    Bizhub 450i Blank prints when original runs through ADF

    I have a KM Bizhub that will print off the glass but when the original runs through the ADF the print is blank. Rear of page prints when duplexing. The scanner board and ADF board has been changed. P8 firmware. What would cause this?

    Does the scanner LED lights where this happen?

        Only thing left is the CIS (contact image sensor)

          Are there any error codes in the history? Rather than a fault in the CIS itself (which should cause the problem from the flatbed as well) I'd think it might be out of position.

            These codes were in the history.

            D391

            9401

            D301

            Upon running diagnostic and recovery tool I got a SSD NG. Storage board was replaced
