Kyocera ECOSYS M6235cidn
Troubleshooting. Jam Code: J0501 - J0504
J0501/J0502/J0503/J0504: No paper feed from cassette 1 - 4
Remark: prior check point when no cassette feed occurs
The next sensor does not turn on after the feed clutch turns on when feeding from cassette 1- 4.
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Re-loading paper | The cut-end of the paper is crushed. | Fan the paper well and load it by reversing the paper direction |
| 2 | Checking the paper | The paper leading edge is bent. | Remove the bent paper. |
| 3 | Checking the paper | The paper is curled downward or wavy. | Correct or replace paper. If you cannot get user agreement about the paper replacement, relocate the leading end of paper and the trailing end or reload paper upside down. |
| 4 | Checking the paper | Unspecified papers are used. | Explain to the user to use the paper within the specifications. |
| 5 | Checking the paper | foreign objects are on the paper. | Remove the paper with foreign objects. |
J0501: Cassette no feed
Condition: No marks of paper feed at the paper leading edge and the lift plate does not ascend
During paper feed from cassette 1, the leading edge does not come out from the cassette (no mark of paper feed at the leading edge).
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Checking the connection | The connector or FFC is not connected properly. Or, the wire or FFC is faulty. | Reconnect the following wire connectors and clean the FFC and reconnect. If there is no continuity, replace the wire. If the FFC terminal section is deformed or FFC is broken, replace the FFC. • Lift motor - Engine relay PWB • Engine relay PWB - Main/ engine PWB |
| 2 | Checking the driving parts | The lift motor drive is not transmitted to the lift plate drive parts because of the engagement failure. | If there are any problems such as breakage or biting of foreign objects in the joints of the gears, couplings etc. of the motor, clean or replace them. |
| 3 | Checking the lift motor | The lift motor is not properly attached, or it is faulty. | Reattach the lift motor. If it is not repaired, replace it. |
| 4 | Replacing the lift plate | The lift plate is damaged or deformed. | Replace the lift plate. |
| 5 | Replacing the engine relay PWB | The engine relay PWB is faulty. | Replace the engine relay PWB. |
| 6 | Firmware upgrade | The firmware is faulty. | Upgrade the engine firmware to the latest version |
| 7 | Replacing the main/engine PWB | The main/engine PWB is faulty. | Replace the main/engine PWB. |
J0501: Cassette no feed
Condition: No marks of paper feed at the paper leading edge and the lift plate ascends but paper feed drive does not start
During paper feed from cassette 1, the leading edge does not come out from the cassette (no mark of paper feed at the leading edge).
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Checking the connection | The connector or FFC is not connected properly. Or, the wire or FFC is faulty. | Reconnect the following wire connectors and clean the FFC and reconnect. If there is no continuity, replace the wire. If the FFC terminal section is deformed or FFC is broken, replace the FFC. • Feed clutch - Engine relay PWB • Conveying developer motor - Engine relay PWB • Engine relay PWB - Main/ engine PWB |
| 2 | Checking the paper feed shaft and the pin | Feed roller does not rotate as feed shaft and feed pin of the feed roller is not attach properly. | Reattach the feed shaft and feed pin. If there is deformation, etc., replace them. |
| 3 | Checking the paper feed clutch | The paper feed clutch is not connected, so the paper feed roller does not rotate. | Reattach the feed clutch. If it is not repaired, replace it. |
| 4 | Removing the foreign objects and checking the operation of the actuator | The lift sensor is on but the lift plate does not go up to the upper limit position. | Remove the piece of paper or the foreign objects. And, check the actuator of the lift sensor turns on by rising the lift plate. Reattach the actuator if necessary. |
| 5 | Checking the drive gear | The drive from the conveying developer motor is not transmitted. | Replace the faulty drive parts in the conveying drive unit such as a gear. |
| 6 | Checking the conveying developer motor | The conveying developer motor is not driven and feed roller does not rotate | Reattach the conveying developer motor. If it is not repaired, replace it. |
| 7 | Replacing the engine relay PWB | The engine relay PWB is faulty. | Replace the engine relay PWB. |
| 8 | Firmware upgrade | The firmware is faulty. | Upgrade the engine firmware to the latest version |
| 9 | Replacing the main/engine PWB | The main/engine PWB is faulty. | Replace the main/engine PWB. |
