it does not stop feeding toner, since the tcr reading is very low 2

change
imaging unit M(x2)
PRCB
PHRYB

The lines of the connector of the unit to the PHRYB give continuity...
I even put unit C in position M, exchanging the chips... and I have the same result, the TCR reading M 2% (unit C)

I think the problem is the T/C ratio detection, because this value can be affected?

Today I will try the initialization clear all data and update the firmware.
I run out of ideas

I don't think you put new M IUs, did you?

No creo que hayas puesto nuevos M IU, ¿verdad?

no, probe 2, which borrows from equipment currently working, with normal TRC measurements (In fact, I had to cover the toner input because if I didn't recharge them with toner)

Using used IUs(developing units) you need new TCR chip to calibrate machine or it gonna be hit or miss.

Replace the magenta imaging & developer units with new ones.

You can create more problems swapping used units about.

At one time was servicing around 50 of the C654 / C754e's and swapped Image units many times from one machine to another without issues. I think you may have something else going on?
