• Code: E719
• Description: The communication between the card reader and the image processor PCB is disrupted.
  Note: If E719 is indicated, the fault in communication is retained by the RAM on the image processor even when the power switch has been turned off and then on; be sure to execute #12 CLEAR - CARD in service mode before making corrections.
• Causes: The wiring is faulty (short circuit, open circuit). The card reader is faulty. The image processor PCB is faulty.
• Remedy: 1) Connector Is the connection and the wiring for the connector (J1131) of the card reader and the connector (J210) on the image processor PCB normal? NO : Correct the connection. 2) Image processor PCB Try replacing the card reader. Is the fault corrected? YES : End. NO : Replace the image processor PCB.

• Code: E805
• Description: After the heat discharge fan drive signal is generated, the fan lock detection signal does not arrive for a specific period of time.
• Causes: The fan wiring is faulty (short circuit, open circuit). The heat discharge fan (FM101) is fautly. The DC controller PCB is faulty.
• Remedy: 1) Foreign matter Is there foreign matter that prevents the rotation of the fan? YES : Remove the foreign matter. 2) Wiring, Connector Is the connection and wiring of the connector (J951) of the heat discharge fan (FM101) and the connector (J106) on the DC controller PCB normal? NO : Correct the wiring. 3) Heat discharge fan (FM101), DC controller PCB Try replacing the heat discharge fan (FM101). Is the fault corrected? YES : End. NO : Replace the DC controller PCB.
