konica minolta c450 is only printing in black, no color. Came on suddenly. All color tests will just print black. All color printing ceased at the same time.
Any ideas?

When you say printing black on the colour test print, do you mean it is only the black portion of the print that is printing or that it is printing the entire test print in black? It could be the transfer pressure/retraction as the black IU is always in contact with the belt but the colours only engage when needed. As a basic step, these machines seem to do strange things occasionally when it comes to colour but a good turn off/on usually fixes them.

It's only printing the black portion of the test. I have several color tests I run some of which are files of my own. When they are ran, only the black areas of the tests are printed - the other areas that are to be in color do not print.
The reason I find this strange is that is was working fine according to the printed copies I saw just hours before.
I would check transfer belt assy, see if the color rollers are moving properly
And that would happen all at once with all three CMY iu's?
Yes, because I believe that the CMYs are working, the belt just isn't contacting them. iirc, the belt is always set for black, but needs to come up to position for any (and all) color copying.

replaced the transfer belt - no change
I am getting a p6, p7 and p8 error code - which are cmy imaging unit failures but can not find out why
