C2456, C4521
The machine was recently PM'ed, C:509K, BW:26K
It's a bit early for the magenta developer but it's the only logical conclusion I could come to. All the toner sensors read between 29.7K and 30.0K, magenta marginally higher than the others. I swapped TCRS4 with TCRS2 and got the same results. The magenta developing motor runs along with the others.
I thoroughly cleaned the color registration sensors twice. Naturally there was a toner dustcloud to clean up, but none inside the sensor housings. The registration assembly is fitting tightly to the transfer belt frame.
I have gotten it to run for short periods of time, mostly just dumb luck. I got a Management List loaded with both codes, nothing else. If it matters, this enduser has printed exclusively BW for the last month.
Did I miss something obvious? =^..^=
