Sc350 appeared on 2035 after completing copies operations

[akbareshghi]

Sc350 is generated when the operation of coping is finished regardless of the number of copies
I go to service mode and I performed 3001-02 (ID Sensor Initialization) but before appearing the message of complete , the SC350 error code is generated.
If I copy the originals with this situation , do it create problem for laser.
My current setting of 3001-01= ID Sensor PWM Setting= 255
My reading of 3103 are the following :
Vsg (Drum Surface Output)= 1.31 v
Vsp (Pattern Output)=0
Vpdp (Immediate Post-Pattern Output)=0
Vsm/Vsg (Immediate Grayscale Post-Pattern Output)=0
My guessed causes of this error:
1- High voltage power supply board
2- My wrong setting of TD sensor
Thank you for one permanent solution

Background on copies there? Safety glass laser clean?

I removed the pcu unit and cleaned from bottom the ID sensor with brush and cotton
then i reinserted pcu unit and go to service manual and perform 3001
then sc350 does not appeared and my problem is solved
