    Grey Scale is usually referred to print through a color unit..
    not sure what you are trying since yours is a B&W only

    They likely mean it only prints in full density black or white with no variation in density. A BW machine can print in greyscale by varying in the density of the toner applied to the page.

    the OP (imho) didn't really make clear his issue.

    but he has wasted time and $$$ by not diagnosing properly and just shotgunning his repair approach

    AFAIK, the driver does not have a grayscale option to print. Did you check if you were using the correct driver? How bout changing the settings (edge smoothing, toner saving, process as bitmap)?
    Aye! Cut the crap

    I think I have not explained myself well, when I print a photo on the mp7500, the print has no grays, no details, very loaded with toner, practically all black, an example:

    Photo ok, print with other mp7500: photo-ok — imgbb.com
    Photo no ok: photo-no-ok — imgbb.com

    This happens printing and copying

    I have changed development unit, charge unit, image unit, transfer unit, boards, etc, of the other machine, and the quality doesn't change, any ideas?

    Is it the correct driver? I doubt it.

    If it's doing it with prints and copies it could possibly just be over toned? I would remove the toner and run some sky copies to get the density down to see if it makes a difference.

    I did have a machine do it only when printing PDF's before and that turned out to be the driver as others have already suggested

    What about copies? If copies are ok then you must check driver program and make arangements . Something about dithering or .....
    Is toner genuin?
