      If you have changed the ITB unit with a good one, then you might have a problem with the mechanism that lifts the color transfer rollers inside the ITB.

          Looks like a Developer Unit problem...

              It seems that the revledaor is scarce in the color units but it could also be in the band that the mechanism within the band is not activated as the slimlob master teaches and bat

                  Update.
                  Thank you all for your help.
                  After changing the ITB and check that all the lifting motors working fine, I change the 3 developers with new drum and charge , now the machine working perfect.
                  Thanks again
                  God bless you all
