• Code: SC42-02
• Description: The blowout of a fuse for the scanner cooling fan (FM19) in the scanner drive board (SDB) is checked. An abnormal condition occurs with the FM19 EM signal a specified period of time after the FM19 turns ON. This abnormal condition recurs even a specified period of time after the FM19 is turned OFF and then turned ON, and an error detection signal (blowout of a fuse) is detected. At this time, an error detection signal (24V cut off) is not detected.
• Causes: Scanner drive board (SDB) Scanner cooling fan (FM19)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-03
• Description: The rotation of the scanner cooling fan (FM19) is checked. An abnormal condition occurs with the FM19 EM signal a specified period of time after the FM19 turns ON. This abnormal condition recurs even a specified period of time after the FM19 is turned OFF and then turned ON, and an error detection signal (24V cut off/blowout of a fuse) is not detected.
• Causes: Scanner cooling fan (FM19)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-04
• Description: The rotation of the suction fan /1 (FM6) is checked, and 24V power source is also checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after the FM6 turns ON. This abnormal condition recurs even a specified period of time after the FM6 is turned OFF and then turned ON, and an error detection signal (24V cut off) is detected.
• Causes: DC power supply /2 (DCPS/ 2)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-05
• Description: The blowout of a fuse for the suction fan /1 (FM6) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after the FM6 turns ON. This abnormal condition recurs even a specified period of time after the FM6 is turned OFF and then turned ON, and an error detection signal (blowout of a fuse) is detected. At this time, an error detection signal (24V cut off) is not detected.
• Causes: AC drive board (ACDB) Suction fan /1 (FM6)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-06
• Description: The rotation of the suction fan /1 (FM6) is checked. An abnormal condition occurs with the FM6 EM signal a specified period of time after the FM6 turns ON. This abnormal condition recurs even a specified period of time after the FM6 is turned OFF and then turned ON, and an error detection signal (24V cut off/blowout of a fuse) is not detected.
• Causes: AC drive board (ACDB) Suction fan /1 (FM6)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-07
• Description: The EM signal of the suction fan /1 (FM6) is ON when the printing is started.
• Causes: Suction fan /1 (FM6)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-08
• Description: The rotation of the suction fans /2 (FM7) and /3 (FM8) is checked, and the 24V power source is also checked. An abnormal condition occurs with the FM7/FM8 EM signal a specified period of time after the FM7/FM8 turns ON. This abnormal condition recurs even a specified period of time after the FM7/FM8 is turned OFF and then turned ON, and an error detection signal (24V cut off) is detected.
• Causes: DC power supply /2 (DCPS/ 2)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-09
• Description: The blowout of a fuse for the suction fans /2 (FM7) and /3 (FM8) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM7/FM8 EM signal a specified period of time after the FM7/FM8 turns ON. This abnormal condition recurs even a specified period of time after the FM7/FM8 is turned OFF and then turned ON, and an error detection signal (blowout of a fuse) is detected. At this time an error detection signal (24V cut off) is not detected.
• Causes: AC drive board (ACDB) Suction fan /2 (FM7) Suction fan /3 (FM8)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).
