    Xerox 4112 Dirty on the duplex side

    Hi guyz,

    When i print 2 sided, the back side appears to have an accumulation of dirt. At first few 10+ prints, its not yet so visible, just some little negligible spots... then as more prints are done, its getting dirtier and getting more visible. Its happening near the end of the back page, 3/4 from the trailing edge.

    Anybody can guide me where else to check? Im not so familiar with this model. I have cleaned already most of the part where duplex is happening. Print will be clean on the first few then start to become dirty again after several more page.

    Thank you
