Object: Main unit, Paper feeder
| Step | Check description | Assumed cause | Measures |
|---|---|---|---|
| 1 | Checking the actuator | The actuator does not operate properly. | Check if the actuator for the paper length sensor operates when inserting the cassette. If it does not properly operate, reattach the actuator. |
| 2 | Checking the paper length sensor and fan shaped arm | The paper length sensor or the fan shaped arm does not operate correctly. | Reattach the paper length sensor or the fan shaped arm. |
| 3 | Checking the detected paper size on the operation panel | When inserting the cassette vigorously into the main unit with a large amount of paper loaded in the cassette, the paper width guide temporarily deflects, the angle of the switching lever for the paper width sensor shifts, and the paper width sensor does not turn on correctly. | After inserting the cassette vigorously into the main unit with a large amount of paper loaded in the cassette, check the paper size of the target cassette which is detected on the operation panel. ([Status/Job Cancel] key > [Paper/Supplies]) If the paper size in the cassette is not detected, pull out the cassette and insert the cassette with the normal strength. If it does not reoccur, please explain to the user not to insert the cassette vigorously. If there is concern about reoccurrence by the same operation after that, specify the paper size of the target cassette instead of [Auto]. ([System Menu/ Counter] key > [Cassette/MP tray Settings] > [Cassette 1 (to 5)]) |
| 4 | Attaching the countermeasure part to LEVER SIDE SWITCH A | If the cassette base is bent due to the shock when inserting the cassette strongly, the amount of shifting LEVER SIDE SWITCH at the cassette base bottom is insufficient. As a result, the paper width sensor is not turned On. | Attach PARTS CASSETTE LEVER ASSY SP (302L79423_) to LEVER SIDE SWITCH A. |
| 5 | Checking the connection | The connector is not connected properly, or the wire is faulty. | Clean the terminal of the following wire connectors and reconnect the connectors. If there is no continuity, replace the wire.
|
| 6 | Replacing the paper length sensor | The paper length sensor is faulty. | Replace the paper length sensor. |
| 7 | Replacing the paper width sensor | The paper width sensor is faulty. | Replace the paper width sensor. |
| 8 | Replacing the feed drive PWB | The feed drive PWB is faulty. | Replace the feed drive PWB. |
| 9 | Replacing the engine PWB | The engine PWB is faulty. | Replace the engine PWB. |
