• Code: SC559
• Description: Three Successive Paper Jams in Fusing Unit
  This SC only occurs if SP1159 is on, and a jam occurred in the fusing unit for three consecutive sheets of paper. With SP1159 set to "1" the machine operation can be restored only by the service technician. The paper cooling job time sensor detected paper late for 3 counts.
• Causes: • Remove the paper that is jammed in the fusing unit. • Make sure that the fusing unit is clean and has no obstacles in the paper feed path.

• Code: SC561
• Description: Heating roller non-contact thermistor error 1
  The temperature measured by the heating roller thermistor (non-contact) on the end of the heating roller did not reach the prescribed warm-up temperature within 1 sec.
• Causes: • Loose, broken, damaged connector • Defective thermistor

• Code: SC562
• Description: Heating roller non-contact thermistor error 2
  After the main switch is turned on or the cover is closed, the heating roller temperature does not reach the ready temperature within 100 sec. after the heater switches on. -or- The heating roller did not reach the ready temperature within 150 sec.
• Causes: • Do SP5810 to cancel the SC fusing code • Defective hot roller thermistor • Heating roller disconnected, defective

• Code: SC563
• Description: Heating roller non-contact thermistor error 3
  The thermistor 2 (of the heating roller) detected a temperature over 250°C 10 times within 1 sec.
• Causes: • Do SP5810 to cancel the SC fusing code. • TRIAC short, AC drive board defective • VBCU defective

• Code: SC564
• Description: Heating roller non-contact thermistor error 3
  The thermistor detected a temperature over 260°C.
• Causes: • Do SP5810 to cancel the SC fusing code. • TRIAC short, AC drive board defective • VBCU defective

• Code: SC565
• Description: Heating roller fusing lamp on error
  After fusing belt reached warm-up temperature, the heating roller fusing lamp remained on for 20 sec. while the hot roller was not rotating.
• Causes: • Do SP5810 to cancel the SC fusing code. • Thermistor damaged, or out of position • Fusing lamp disconnected, broken

• Code: SC568
• Description: Pressure roller lift error 1
  Even after the leading edge of the paper reached the fusing exit sensor, the pressure roller lift motor did not raise the pressure roller.
• Causes: • Pressure roller lift sensor connection loose, broken, damaged • Clean the pressure roller lift sensor • Pressure roller lift harness loose, broken, damage • Pressure roller lift motor blocked by an obstruction • Pressure roller lift motor defective

• Code: SC569
• Description: Pressure roller lift error 2
  Pressure roller lift motor not operating correctly. (No signal to indicate completion of operation.)
• Causes: • Pressure roller lift sensor connection loose, broken, damaged • Clean the pressure roller lift sensor • Pressure roller lift harness loose, broken, damage • Pressure roller lift motor blocked by an obstruction • Pressure roller lift motor defective
