Well back to the drawing board. Swapped out the dev unit, same result. Changed 1st primary same result. Stopped machine mid test sheet (53) at 255 k only. Image light. Density on the tcr was in spec at 130. I'll get new dev mix tomorrow and try again. It can't be any of the hv's units as every other colour is fine. This is completely odd. See printouts with every new.

How did you ever make out here>?
I have two C6501s and have had this before with a weak drum, not sure what caused it but swapping drums, yellow and black usually get me though to the next cycle.
I am still battling this issue on a c1070. Luckily for me it is in our printshop out front of our office. We have 2 C1070s. I have swapped The entire carriage, drums, charges, etc. i swapped the carriage itself. Transfer belt, Color registration assembly, PRCB. No luck, the same machine still codes. It is intermittent but it will code multiple times in a row once it happens. Reseat some things and magically its gone.
I am looking to replace the wiring from the PRCB to the connector that the carriage meets. Not sure what else to do.
Cut those zip ties 1st...
is the faulty machine near the doors? lower humidity or right under the HVAC vents?
would swap drum motors next...
on the C6501 we had to replace the DV drive unit - at 5million. Not sure where your meter is at on the faulty one....
