dC922 TRC Control/Toner Density Adjustment
Purpose
• Measures the Gray-Scale Patch with the ADC Sensor and creates the TRC Correction
LUT in the IOT. If the result is not within the range, the system displays the Tone up/down
result.
• Displays the density of the 2 patches for each color on the IBT Belt.
NOTE: For details on dC922 TRC Control/Toner Density Adjustment, see Adjustments
Section 4:
ADJ 9.1.6 TRC Control/Toner Density Adjustment (dC922).
dC923 PROCON PG
Purpose
• Outputs the PRCON PG (ProCon pattern), measures the ADC Patch density by the ADC
Sensor and displays the result on the PWS Screen.
• The PRCON PG should be used only for individual Adjust/Recover.
Procedure
1. Enter the Service Diagnostics Mode. Refer to Entering the Service Diagnostic Mode
using the PWS.
2. Select Adjustmen
ts on the Service Entry Screen.
3. Select the MAX Se

5. Select a Tray f
rom the Tray Drop Down List (paper: 11x17/A3 or 8.5x11/A4L) and click
Start.
• The ProCon PG is printed. (normal paper, full color, 300-lines, LUT off)
• The system generates an ADC Patch for each color and updates the NVM value
afte
r measuring the density.
• The system checks the RADC Patch.
6. If OK, click Clos
e to return to the “Max Setup Screen.”
NOTE: It is not necessary to run this routine to perform Max Setup. This routine can be
used as a quic
