Abstract

Disclosed is the process for continuous testing during preparation of the charge-dissipation grounding stripe on organic photoconductor belts. The operations insure 100-percent tested grounding for the photoconductor grounding stripe, and, further, insures manufactured good grounding stripe belts. The mechanical scribing for striping and the test circuit for 100-percent verification of grounding are described.

Conductive Ground Stripe Performance Insurance for Organic Photo Conductor Belt Manufacture

Disclosed is the process for continuous testing during preparation of the charge-dissipation grounding stripe on organic photoconductor belts. The operations insure 100-percent tested grounding for the photoconductor grounding stripe, and, further, insures manufactured good grounding stripe belts. The mechanical scribing for striping and the test circuit for 100-percent verification of grounding are described.

A multi-layered organic photoconductor is slit to final width after coating. The barrier layer, charge-generation layer (CG) and charge-transport layer (CT) are coated on the aluminum, but not to the edge of the aluminized polyester. The aluminum layer is exposed on the edges. Preparation of the coated photoconductor layers for application of ink that produces the grounding stripe is by scribing at the time of slitting to final dimension. Conductivity detection consists of a brush on the aluminum at the edge and connected to a voltmeter. The circuit is completed to the two carbide scribes which scratch two parallel furrows a fixed distance from the slit edge, and makes contact to the aluminum layer through the CT, CG and barrier. The scribes are set to always scratch to the aluminum (regardless of MYLAR* thickness variations). Scribing is to and/or through the aluminum layer. Tracking and control is achieved with a servo. A stop keeps the scribes from scratching too...
