0114/0119 jam codes/abnormal sound due to the fixing assembly
86T gear with missing teeth
[Symptom]
0114 jam, 0119 jam or abnormal sound from the fixing assembly may occur in the machine earlier than the following
countermeasure cut-in serial numbers in factory.
- 0114 JAM : Primary Fixing Inner Delivery Sensor 1 (PS305) Delay jam
- 0119 JAM : Secondary Fixing Inner Delivery Sensor 1 (PS313) Delay jam
[Cause]
The 86T gear [1] on the rear side of fixing assembly has not enough strength due to short heat treating time when the gear is
created. Therefore missing teeth occurs and that results in the foregoing symptom.
[Reference] Photo [A] shows the 86T with missing tooth.
If debris from the teeth of the gear gets into meshing of the gear, a load is applied to and damages [a] the hemming of the
separation drive mount 2 [1], and this may result in the above mentioned symptom.
Also, the separation drive mount 1 may break.
[Reference] The separation drive mount 2 [1] and the separation drive mount 1 are attached to the primary fixing assembly only.
The separation drive mount 1 is the bond-locked sheet metal attached to the back of the separation drive mount 2.
