DTF white-ink tray mixer: check 24 V DC at the motor Source-Date (SAST): 2024-10-23 15:10 Dest: both Review-after: 2027-08-31 Status: current 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.
