• Code: SC18-22#
• Description: When the upper limit sensor /2 (PS21) is OFF, PS21 does not turn ON within a specified period of time after the paper lift motor / 2 (M20) turns ON for lifting operation. And at this time, an error detection signal (blowout of ICP) is detected.
• Causes: Paper lift motor /2 (M20) Printer control board (PRCB) Upper limit sensor /2 (PS21) DC power supply /2 (DCPS2) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 2

• Code: SC18-23#
• Description: When the upper limit sensor /2 (PS21) is OFF, PS21 does not turn ON within a specified period of time after the paper lift motor / 2 (M20) turns ON for lifting operation. And at this time, an error detection signal is not detected.
• Causes: Paper lift motor /2 (M20) Printer control board (PRCB) Upper limit sensor /2 (PS21) DC power supply /2 (DCPS2) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 2

• Code: SC18-30
• Description: The locking of the paper lift motor /3 (M21) is detected. When M21 is ON, an error detection signal of the M21 is detected.
• Causes: Paper lift motor /3 (M21) Printer control board (PRCB) Upper limit sensor /3 (PS22) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 3

• Code: SC18-31#
• Description: When the upper limit sensor /3 (PS22) is OFF, PS22 does not turn ON within a specified period of time after the paper lift motor / 3 (M21) turns ON for lifting operation. And at this time, an error detection signal (24V cut off) is detected.
• Causes: Paper lift motor /3 (M21) Printer control board (PRCB) Upper limit sensor /3 (PS22) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 3

• Code: SC18-32#
• Description: When the upper limit sensor /3 (PS22) is OFF, PS22 does not turn ON within a specified period of time after the paper lift motor / 3 (M21) turns ON for lifting operation. And at this time, an error detection signal (blowout of ICP) is detected.
• Causes: Paper lift motor /3 (M21) Printer control board (PRCB) Upper limit sensor /3 (PS22) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 3

• Code: SC18-33#
• Description: When the upper limit sensor /3 (PS22) is OFF, PS22 does not turn ON within a specified period of time after the paper lift motor / 3 (M21) turns ON for lifting operation. And at this time, an error detection signal is not detected.
• Causes: Paper lift motor /3 (M21) Printer control board (PRCB) Upper limit sensor /3 (PS22) Loose connection Tray rear end restriction plate misaligned Paper improperly loaded Tray 3

• Code: SC18-40
• Description: The locking of the paper lift motor (M100) is detected. When the paper lift motor (M100) is ON, an error detection signal of M100 is detected in succession for 1 second.
• Causes: Paper lift motor (M100) DC power supply /2 (DCPS2) LU drive board (LUDB) Lower limit sensor (PS101) Upper limit sensor (PS109) Loose connection

• Code: SC18-41#
• Description: When the upper limit sensor (PS109) or the lower limit sensor (PS101) is OFF, PS109 or PS101 does not turn ON within a specified period of time after the paper lift motor (M100) turns ON for its lifting or lowering operation. And at this time, an error detection signal (24V cut off) is detected.
• Causes: Paper lift motor (M100) DC power supply /2 (DCPS2) LU drive board (LUDB) Lower limit sensor (PS101) Upper limit sensor (PS109) Loose connection
