• Code: E010-0002
• Description: Unstable rotation of the Main Motor (M1)
  During motor rotation, detection is executed every 100 msec; however, the drive signal is absent 5 times in sequence.
• Remedy: 1. Check connection of the Connector (J2002/J2255/J203). 2. Replace the Main Motor (M1). 3. Replace the DC Controller PCB (UN2).

• Code: E014-0001
• Description: Unstable rotation of the Fixing Motor (M2)
  Detection is executed every 100 msec after the start of motor rotation; however, the drive detection signal is absent for 2 sec.
• Remedy: 1. Check connection of the Connector (J2001/J203). 2. Replace the Fixing Motor (M2). 3. Replace the DC Controller PCB (UN2).

• Code: E020-0000
• Description: The path between the sub hopper and the developing assembly is clogged with toner.
  The Developing Assembly Toner Sensor (S25) detects the absence of toner, while the Sub Hopper Toner Sensor (S26) detects the presence of toner. With the Developing Cylinder Clutch (CL3) turned on, the hopper feed screw motor (M16) is rotated for 1 sec intermittently 194 times; still, the Developing Assembly Toner Sensor (S25) does not detect the presence of toner. * Error occurs after the delivery if a paper in passage exists.
• Remedy: 1. Check the rotation of hopper motor gear. (If rotating, false detection by the sensor is doubted. Feed the toner to the developing unit in service mode: COPIER > FUNCTION > INSTALL > TONER-S.) 2. Replace the Developing Assembly Toner Sensor (S25). 3. Replace the Sub Hopper Toner Sensor (S26). 4. Replace the DC Controller PCB (UN2).

• Code: E024-0000
• Description: The connector of Developing Assembly Toner Sensor (S25) is disconnected.
  The Developing Assembly Toner Sensor (S25) connection detection signal is absent for 100 msec 10 times in sequence. * Error occurs after the delivery if a paper in passage exists.
• Remedy: 1. Check connection of the Connector (J2013/J209). 2. Replace the Developing Assembly Toner Sensor (S25). 3. Replace the DC Controller PCB (UN2).

• Code: E024-0001
• Description: The Developing Assembly Toner Sensor (S25) is disconnected.
  <At LOW SPEED> The Developing Assembly Toner Sensor (S25) ON counter is checked every 2.5 seconds, and the counter increments 1 count every 25 times when the sensor goes on, and 300 counts are reached. <At HIGH SPEED> The Developing Assembly Toner Sensor (S25) ON counter is checked every 1.5 seconds, and the counter increments 1 count every 15 times when the sensor goes on, and 300 counts are reached.
• Remedy: 1. Check connection of the Connector (J2013/J209). 2. Replace the Developing Assembly Toner Sensor (S25). 3. Replace the DC Controller PCB (UN2).

• Code: E025-0000
• Description: The connector of Sub Hopper Toner Sensor (S26) is disconnected.
  The Sub Hopper Toner Sensor (S26) connection detection signal is absent for 100 msec 10 times in sequence. * Error occurs after the delivery if a paper in passage exists.
• Remedy: 1. Check connection of the Connector (J2115/J2503/J207). 2. Replace the Sub Hopper Toner Sensor (S26). 3. Replace the DC Controller PCB (UN2).

• Code: E025-0001
• Description: Failure of the Bottle Motor (M17)
  When the disconnection status of the bottle motor (M17) is detected 15 times or more continuously with the 100ms cycle during the intermittent rotation When the disconnection status of the bottle motor (M17) is detected 75 times continuously with the 100ms cycle during the continuous rotation * Error occurs after delivering the remaining paper.
• Remedy: 1. Check connection of the Connector (J2216/J2503/J207). 2. Replace the Bottle Motor (M17). 3. Replace the DC Controller PCB (UN2).
