ADJ 9.1 Max Setup
Purpose
To conduct a check of the machine and set it up so that excellent copy quality can be consis-
tently obtained by stabilizing the development potential and copy density.
Adjustment
Max Setup consists of 5 separate adjustments that should be performed in the following
sequence:
1. ADJ 9.7, IIT Calibration (dC945)
NOTE: Perform ADJ 9.2 only when replacing the ATC Sensor or Developer Housing.
2. ADJ 9.2, ATC Sensor Setup (dC921)
3. ADJ 9.3, TRC Control/Toner Density Setup (dC922)
4. ADJ 9.4, ADC Output (dC934)
NOTE: Perform ADJ 9.5 only when the customer requests.
5. ADJ 9.5, Manual TRC Adjust (dC924)
ADJ 9.2 ATC Sensor Setup (dC921)
Purpose
NOTE: This procedure should only be performed when the ATC Sensor or Developer Housing
has been replaced, or when there is reason to believe that the calibration values in NVM are
incorrect.
To set the calibration values [ATC Correction Coefficient], [ATC Correction Offset] in NVM to
calibrate the new ATC Sensor.
Adjustment
1. Connect the PWS to the machine and enter Diagnostic Mode (refer to Entering Diagnostic
Mode using the PWS).
2. Under the Adjustments tab, select Max Setup.
3. Select the TC/ATC Sensor Setup tab.
