• Code: SC52-03
• Description: Rotation of the cooling fan /1 (FM1) is checked. An abnormal condition occurs with the FM1 EM signal a specified period of time after the FM1 turns ON. This abnormal condition recurs even a specified period of time after the FM1 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) Cooling fan /1 (FM1) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC52-04
• Description: The rotation of the cooling fan /2 (FM2) is checked, and +24V power source is also checked. An abnormal condition occurs with the FM2 EM signal a specified period of time after the FM2 turns ON. This abnormal condition recurs even a specified period of time after the FM2 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: SC52-05
• Description: The blowout of a fuse for the cooling fan /2 (FM2) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM2 EM signal a specified period of time after the FM2 turns ON. This abnormal condition recurs even a specified period of time after the FM2 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) Cooling fan /2 (FM2) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC52-06
• Description: Rotation of the cooling fan /2 (FM2) is checked. An abnormal condition occurs with the FM2 EM signal a specified period of time after the FM2 turns ON. This abnormal condition recurs even a specified period of time after the FM2 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) Cooling fan /2 (FM2) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC52-07
• Description: The rotation of the cooling fan /3 (FM3) is checked, and +24V power source is also checked. An abnormal condition occurs with the FM3 EM signal a specified period of time after the FM3 turns ON. This abnormal condition recurs even a specified period of time after the FM3 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: SC52-08
• Description: The blowout of a fuse for the cooling fan /3 (FM3) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM3 EM signal a specified period of time after the FM3 turns ON. This abnormal condition recurs even a specified period of time after the FM3 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) Cooling fan /3 (FM3) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC52-09
• Description: Rotation of the cooling fan /3 (FM3) is checked. An abnormal condition occurs with the FM3 EM signal a specified period of time after the FM3 turns ON. This abnormal condition recurs even a specified period of time after the FM3 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) Cooling fan /3 (FM3) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC52-10
• Description: The EM signal of the cooling fan /1 (FM1) is ON when the print is started.
• Causes: Cooling fan /1 (FM1)
• Remedy: Error codes are not displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. The control of the main body is made by using a data previously obtained.
