining on the surface from a third measurable portion of the first measurable length after passing the distance equivalent to the second predetermined measurable portion. The method further comprises measuring a second length of the toner image remaining on the surface, the second measurable length comprising the second predetermined measurable portion plus a length of the toner image remaining on the surface that occurs as the retractable cleaner retracts away from and engages with the surface. |
