摘要：Printer ( 1 ) feeds paper or other media sheets ( 5 ) to pinch rollers ( 9 a, 9 b), which further feed the sheets into an imaging station ( 7 ). Pressure rollers ( 9 b) are held by plate 22 which is biased by a spring ( 33 ) and pivots on extensions ( 37 a , 37 ) to moves pressure rollers ( 9 b) into nip relationship with nip roller ( 9 a). To evenly distribute the forces across pressure rollers ( 9 b), plate 22 is weakened by depressed lines ( 27 a, 27 b) located between the spring and the pressure rollers ( 9 b).
