009-038 (ATC_LED): actuates the LED ON/OFF.
009-039 (Opening/closing of the shutter and TC measurement):
Measurement of the TC: NVM 775-982 (This function requires that the desired developer
housing is facing the ATC Sensor. Perform the following steps:
a.
Enter sub-system check on the UI and sub-system test on the PWS for machine
diagnostics. Select developer unit check.
b. For best observation, remove machine Right Upper Cover PL 11.2.
c. Press Start (if using the UI) or move desired developer into position. Please note the
ATC Sensor is opposite the development position. (UI diagnostics) Select Black,
results in Yellow at ATC Sensor position. Select Magenta, results in Cyan at ATC
Sensor position. Select Cyan results in Black at ATC Sensor position. Select Yellow,
results in Home position. Select Home, results in Magenta at ATC Sensor position.
d. Close “developer unit check” screen. The desired developer housing remains in
position.
e. Enter dC330 Component control. Enter 009-039 and press Start. (Shutter activa-
tion). Close dC330.
f. Enter NVM read \ write. NVM 775-982 = TC reading for desired color. (Black is not
detectable with ATC Sensors) Value range 140 ~ 200 for selected color.
g. If 775-982 is out of given range, perform steps b) through h) of Appendix 1. If prob-
lem continues refer to “Hardware Repairs”.
9. Check the following NVM and ensure the values are set to given value. Correct values if
needed and repeat steps b) through g) of Appendix 1
10. dC131 (NVM) after the ATC Sensor is implemented.
11.Check that the following dC131 values have been added according to the ATC Sensor
implementation. NVM are noted if values are judgements or result readings to clarify
some NVM are readings and may vary.
