Does it happen if you print B&W only, like the internal config test page?

Looks like you need to replace the magenta imaging unit

it happens in every page. even if its halftone, all colors and even on counter list print. this is just a demo. i swapped the iu's too. nothing.

Seems like Magenta Developer problem .

Try to replace it .

I'm going to make an educated guess that you've lost magenta primary charge. With no magenta primary charge the drum is entirely imaged magenta with no voids.

The reason copyman asked if it happens on B&W is that the color section of the HVT are disabled during monochrome copies, so black copies should look normal. So what is the answer? Black only copies, what happens? =^..^=

You have covered the IUs, then HVT should be the culprit. Had it once on C258 with yellow, with the difference it blanketed the whole ITB not just part of it.
Just one thing puzzles me, isn't the meter count printout done with just one PC (K)?

Does the belt retract when you manually rotate the gear? Anything snapped on M 1st transfer roller? Pressing against the M drum one side only even during K only print?

I am assuming that if you stop the toner image on the belt before transfer to the page it is a complete image ?

If so the problem lies with the transfer roller and we have had this before, check the springs and the lift cams

What about PH and PH drive board? OR firmware update AS all color PH are different but board is same.
Ideally he should check 80% CMYK patch on A3 and before paper leaves registration assy. stop the machine and check the image on drum.
ITB, 2nd Transfer, fusing all are bypassed.
Its only Firmware (which I doubt), mfp board which is malfunctioning, PH drive board ( assuming same, identical pattern in all colors)
