• Code: 795-38
• Description: Temperature Detection Error PB (D391)
• Causes: Low temperature detected while regulating glue temperature. After adjustment of the glue temperature, the glue temperature thermistor (S56) detected a temperature lower than 135°C for more than 10 sec. • Heater, glue temperature thermistor (S56) defective Glue level thermistor: Error 1 The glue level thermistor detected a temperature higher than 170°C for longer than 10 sec. after the glue had warmed up. • Glue level thermistor (S58) defective Glue level thermistor: Error 2 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: 795-39
• Description: Protective Circuit Error PB (D391) • The thermostat (THSW1) inside the gluing unit detected an abnormally high temperature. • Abnormal thermostat detection
• Causes: • Glue heater defective • Thermostat defective
• Remedy:

• Code: 795-4
• Description: Bookbinder EEPROM Error PB (D391) EEPROM Read Error After EEPROM write operation was completed, the data was read from the same address.
• Causes: • Master control board EEPROM not installed, not installed correctly • EEPROM defective EEPROM Write Error When data was written to the EEPROM, the EEPROM signaled that it was busy for longer than 25 ms and did not recover. The error time exceeded three times the maximum time allowed for recovery (8 ms) • Master control board EEPROM not installed, not installed correctly • EEPROM defective
• Remedy:

• Code: 795-40
• Description: Glue Surface Error 1 PB (D391) The surface of the glue in the vat did not reach the lower or upper limit position. This error is issued when the glue surface was detected below the lower limit position 4 times in succession during the glue re-supply cycle.
• Causes: • Glue has clogged in the vat • Glue supply defective • Glue level thermistor (S58) defective
• Remedy:

• Code: 795-41
• Description: Glue Surface Error 2 PB (D391) The glue surface has not dropped below the upper limit mark. 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:

• Code: 795-42
• Description: Glue Level Thermistor (S58) Adjustment Error PB (D391) One of the following errors occurred in the adjustment data for the glue level thermistor: • Glue level thermistor 1 value (low limit) was out of the range: 128°C±14° C) • Glue level thermistor 2 value (high limit) was out of the range: 142°C±10° C) • Glue level thermistor adjustment value 1 was larger than for adjustment 1. • The difference between the values for adjustment 1 and 2 was less than 5° C.
• Causes: • Slave control board connection loose, broken, defective • Slave control board defective
• Remedy:

• Code: 795-43
• Description: Timing Sensor (S5) Adjustment Error PB (D391) The value for the adjustment of the timing sensor exceeded the upper limit. When the A/D input for the timing sensor is lower than 3.0V to 3.5V, even if the timing sensor D/A output is as high as 3.5V, the A/D input value will not fall within the 3.0-to-3.5V range. -or- The value for the adjustment of the timing sensor was lower than the lower limit. When the A/D input for the timing sensor is higher than 3.0V to 3.5V, even if the timing sensor D/A output is as low as 0.1V, the A/D input value will not fall within the 3.0-to-3.5V range.
• Causes: • Timing sensor defective • D/A converter defective • A/D converter defective
• Remedy:

• Code: 795-44
• Description: Cover Registration Sensor (S21) Error PB (D391) The value for the adjustment of the cover registration sensor was higher than or lower than the target range: 3V to 3.5V
• Causes: • Cover registration sensor (S21) defective • D/A converter defective • A/D converter defective
• Remedy:
