Question about Xerox DocuColor 12 Printer

1 Answer

DC12 - Yellow Banding (top to bottom)

Hi, DC12 was working fine and then mid-run had image quality problems. In short after some messing around I've been able to determine that the problem is related to the yellow toner system. If I print a color in any color mode apart from black, the print has yellow bands running top to bottom every one and a half inches. From the waste toner bottle and from inspecting the drum it seems like there's excessive yellow toner being deposited. I've replaced the drum with no change of symptoms, I'm now thinking it could be something to do with the rotatary unit (yellow) or too much yellow toner being taken from the cartridge somehow. I'd really appreciate it someone could give a few pointers. Unfortunately I don't have local xerox support otherwise I'd have called them in by now. If any of you have had or heard of a simialr problem, I'd sure like to hear from you.
Regards Carl Grainger.

    Finally managed to get a Xerox guy in - 15 mins later all was fixed. A small plastic clip on the end of the yellow toner dispenser had broken. Not an uncommon problem he said. Very quick and cheap to fix.

There is a software patch on the Xerox.com site.
Once there click Support and Drivers.
Once there in the search box enter dc 12
Once to the Support area. Type in Yellow in the search box. That should direct you to the patches.
I hope this helps.

    I would have not guessed that based on your issue.
    Thanks for the feedback.
    Glad you have it resolved.

Sony 43 inch rear projection tv, I have lined up the convergence but still seeing red and green around edge of the tv on the images, seems fine in the middle of the screen though.


Always start at the vary center of the screen with Green. Position Red over Green, then Blue over what now will look yellow. If all is perfect except the outside, you will need to adjust "Mid-Size" until the middle is just as far off as the outside lines. Then adjust the main "Size" adustments to match. Go very slow or you can make a mess of it.

Image will not wrap correctly in vanishing point


Hi again,
Ok, I finally got it licked and why you're having the problems and it's fairly simple. It's all based on 2 things but most of all, the order in which you create your planes or grids.

Because the main part of the image is on the front face that is what you want as your Parent face so get that as accurate as you can to start off with. Hold the 'x' key to temp zoom in and get the position as correct as you can.
Once you've created you're primary ctrl-click(cmd-click on mac) the mid top point and pull it out then the same for the mid left point.
Now if it still has the problem when you paste in the image and drag it onto the primary face then undo the paste. We need to adjust the secondary planes. Select the top plane and in the angle parameter (which should show 270°) change it to 269°. Then change the left planes angle to 89°. Try it now and it should work fine. Then put it back to 270° and 90° again.

Let me know how you get on.

All the best
