  • Patent number: 8910941
    Abstract: A roller nip assembly has a drive axle (with driver rollers) and a drive unit connected to a first end of the drive axle. The drive unit rotates the drive axle. In addition, a slotted mount is connected to a second end of the drive axle (opposite the first end). Additionally, an idler frame (with idler rollers) is positioned adjacent the drive axle. Further, a bias member is connected to the drive axle. The bias member moves the drive axle in the slotted mount to bias the drive rollers toward the idler rollers. The idler frame also includes a pivot structure. The bias member causes the drive axle to pivot. The pivot structure pivots the idler frame to compensate for the pivoting motion of the drive axle and to maintain pressure between the idler rollers and the drive rollers as the drive axle pivots.

  • Publication number: 20140339763
    Abstract: A fixing device includes a sheet detecting mechanism configured to detect a sheet. The sheet detecting mechanism includes an actuator, a link member, and a detecting part. The actuator swings by being pushed by the sheet. The link member swings in conjunction with the swing of the actuator. The detecting part detects the swing of the link member. When a shift of a position of the actuator with respect to the detecting part is caused, the actuator slides with respect to the link member to absorb the shift.
