• Code: SC18-21
• Description: When the upper limit sensor /2 (PS12) is OFF, the PS12 does not turn ON within 20 seconds after the paper lift motor /2 (M26) turns ON for lifting operation. And at this time, an error detection signal (24V cut off) is detected.
• Causes: Printer control board (PRCB)
• Remedy: No error code is displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. Since the lifting operation of the tray is not completed, "Set paper in the tray 2" is displayed on the operation board.

• Code: SC18-22
• Description: When the upper limit sensor /2 (PS12) is OFF, the PS12 does not turn ON within 20 seconds after the paper lift motor /2 (M26) turns ON for lifting operation. And at this time, an The locking of the paper lift motor /1 (M42) is detected. When the M42 is ON, an error detection signal of the M42 is detected.error detection signal (blowout of a fuse) is detected.
• Causes: Printer control board (PRCB)
• Remedy: No error code is displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. Since the lifting operation of the tray is not completed, "Set paper in the tray 2" is displayed on the operation board.

• Code: SC18-23
• Description: When the upper limit sensor /2 (PS12) is OFF, the PS12 does not turn ON within 20 seconds after the paper lift motor /2 (M26) turns ON for lifting operation. And at this time, an error detection signal is not detected.
• Causes: Paper lift motor /2 (M26)
• Remedy: No error code is displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. Since the lifting operation of the tray is not completed, "Set paper in the tray 2" is displayed on the operation board.

• Code: SC18-30
• Description: The locking of the paper lift motor /1 (M42) is detected. When the M42 is ON, an error detection signal of the M42 is detected.
• Causes: Paper lift motor /1 (M42) Upper limit sensor /1 (PS71)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC18-31
• Description: When the upper limit sensor /1 (PS71) is OFF, the PS71 does not turn ON within 20 seconds after the paper lift motor /1 (M42) turns ON for lifting operation. And at this time, an error detection signal (24V cut off) is detected.
• Causes: DC power supply /2 (DCPS/ 2)
• Remedy: No error code is displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. Since the lifting operation of the tray is not completed, "Set paper in the tray 3" is displayed on the operation board.

• Code: SC18-32
• Description: When the upper limit sensor /1 (PS71) is OFF, the PS71 does not turn ON within 20 seconds after the paper lift motor /1 (M42) turns ON for lifting operation. And at this time, an error detection signal (blowout of a fuse) is detected.
• Causes: PF drive board (PFUDB)
• Remedy: No error code is displayed on the operation board, but displayed only on the data collection, the list output and the CSRC. Since the lifting operation of the tray is not completed, "Set paper in the tray 3" is displayed on the operation board.
