    Three things that can usually cause the scan to fail; dirty optics, dirty ID sensor or depleted development unit. You may need to replace the development unit.

    I've found solutions guys.
    one of the gears at the developer unit is broken, also the cover too.
    I replaced all and everything seems to work fine now. Attached are the broken accessories.
    Thanks for the contributions, deeply grateful.

    For example a job that has Red in it only Magenta appears. I have tried all I could know changing developer, opc drum, OEM toner, it seems not to work.

    Does anyone knows what the issue is??
    try replacing drum and developer as the drum surface is too weak to originate pixels on it, the test pattern yield more charging than copy.

    I didn't buy complete unit. OEM Developer only bought from Amazon, I had to replace other parts from damaged developer unit.
