• Common causes are loose wire connections or incorrect voltage output
• This guide covers troubleshooting and power supply replacement
• Screwdriver
• Multimeter
• First positive terminal: 42V (41.9V is acceptable)
• Second terminal: 24V
• Third terminal: 24V
• Additional 24V and 42V terminals should match labeled values
• If all voltage readings are correct, the power supply is functioning
• If any voltage reading is incorrect, the power supply is faulty and must be replaced
• Input wires:
• Positive input wire
• Negative input wire
• Ground wire
• Output terminals:
• Two terminals labeled 42V
• Two terminals labeled 24V
• Negative outputs: 24V, 24V, 42V
• Positive outputs: 24V, 24V, 42V
• Do not mix 42V and 24V connections
• Printer should now power on normally with a functioning control panel
• If issues persist, contact a DTF Station technician
