    The data is indeed missing in the void cross feed. If you notice the sheet on the bottom that void has actually moved a little more to the right of the page. The entire image is there with the exception of that void which may happen once a week or once a month.

        Ok, let's start with what it's not:
        It's not primary charge, or anything to do with charge or drum ground. Any charge loss would be indicated by black areas, not voids.
        It's not a drum drive or registration drive problem. The image is correctly registered on the paper (if not all there).
        It's not a charge cleaner issue, which would be in the feed direction.
        Hey, what if one of your LTR feed units was overdriving and making a Z-fold, imaging, then opening the Z-fold before fusing ... nope, that doesn't work. It would shift your trail edge registration.

        It's unlikely to be be developer drive or transfer charge loss. It would happen more frequently, have varying proportions, and not have crisp edges or clean voids. You'd also see toner density symptoms like low developer density codes or add toner indications.

        This leaves the laser unit, image processing board(s), and HDD.

        Does that narrow it down a little? =^..^=
        If you'd like a serious answer to your request:
        1) demonstrate that you've read the manual
        2) demonstrate that you made some attempt to fix it.
        3) if you're going to ask about jams include the jam code.
        4) if you're going to ask about an error code include the error code.
        5) You are the person onsite. Only you can make observations.
