Title: Paul H. Tam and His Printer and Copier Innovations.

Introduction

Paul H. Tam is an inventor associated with Rochester, New York. His patent work addresses the precise positioning and adjustment of optical writers and photoconductive drum assemblies in electrophotographic printers and copiers. He holds 3 patents.

Latest Patents

Tam’s patent, “Pin Mount for Optical Writer/Image-Recording Element in a Document Printer/Copier,” describes a mounting arrangement in which the drum assembly and optical writer share mechanical positioning points. Using the drum’s mounting pins to position the optical writer helps reduce tolerance stacking and allows either subsystem to be removed without shifting the other. The arrangement also eliminates the need to retract the optical writer when removing the drum, potentially reducing cost and improving reliability.

In “Skew Adjustment for Optical Writer in a Document Printer/Copier,” Tam describes an optical writer mounted so its skew can be adjusted relative to the photoconductive drum. The adjustment helps align the projected image line with the drum’s surface, while the writer and drum continue to use shared mechanical fiducials for positioning.

Career Highlights

Tam’s listed company affiliations include Nexpress Solutions, Inc. and Eastman Kodak Company. His patent work reflects a focus on mechanical alignment, serviceability, and image positioning in printer and copier systems.

Collaborations

Named coworkers include Jeffrey R. Ulreich and Donald Calvin Buch. The patent descriptions emphasize coordinated positioning of printer components, though the supplied information does not specify each coworker’s role.

Conclusion

Paul H. Tam’s inventions address practical challenges in printer and copier design by improving component alignment, simplifying maintenance, and enabling precise image adjustment.
