Black ATC Sensor Failure, Code 15
The ATC Sensor detects an insufficient amount of developer.
Note
If this failure reoccurs three times successively, an Engine NVRAM value is set
preventing further printer use until the Clear Tech Rep Fault (see pg. 6-20) is
performed.
If this error is intermittant, replace the black developer clutch.
