hi guys... I am not an expert ricoh machine technician.I need your help regarding the sc 400 error on my MP-C2800..
I already cleaned the ID sensor unit & ITB. The issue is after printing/copying a document the sc 400 error appears.
So I will turn Off the machine then ON,error disappear. after printing again error appears.

The following is from TSB 010 for the MP C2051/C2551 but the procedure ans SP modes are the same.

Please follow the troubleshooting steps below to resolve an SC400 (ID Sensor Adjustment Error).
1. Check the harness of the ID sensor.
2. Clean the ID sensor with a cloth moistened with water.
NOTE: Never use alcohol, because this may damage the board.
3. Execute SP3011-001 (manual process control).
4. If the value of SP3324-003 (Vsg error counter) is NOT “0”, repeat Steps 2 and 3.
5. If the value of SP3324-003 is still NOT “0” after repeating Steps 2 and 3, check the spring for the PTR unit
contact lever. Repeat steps 3 & 4.
6. If the value of SP3324-003 is still NOT “0” replace the ID sensor. Repeat steps 3 & 4.
Notes:
1. If the black spacers are stuck to the sensor board, remove all black spacers. These black
spacers should be used when a new ID sensor board is installed.
2. Input all correction coefficients for the ID sensor with the SP modes referring to the barcode
sheet provided with the new ID sensor unit/board.
For example, input "0.98" with SP3362-013 & 016.
Always refer to the Service Manual for the complete part replacement procedure.
7. If the value of SP3324-003 is still NOT “0” replace the BCU. Repeat steps 3 & 4.
8. If the value of SP3324-003 is still NOT “0” replace the ITB unit.

If you have used alcohol or any type of solvent to clean to ID sensors it may have clouded the surface of the sensors and it will need to be replaced. If you have used a dry cloth or paper towel to clean with it can cause static build up that will immediately attract dust and/or toner.

Thank you slimslob, I will try to check it today..I guess the sensors we're damaged as I was using a contact cleaner in cleaning them.
