1.Model Name: AR-5132

2.General: <1> There had been problems of abnormal noise in the transport DV guide section

which occurred during copy paper feeding operations. As a measure to alleviate these problems, the diameter of the transport roller was changed from ø18 to ø18.5. This change was carried out as a measure to decrease the abnormal noise.

<2> A change has been carried out in the load of the spring of the PPD1 actuator.

The load has been changed from 10g to 11g. This change has been carried out as a measure to stabilize the return of the PPD1 actuator.

when copies were delivered from the ADU during double-side copy mode operations. As a measure to alleviate this problem, the measure described below has been carried out.

3.Description: A change in the thickness of the abnormal noise prevention sheet which is attached to

the U-turn paper guide has been carried out. The thickness of the abnormal noise prevention sheet has been changed from t= 0.25 to t=0.125.
