The Yellow ATC Sensor detects a low TC (toner concentration).


Initial Action

• Check that Toner/Developer is present.
• Check the Yellow ATC Sensor for contamination. Ensure that the sensor is seated correctly.

NOTE:
To clear this fault, enter Component Control and set the value of NVM location 752-109 to 0.

This can be caused by many things. I've seen broken Drum contacts from improper drum installation causing Developer bead carryover. Toner dispense motor assy's failing. Developer Housing failure. DVHVPS failure.

Machine needs something, press machine status button, the one with a question marks. Check "Consumables" for low toner, drum end of life or fuser end of life. Or cleaner or waste bottle.

That error indicates low toner concentration in magenta. Enter diagnostics, select max setup, select toneup/tone down button, select trc control, select the start button. See if you get a result or a failure. If it fails replace the ATC sensor.

941 CM Toner Supply Failure. Toner Sensor Failure with Cyan or Magenta Toner

You need to remove developer assy and check the gears and sensor from dispenser assembly
