100
250/10 * This PWM sets the laser intensity to be shoot on OPC.
* Default 100, 95 PWM are approximately 0.254mW, 0.241mW.
95
250/10
* This value changes +0.0026mw per +1 PWM.
95
250/10
* This value is to check the normal state of HVPS,LSU.
95
250/10
* The value set on EDC manually is not applied to the real printing.
* At real printing, the value is applied by the Look-Up Table
considering the environment and life automatically.
175
255/90 * This value is the TC sensor control voltage PWM to adjust the
toner density.
175
255/90
* Default is 175. But, if the new imaging unit is installed, PWM will
175
255/90
be changed after TC Sensor Initialization.
175
255/90
* Default 175 PWM is approximately 8.15V.
* This value changes 0.01V per +1 PWM.
* This value is to check the normal state of the toner density
sensor output.
* The value set on EDC manually is not applied to the real printing.
* At real printing, the value is applied by the Look-Up Table
considering the environment and life automatically.
5
100/0
* This value is the ADC to control the toner density.
* 5 ADC (for initial toner only) is the target+0.5wt%(9.0wt%)
* The more the value increase, the more the toner density
5

250/10 * This value is the ADC to contol the toner density.
* 140 ADC(for initial toner only) is the Target -1wt% (7.5 wt%).
* The more the value decrease, the more the toner density
140

128
250/10 * This value is the ADC to control the toner density.
* In case of 128 ADC (for initial toner only), toner density is
128
250/10
8.5wt%.
128
250/10
* The more the value increase, the more the toner density
128
250/10
decrease.
* The more the value decrease, the more the toner density
increase.
* You must input the value less than lower limit.
