Instead of magnetic detection, now we have frequency detection
@Ramatzko:
In your case, maybe we get problem with the controlling by Feed Image PWB and/ or Engine PWB.
DV connected to Drum_DLP_Connect PWB --> Feed Image PWB incoming on YC17/ outgoing by YC28 --> Engine PWB incoming on YC42
If we have bad connection, maybe system won`t recognize real value and engine won`t start toner motor for adding toner.
Look for U155 at first and check wirings between the pwbs.
By the way:
Did you unplug the power plug from the wall outlet before exchange from the DV units?
Did you run ALL needed adjustments after mounting?
Check U157, U158 and U984 for correct values.
If counters and/ or SN not real, system can`t calculate need amount of toner in the right way.
