  1. Electrophotographic Development and Transfer Station P09503 ISO Compliant Safety Signs The electrophotographic process requires extremely high voltages and quick translational movements to transfer electric charge and toner to a substrate. The implementation of higher visibility warnings signs will alert system users to hazards such as high voltage and pinch points. The improved visibility warning signs will be compliant with the ISO and will encompass the type of hazard along with safety information in word and symbolic form. Project Objective The purpose of project P09503 is to make an existing Electrophotographic Development and Transfer Station functional and to improve the usability, safety and sensing abilities. Electrophotography (EP), seen below, is the base technology used in most modern day copiers and printers. The functional station will be used for research in the RIT PRISM Laboratory. LED Exposure System An LED array replaced the current incandescent projector bulb to expose the photoconductive material. The advantages an LED array is decreased power consumption, longer system lifetime, minimal potential to overheat, and inexpensive to replace if needed. The LEDs would also prove to be a more reliable and versatile light source. LED System LED Array Uniformity EP Process Electrostatic Voltage Measurement System Monitoring the potential on the photoconductor after charging and exposure will help to understand the dark decay and charge uniformity of the photoconductor. Mounts were machined in order to hold the electrostatic probes within range of reading the potential of the photoconductor. The probe was connected to the LabView interface to centralize process data. Photoconductor Imaging System Imaging the photoconductor following application of toner will increase the flexibility of the user to monitor and understand the electrophotographic process in conjunction with the electrostatic voltage measurements. A mount was machined to hold a Nikon DLR camera. The camera is controlled and images are viewable via LabView. Paper Delivery System The existing system required manually catching the paper after application of toner from the transfer drum. Risks of this operation include marred image quality due to poor handing as well as high voltage and pinch point hazards at the pneumatically operated transfer drum. The solution was to create a system to catch the paper without user intervention. User Interface and Camera Mount Electrostatic Probe Mount Paper Delivery System Electrophotographic Process Control and Automation Critical to system functionality, all devices were connected to a PC via a Data Acquisition Device and controlled by LabView. LabView was then programmed to automate the electrophotographic process. LabView provides the user the option for full automation or manual operation for advanced users.
