A Consideration about Oscillation Mechanism of a Cleaning Blade
Abstract:A mechanism of a cleaning blade squeaking due to the friction between the photoreceptor drum and the blade in a copy machine is presented in this paper. Although this problem has been known for many years, the details of oscillation mechanism are not clarified, so we have not found out the fundamental solution yet. Here, in order to clarify this oscillation mechanism, we took notice of the feature of the oscillation that the frequency changed discretely with a normal force of the blade. In other words, we found out that the oscillation is caused by couple of immanent modes in the cleaning blade, and it was dependent on the friction force which mode became unstable coupling. As a result, we confirmed that the discrete change of oscillation frequency was explained by the unstable coupled modes of the cleaning blade.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
