In this case you have any problem with the imaging unit. replace one by one to identify the defective unit.

in level history mode tcr level in all of imaging units ( CMYK ) is 0.00 on stabilization and ready to copy.
if one of imaging units have a fault or disconnected on tcr sensor it displays 13 - 15 on level history not 0.00 ?!!!

I would look at a HVT, or overall power supply issue, especially with all 4 mis-reporting. Emujo

i don't think that problem is on HVT because machine have not any P warning on stabilizing and printing quality but power supply can makes this problem on miss reporting from MFP.
i check it power supply board soon.
thanks emujo.
