Abstract
A fusing assembly includes a fuser member, such as a rotatable fuser roll which, during operation, contacts a sheet of print media to fuse a marking material to the sheet. A stripping apparatus applies gas to the sheet to assist in detaching the sheet from the fuser roll. The stripping apparatus includes a fluid pathway which connects an associated source of pressurized gas with at least one orifice adjacent the fuser roll. A pressure sensor senses a pressure of the gas in the fluid pathway intermediate the source and the at least one orifice during operation of the fuser roll.
