SC codes Group 4: Image Development - 2

SC400 D ID sensor error 1: Calibration
Before adjustment Vsg_reg<0.5 but
Vsg_reg could not be adjusted to the
target Vsg_reg = 4.0 0.2V during
process control.
Note: Vsg_reg is the voltage reading of the light reflected directly from the bare
surface of the ITB. The color ID sensor is provided with one additional receptor
to read diffuse light reflected from the colors of ID sensor patterns. The
additional receptor on the color sensor is not used to read the bare surface of
the belt. For more, see Section "6. Details".
SC410 D
ID sensor error 2: Development K
SC411 D
ID sensor error 3: Development M
SC412 D
ID sensor error 4: Development C
SC413 D
ID sensor error 5: Development Y
Development gamma for black,
magenta, cyan, or yellow is not
within range (0.3 to 6.0).
Process control halts when this
SC is issued.
SC414 D ID sensor error 6: Development start voltage K
SC415 D ID sensor error 7: Development start voltage M
SC416 D ID sensor error 8: Development start voltage C
SC417 D ID sensor error 9: Development start voltage Y
The development start voltage
in the development of the
black, magenta, cyan, or
yellow PCU is not within the
correct range ( 150V)
