Code: E580
Description: The stack tray upper limit sensor (S1) goes ON while the stack tray up/down motor (M5) is in operation.
The clock signal of the stack tray up/down clock sensor (S9) is not detected 15 times or more within 0.8 sec while the stack tray up/down motor (M5) is in operation.
It does not reach the stack tray paper height sensor (S10) 2 sec after the stack tray up/down motor (M5) rotates for ascent.
It does not leave the stack tray power height sensor (S10) 2 sec after the stack tray up/down motor (M5) starts to rotate for descent.
Causes: The stack tray up/down motor (M5) is faulty. The stack tray paper height sensor (S10) is faulty. The sensor connector is disconnected or has an open circuit. The stack tray up/down clock sensor (SW9) is faulty. The sensor connector is disconnected or has an open circuit. The stack tray up/down motor is subjected to an abnormal load. The finisher controller PCB is faulty.
Remedy: 1) Stack tray up/down motor (encoder) Try turning the encoder of the stack tray up/down motor by hand. Does it rotate smoothly? NO : Correct the mechanical mechanism. 2) Wiring Is the wiring between the finisher controller PCB and the stack tray up/down motor (M5) normal? NO : Correct the wiring. 3) Tray phase Is the left/right phase of the stack tray normal? NO : Correct the phase. 4) Stack tray up/down lock sensor (S9) Check the stack tray up/down clock sensor (S9). Is the sensor normal? NO : Replace the sensor. 5) Stack tray paper height sensor (S10) Check the stack tray paper height sensor (S10). Is the sensor normal? NO : Replace the sensor. 6) Stack tray paper limited sensor (S1), Stack tray lower limit sensor (S12) Check the stack tray upper limit sensor (S1) and the stack tray lower limit sensor (S12). Are the sensors normal? NO : Replace the sensors. 7) Stack tray up/down motor (M5), Finisher controller PCB Try replacing the stack tray up/down motor (M5). Is the fault corrected? YES : End. NO : Replace the finisher controller PCB.
Code: E585
Description: The stack retaining lever does not reach home position when the stack handling motor (M2) has been driven for a specific time (at the start of motor CCW rotation). (If the same condition is detected during stack delivery, a jam will be identified)
Causes: The stack handling motor (M2) is faulty. The stack delivery lever home position sensor (S8) is faulty. The sensor connector is disconnected or has an open circuit. The stack handling motor relay harness is faulty. The stack retaining lever is faulty. The finisher controller PCB is faulty.
Remedy: 1) Stack holding motor drive belt. Is the tension of the drive belt appropriate? NO : Loosen the screw, and correct the tension. 2) Stack handling motor (drive mechanism) Is the return roller rotating while the motor is rotating CCW? NO : Correct that drive mechanism. 3) Wiring Is the wiring between the finisher controller PCB and the stack handling motor (M2) normal? NO : Correct the wiring. 4) Stack retaining lever home position sensor (S4) Check the stack retaining lever home position sensor (S4). Is the sensor normal? NO : Replace the sensor. 5) Stack handling motor (M2), Finisher controller PCB Try replacing the stack handling motor (M2). Is the fault corrected? YES : End. NO : Replace the finisher controller PCB.
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?
