• Code: 360-01
• Description: TD sensor adjustment error: K
  During TD sensor initialization, the output value of the black, cyan, magenta, or yellow TD sensor is not within the range of the specified value with SP3-238-001 to -004 (default: 2.5V)+-0.2V
• Causes: A TD sensor-related part is faulty. A TD sensor-related part's connection is loose. The developer's toner thickness differs from that of the initial developer.
• Remedy: • Turn the main power switch off and then back on. • Replace the PCU.
