Abstract:
1. An apparatus comprising: a sheet path; a first nip at a first location of said sheet path; a second nip at a second location of said sheet path; and a speed control circuit controlling sheet feeding speeds of said first nip and said second nip, said first nip feeding a sheet of media to said second nip along said sheet path, said speed control circuit maintaining said first nip and said second nip at a first sheet feeding speed when a leading edge of said sheet of media is between said first nip and said second nip, said speed control circuit creating an amount of buckle in said sheet of media by increasing a sheet feeding speed of said first nip to a second sheet feeding speed while maintaining said second nip at said first sheet feeding speed during a first portion of when said sheet of media is simultaneously within said first nip and said second nip, said speed control circuit decreasing said sheet feeding speed of said first nip to said first sheet feeding speed after creating said amount of buckle in said sheet of media, said speed control circuit maintaining said first nip and said second nip at said first sheet feeding speed during a remaining portion of when said sheet of media is simultaneously within said first nip and said second nip to maintain said amount of buckle in said sheet of media during said remaining portion of when said sheet of media is simultaneously within said first nip and said second nip, and said remaining portion of when said sheet of media is simultaneously within said first nip and said second nip occurring from when said creating an amount of buckle in said sheet of media is complete until a trailing edge of said sheet of media exits said first nip.
