Surface Resistivity; Paper Specifications; Uncoated Paper - Ricoh MP C6502 series Operation Manual

1. Characteristics and Conditions of Paper

Surface Resistivity

Represents the electrical resistance on the paper's surface.
It may affect the quality of printing and the movement of paper in the machine.
For the values for the surface resistivity of paper, see page 8 "Paper Specifications".
