摘要： A media stripper mechanism includes a shaft, one or more first stripping members, and one or more second stripping members. The shaft extends in an axial direction thereof parallel to a rotational axis of the rotary member. Each of the one or more first stripping members is a pneumatic nozzle that has a proximal end thereof supported on the shaft, and a distal, free end opposite the proximal end thereof pointing toward the rotary member to direct compressed gas toward the nip along the rotary member for stripping the recording medium from the rotary member. Each of the one or more second stripping members is a non-contact finger that has a proximal end thereof supported on the shaft, and a distal, free end opposite the proximal end thereof pointing toward the rotary member to assist in stripping the recording medium from the rotary member without contacting the rotary member.
