- Code: P-37
- Description: PH optical system dirt
SOS signal is not detected even once while the PH contamination detection control is being performed. - Causes: • PH unit
• CPU board (CPUB)
• Base board (BASEB) - Remedy: 1. Check the connector between the PH unit-BASEB CN13 for proper connection and correct as necessary.
2. Check CPUB for proper installation and correct as necessary.
3. Replace the PH unit.
4. Replace the CPUB
5. Replace BASEB.
- Code: P-41
- Description: Machine inside temperature sensor failure
• After turning ON, when the detected temperature of the temperature/humidity sensor (TEM/HUMS1) is 0°C.
• Turning OFF or entry in sleep mode resets the warning. - Causes: • Temperature/humidity sensor (TEM/HUMS1)
• CPU board (CPUB)
• Base board (BASEB) - Remedy: 1. Check the connector between TEM/HUMS1-BASEB CN22EB for proper connection and correct as necessary.
2. Check CPUB for proper installation and correct as necessary.
3. Replace the temperature/humidity sensor (TEM/HUMS1).
4. Replace CPUB.
5. Replace BASEB.
- Code: P-42
- Description: PH temperature sensor failure
• After turning ON, when the detected temperature of the paper feed thermistor is 0°C.
• Turning OFF or entry in sleep mode resets the warning. - Causes: • PH unit
• CPU board (CPUB)
• Base board (BASEB) - Remedy: 1. Check the connector between the PH unit-relay CN20-BASEB CN5E for proper connection and correct as necessary.
2. Check CPUB for proper installation and correct as necessary.
3. Replace the PH unit.
4. Replace CPUB.
5. Replace BASEB.
- Code: P-5
- Description: IDC sensor failure
• During IDC sensor light intensity correction, IDC sensor output is uncompleted
• During IDC base surface detective control, sensor output voltage detected is under 0.7 V or over 3.35 V
• During image stabilization (gamma correction control), detected output value for IDC sensor did not go below threshold (half the value of what is detected by IDC sensor on the belt surface) for three consecutive times (position of the pattern end is not detected). - Causes: • Transfer belt unit
• IDC sensor (IDCS1)
• High voltage unit (HVPS)
• Base board (BASEB) - Remedy: 1. Wipe clean the surface of the transfer belt with a soft cloth, if it is dirty.
2. Replace the transfer belt unit if the transfer belt is damaged.
3. Reinstall or reconnect IDCS1, connectors connecting between IDCS1-relay CN70-BASEB CN22E, if any of the foregoing parts is installed or connected improperly.
4. Clean IDCS1, if it is dirty.
5. Check the connector between HVPS CN1-BASEB CN4E for proper connection.
6. Open/close the front door, run an image stabilization sequence, and select [Service Mode] -> [State Confirmation] -> [Level History 1] to check the IDC value. IDC1: IDCS1 If the value is 1.0 V or less, replace IDCS1.
7. Replace BASEB.
