TASKalfa 250
Check point for C710X in Saturn Taskalfa 500ci series
We can see the toner sensor value by U155.
If toner sensor value becomes lower than 100 even after a few days from changing the developer units.
I think there are two reasons why this problem occurs.
●The one is that the relay board which is shown by red circle in the following picture (A) might be broken by repeated detaching of DV. ->Please change the relay board.
●The other is that the pinched wire which is shown by blue circle in the following picture
(B). ->Please check if the wire is pinched between the plastic parts and metal plate.
