• Code: E061-0007
• Description: At time of potential control, a specific level of potential is absent. Or, the limiter goes on.
  During adjustment of EPC offset, the potential that is read is outside the +/-30 V range.
• Remedy: Turn off and then on the main power.

• Code: E061-0008
• Description: At time of potential control, a specific level of potential is absent. Or, the limiter goes on.
  During dark area potential adjustment, the sampling value is too low.
• Remedy: Turn off and then on the main power.

• Code: E061-0010
• Description: At time of potential control, a specific level of potential is absent. Or, the limiter goes on.
  The sampling of the light area potential is faulty.
• Remedy: Turn off and then on the main power.

• Code: E070-00xx
• Description: There is an error in the detection of the ITB home position. xx=01: ITB home position sensor B, xx=02: ITB home position sensor A; only at ITB 1/1 speed; XX=00: no distinction
  The home position of the intermediate transfer belt is not detected within a specific period of time . The ITB HP sensor is faulty.
• Remedy: Turn off the main power, and check the DC controller PCB and the ITB HP sensor; then, turn on the main power.

• Code: E070-01xx
• Description: There is an error in the detection of the ITB home position. xx=01: ITB home position sensor B, xx=02: ITB home position sensor A; only at ITB 1/1 speed; XX=00: no distinction
  The period of time between when the home position of the intermediate transfer belt is detected and the next home position is detected is longer than specified . The presence of a tear may have caused the sensor to wrongly identify it as indicating the home position.
• Remedy: Turn off the main power, and check the drive of the intermediate transfer belt; then, turn on the main power.

• Code: E070-02xx
• Description: There is an error in the detection of the ITB home position. xx=01: ITB home position sensor B, xx=02: ITB home position sensor A; only at ITB 1/1 speed; XX=00: no distinction
  The period of time between when the home position of the intermediate transfer belt is detected and when the next home position is detected is shorter than specified . The intermediate transfer belt slips on the drive roller, causing a delay in the timing at which the home position is detected.
• Remedy: Turn off the main power, and check the surface of the intermediate transfer belt for a tear; then, turn on the main power.

• Code: E070-03xx
• Description: There is an error in the detection of the ITB home position. xx=01: ITB home position sensor B, xx=02: ITB home position sensor A; only at ITB 1/1 speed; XX=00: no distinction
  The detection of the home position of the intermediate transfer belt has failed once. ITB home position sensor B and ITB home position sensor A must occur alternately; however, the same state has been detected continuously.
• Remedy: Turn off the main power, and check the DC controller PCB and the ITB HP sensor; then turn on the main power.

• Code: E073-0001
• Description: With the front door closed, the transfer drawer connector or the transfer frame drawer connector is not connected.
  The result of detecting the feed unit indicates the absence of the unit.
• Remedy: Turn off and then on the main power.
