• Code: 797-18
• Description: Book Door Lock Solenoid (SOL5) Error PB (D391) The book stack door is locked but the book door sensor (S98) did not go OFF.
• Causes: • Book door sensor (S98) defective • Book door lock solenoid (SOL5) defective • Solenoid or sensor harness loose, broken, defective
• Remedy:

• Code: 797-19
• Description: Glue Heater (HTR1) Error PB (D391) The heater failed to start because: 600 sec. after the bookbinder left the energy save mode, the glue thermistor did not detect the target temperature (153°C±5). -or- After the glue thermistor detected a glue temperature of 50°C, it did not detect a temperature above 140°C within 200 sec.
• Causes: • Heater (HTR1) defective • Glue thermistor (S56) defective
• Remedy:

• Code: 797-2
• Description: Grip End Sensor (S94) Error PB (D391)
• Causes: The grip end sensor (S94) did not go OFF after the grip unit released the signature and moved the prescribed distance. • Book grip motor (M43) defective • Grip end sensor (S94) defective • Sensor or motor harness loose, broken, defective The grip end sensor (S94) did not go ON because the grip unit did arrive at the sensor position. • Book grip motor (M43) defective • Grip end sensor (S94) defective • Sensor or motor harness loose, broken, defective • Data received for signature data was incorrect.
• Remedy:

• Code: 797-20
• Description: Electrical Short in the Gluing Unit PB (D391) A short circuit or wire breakage occurred in the gluing unit. The glue thermistor (S56) detected: • A temperature over 200°C more than 1 sec. (short circuit) • A temperature of less than 5°C for more than 1 sec. or more than 10 sec. after power on (wire breakage) • The AD value of the glue level thermistor (S58) remained at 1023 for 10 sec (wire breakage).
• Causes: • Heater (HTR1) defective • Glue thermistor (S56) defective
• Remedy:

• Code: 797-21
• Description: Temperature Detection Error PB (D391)
• Causes: After adjustment of the glue temperature, the glue temperature thermistor (S56) detected a temperature lower than 135C for more than 10 sec. • Heater (HTR1) defective • Glue thermistor (S56) defective The glue level thermistor detected a temperature higher than 170°C for longer than 10 sec. after the glue had warmed up. -or- The glue level thermistor detected a temperature higher than 100°C for longer than 10 sec. after the glue had warmed up. • Glue level thermistor (S58) defective
• Remedy:

• Code: 797-22
• Description: Protection Circuit Error PB (D391) The thermostat (THSW1) inside the gluing unit detected an abnormally high temperature.
• Causes: • Glue heater (HTR1)defective • Thermostat (THSW1) defective
• Remedy:

• Code: 797-23
• Description: Glue Surface Error 1 PB (D391)
• Causes: The surface of the glue in the vat did not reach the lower limit position. This error occurred when the glue surface was detected below the lower limit position 4 times in succession during the glue replenishment cycle. • Glue has clogged in the vat • Glue supply defective • Glue level thermistor (S58) defective The glue level thermistor could not detect the glue surface at the upper limit position: 1) After glue was detected above the low limit mark, and 2) After 12 glue packets were supplied, and 3) No glue had been recently applied. • Glue has clogged in the vat • Glue level thermistor (S58) defective
• Remedy:

• Code: 797-24
• Description: Glue Surface Error 2 PB (D391) Without a glue vat refill, the glue level thermistor could not detect the level of the glue below the upper limit (full) level, even after the application of 25.42 g of glue.
• Causes: • Glue application abnormal (not applying correctly) • Glue level thermistor (S58) defective
• Remedy:
