    I know I'm getting off topic, but I must have swapped and /or replaced a handful+ of CCD's with no error codes, just distortion on the AR BC /ARC series back in the day.

    Re: Sharp Mx-3100 copies distorted

    Thanks for the info. I hadnt even thought of using ledger to get a broader perspective from the flatbed. I will be back there in Tuesday, will post follow up if there is a resolution. This one is a real pain, between the customer being on a vpn and the whole shutting it down randomly deal.

    Looking at your examples, the printout AND copy is skewed and the margins on trail edge is very wide. I would ensure that your K laser is aligned; all the color align from K. If black is jacked, the rest are whacked...lol, that just came to me.
    ADF could also be skewed and a copy from platen would determine that.
    The other thing I notice about your scanned examples is the issue does not go edge to edge, it is within the range of optics. Being that prints are good, the issue is most likely somewhere in the optics.
    Run your shading and SIT chart setups in SIM 63 after you get the laser lined up. On this older model, I think it is SIM 61 for LSU alignment....


    Failing to plan is planning to fail!!!

    Re: Sharp Mx-3100 copies distorted

    That kind of struck me with a thought, might be dumb. I replaced the entire adf the other day. Old one had feeding issues. Is there a way that could have skewed the spf in such a way as to produce that? Part of me is second guessing that now whether or not I tested both spf copies and flatbed copies or not. Or if the difference between a mx-2600 and a mx-3100 is enough, if memory serves the part number was the same for both. *facedesk* I'm goin back to bed.

    Re: Sharp Mx-3100 copies distorted

    You might get skew or blurs is the DF is significantly too high at the front or back of the slit glass side. Or if the right hinge is significantly out of adjustment (not sitting squarely on the top of the MFP). That's the only way I see the DF having anything to do with it. =^..^=

    Ledger scan mx3100.pdf Dual scans of a ledger printout
    Original scans BW.pdf Scans of the cleanest copy of the text doc I could get from the optics cleaning and a copy of the LSU calibration sheet.

    Mildly confusing I know but this was in an effort to display the problem. Since it occurs only in the Black system. Cleaning the optics seems to have helped but didn't clear it completely. Cleaning the lsu didnt change anything at all as far as distortions go. The cleaning rod in the fuser has some stuff attached but I doubt that it has enough to cause all this. It will get swapped on Thursday either way since they're cheap enough that I have others on hand for that sort of swap tomfoolery.

    Re: Sharp Mx-3100 copies distorted

    Just to clarify:
    The first document was a scan on the problem machine of a ledger original through the DF? Or off the glass?
    The second document is a scan on a different machine of the originals used for testing?

    I'm confused. =^..^=

    I too am confused, but back a few posts ago. I assumed these scan were taken from the platen glass and not the adf. Is the problem through the adf or from the glass?

    Re: Sharp Mx-3100 copies distorted

    From both the flatbed or through the spf it comes out distorted. Cleaning the mirrors seems to have helped but it's still distorted. Tried making a ledger copy to see if there was a difference since up until then letter was all I had tried. Thinking that maybe in a new set of dimensions there would be difference in distortions or something. This is the most work I've done to date on the flatbed optics so I'm guessing I'm still missing something somewhere.
