Introduction

Frank A. Shuster is a notable inventor based in Rochester, NY (US), recognized for his contributions to the field of electrophotographic printing. With a total of nine patents to his name, Shuster has made significant advancements in toner transfer techniques that enhance the efficiency and quality of printing processes.

Latest Patents

One of Shuster's latest patents is the toner transfer technique, which involves a module included in an electrophotographic printer. This innovation allows for the adjustment of transfer current to compensate for ambient variations of toner charge-to-mass ratio (q/m). The method utilizes a predetermined functional relationship between transfer current and a control voltage parameter, derived from voltage measurements related to toner control patches on a photoconductive image-recording member. The co-optimization of three experimentally determined parameters ensures efficient toner image transfer while minimizing back-transfer of toner away from the receiver member.

Another significant patent involves a time-varying transfer station current in an electrostatographic machine. This machine features a transfer station that includes a toner image carrier and a transfer member for the electrostatic transfer of toner to a receiver sheet. The programmable power supply controls the transfer station current, which is successively altered between predetermined magnitudes to suppress wrap during the transfer process.
