SC342: TD sensor adjustment error 2
During the TD sensor auto adjustment, the TD sensor output voltage (Vt) does
not come in the target range (2.5 ± 0.1V) within 20 seconds.
Note:
When this error occurs, the indication of SP2-906-1 is 0.00V.
-Possible cause-
•
TD sensor defective
•
Poor connection between the TD sensor and the I/O board.
•
I/O board defective
Note:
In this error condition, the toner supply is controlled using pixel count and Vsp/Vsg.
You might need to replace the TD sensor. I doubt it is the I/O board. If you replace it, then make sure that the toner supply setting is set back from oixel count.
