The difference between data A and data B is 0±20.If the difference is outside the specification, replacethe environment sensor.11) Press the Reset key, and turn off the power switch.12) Remove the sensor for the environment sensorfrom the environment measurement PCB, andinsert the environment sensor.13) Install all covers.The sensor for the environment sensor (TKN0456) is adjusted with high precision at the factory.Keep it in a sealed case with a drying agent.2.7.10 Checking the HighVoltage Control System 0002-0468CLC5100 / CLC4000a. OutlineIf an image fault occurs, you must first determinewhether the cause is the latent static formation blockwhich includes the photosensitive drum and thepotential control system or the developing/ transfersystem.The machine's highvoltage is controlled to a specificlevel using the environment sensor and the potentialsensor.T-2-7b. Target Contrast PotentialThe primary grid bias or the developing bias controlmechanism may be checked by canceling the autosetting mechanism by the environment sensor fortarget contrast potential.1) Select 'VCONT' of 'ADJMISC' under 'ADJUST' inservice mode.2) Select an appropriate value from the target contrastvoltage levels in the following table, and enter it.T-2-83) Execute 'FUNC > EPC' in service mode.Sensor Environment sensorEnvironmentsensorPrimary grid biasTransfer blade biasSeparation charging biasPotentialsensorPrimary grid biasDeveloping biasY M C K0 Auto Auto Auto Auto1 390.00 365.00 370.00 420.002 390.00 365.00 370.00 420.003 390.00 365.00 370.00 420.004 370.00 345.00 355.00 410.005 340.00 325.00 335.00 390.006 310.00 295.00 315.00 380.007 295.00 275.00 290.00 370.008 245.00 225.00 225.00 330.00
