FIXING ASSEMBLY

Subject:

Measures against noise, E014, and faulty fixing caused by coming off of fixing roller

Detail:

<Symptom>
The fixing roller comes off, leading to noise, E014, and faulty fixing.
<Cause>
Because the fixing spacer [2] does not rotate while the fixing roller [3] is rotating, the retaining ring [1] becomes
detached due to frictional resistance with the fixing spacer, and the fixing roller comes off as a result.

<Factory Measures>
A projection (P-2 [1]) is added to the fixing spacer. When attaching the fixing spacer, fit the projection in a
groove (P-3 [2]) of the fixing roller shaft so that the fixing spacer will rotate together with the fixing roller and
frictional resistance between the fixing spacer and the retaining ring will be eliminated. Therefore, the retaining
ring is prevented from becoming detached.
