## Facts

- If the mixer motor in a DTF white-ink tray stops, first check whether **24 V DC** is reaching the motor (multimeter).
- The mixer is usually wired **straight to the printer power supply**, not a separate named PSU.
- If the rest of the printer is running, 24 V should be present — look for a damaged wire before quoting a new motor.
