Chapter 99-29F-9-57When you have completed the foregoing series of steps, be sure to putback the pin in its initial location before putting the fixing upper unitback in the machine.15) Release the 2 hooks [1] used to hold the bearings on both ends of thefixing roller in place; then, detach the fixing roller assembly [2].F-9-58If you are replacing only the gear, bushing, or bearing (i.e., not replacingthe fixing roller), be sure to wrap paper around the roller before startingthe work. This is to prevent damage to the surface of the roller in theevent that the bearing falls on it during the work.If you need put aside the fixing roller somewhere for a while, be sure toput it on paper.F-9-5916) Remove the 2 C-rings [1], 2 gears [2], and 2 bearings [4] from thefixing roller assembly.F-9-60As wear grows, the surface of the fixing roller tends to becomediscolored. This phenomenon, however, will not affect the performanceof the roller. The color of the roller varies depending on its manufacture,but the performance of the roller is the same.9.5.4.2 Points to Note When Mounting the Fixing Roller0009-4871- A new fixing roller comes wrapped in paper. Be sure NOT to removethe paper until you have placed the fixing roller in its correct locationin the fixing upper unit and have fixed the bearings in place on bothits ends using hooks, thus avoiding damage possibly occurring if anyof the bearings falls on the roller.- Pay attention to the orientation of the bearing [1] and the bushing [2].Be sure that the side of the bearing with a groove is toward the inside,and the collar of the bushing faces outside. Also, the rear and frontfixing gears are different from each other; be sure to mount the gear[3] (w/ larger protrusion) is at the rear while the other gear [4] (w/smaller protrusion) is at the front.F-9-61- When attaching the C-ring [1], be sure to fit the 3 protrusions [2] of thering properly into the 3 grooves [3] of the fixing roller.[1] [2][3][2][1][1][1] [2][3][4][1][2][3][4][1] [2][3] [4]
