Appendix 1. ATC set-up procedure
1. Install at least one new developer. The ATC Sensor must be calibrated from new devel-
oper.
2. Set 775-731 to 1 turns ATC Sensor on. (0 = off).
3. Confirm NVM 773-266 through 269 are set to 230, 230, 250, 160. (ADC Targets nominal
values).
4. Set 775-736 to 1. (Value will return to 0 after executing dC922).
5. Set 775-737 to appropriate value depending on developer material replaced for set-up.
• 1 = replacement of YMC
• 2 = replacement of Y
• 3 = replacement of M
• 4 = replacement of C
• 5 = replacement of YM
• 6 = replacement of YC
• 7 = replacement of MC
