Reversion 4.0
Corrective Action 3
Corrective Action
1. Procon Area
• ADC (Automatic Density Control) Fail (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Check the connections to the ADC Sensor.
• Check the operation and condition of the Shutter.
• If OK, replace the ADC/MOB/Temp/Humidity sensor bar. (PL 11.1)
Corrective Action 4
Corrective Action
1. Procon Area
• TC (Toner Concentration) Target vs. Measured more than 30 bits off.
2. Prints And What To Look At.
• internal test pattern 53, Low, mid and high patches.
3. Corrective Action
• Ensure that toner cartridges are not empty.
• Perform Adjust Toner Density.
• If the problem is in high density patches, then troubleshoot IOT problems.
• If the problem is only in low and mid density patches then perform TRC Adjustment
and adjust low, mid and high starting with low density.
NOTE: Center value is “0”. Range is -128 to 127
Corrective Action 5
Corrective Action
1. Procon Area
• TC (Toner Concentration) Patch Fail (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Ensure that toner cartridges are not empty.
• Perform Adjust Toner Density.
• If the problem is in high density patches, then troubleshoot IOT problems.
• Observe Developer Mag Brush for defects or missing Mag Brush in all colors.
Corrective Action 6
Corrective Action
1. Procon Area
• Temp (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Failure occurs below 32 degrees F (0 degrees C) or above 140 degrees F (60
degrees C).
• Check connections to the Temperature Sensor.
• If the connections are good and the temperature is within spec then replace the
ADC/MOB/Temp/Humidity Sensor Bar.
Corrective Action 7
Corrective Action
1. Procon Area
• Humidity (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Failure occurs when the humidity is at 0% or above 105%.
• Check connections to the Humidity Sensor.
• If the connections are good and the humidity is within spec then replace the ADC/
MOB/Temp/Humidity Sensor Bar.
Corrective Action 8
Corrective Action
1. Procon Area
• ADC Patch Fail (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Check ADC Target vs. Measured, ADC Sensor fail, ADC shutter fail and ADC mini
setup fail.
• Check connections to the ADC Sensor.
• Check the operation and condition of the shutter and Clean if necessary.
• Replace the ADC/MOB/Temp/Humidity Sensor Bar. (PL 11.1)
Corrective Action 9
Corrective Action
1. Procon Area
• ADC Mini Setup Fail (NG).
2. Prints And What To Look At.
• (Nothing to look at)
3. Corrective Action
• Check connections to the ADC Sensor.
• Check the operation and condition of the shutter and Clean if necessary.
• Replace the ADC/MOB/Temp/Humidity Sensor Bar. (PL 11.1)
• Check for failed components:
– HVPS (PL 11.1)
– Developer Housing(s) (PL 5.2) or bad Developer Bias.
– MCU PWB (PL 11.1)
– Photoreceptor Machine Consumables
