colour and autocolour on MFC

What is the difference between colour copying and auto color copying. why is it that the color of the document varies with this modes. thank you.

Colour copying uses all four drum units and toner to make black and all of your colours. So if you copy a page of black text in this mode, the copier uses CMYK toner to make the image (process black).

Auto colour scans the image and determines whether the image is black and white or colour and uses the proper settings to make each copy. Often using colour copy mode your text will appear washed out since the process black is never as strong as just black toner. This is also a good way to test your optics and calibration: the closer to a true black the better the machine is running.

Make sure the optics are clean, the machine is calibrated and the image processing set to the proper setting (text, text/image, image, etc.). This will ensure the best possible copy.

Correct me if I'm wrong ... but doesn't Auto Color make a decision to print monochrome or color, based on the original content? Full Color copy does not make that decision, just uses process black (CMYK). By definition, if Auto Color selects color, the resulting copy should look exactly the same as a Full Color copy. =^..^=

I always advise the customer to use Auto Color instead of Full Color to save charges on color clicks. If they have a stack of originals and some have color on them and some are strictly b/w, if they select full color then all of the originals are counted as color prints. If they select Auto Color, the machine will determine which originals scanned have no color on them and process them as such and only increment the B\W meter. Generally I apply a user code requirement for Full Color and don't assign a code for it, that way they are forced to select Auto Color.
