Ricoh V-C3 D081 Field Service Manual page 553

SC420 to SC423 Vd cannot be adjusted to the target voltage for a drum.
The potential sensor detects that Vpl is not ±10V of the target Vpl after exposure
SC424 to SC427
of the ID sensor patterns.
SC432 to SC435 The residual voltage on a drum is greater than -200V.
TD Sensor Output Calibration
An abnormal condition is detected when output of one of the TD sensors fails to
SC360 to SC367
fall within the range of 0.5V to 4.5V.
Process Control Gamma Correction
The development gamma for black, magenta, cyan, or yellow is not within range
SC410 to SC413
(0.3 to 6.0).
The development start voltage (Vk) for black, magenta, cyan, or yellow PCU is
SC414 to SC417
not within range (±150V)
Process Control Self-Check: SP3821
After the process control self-check is executed manually with SP3820, you can execute SP3821 to check
the results of the self-check. The possible error codes are listed in the "Displayed Code" column in the table
below.
When you do SP3821, the normal display (no errors) will look like this:
10101010
Reading from left to right each "10" represents a color: K, M, C, Y.
If a problem occurs, the code will appear in the column for the color PCU where the error has occurred.
For example, If a Vdhome error (Code 15) (see table below) occurs in the M PCU, the display will look
like this:
10151010
Or if an ID sensor error (Code 21) (see table below) occurs in the Y PCU:
10101021
"99" displays while SP3821 executes.
