8. Run Pro Con “Off” and compare the two prints.
Corrective Action 1
Corrective Action
1. Procon Area
• ADC (Automatic Density Control) 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
• 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 2
Corrective Action
1. Procon Area
• ADC (Automatic Density Control) Shutter Open Fail (NG) or ADC Shutter Close 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)
