Checking the actuator |
The actuator does not operate properly. |
Check if the actuator for the PF paper length switch operates when the cassette is inserted. If there is something wrong with the operation,reinstall the actuator. |
| 2 |
Check the PF paper length switch and fan - shaped arm |
The PF paper length switch or fan - shaped arm is not operating normally. |
Reinstall the PF paper length switch or 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 switch shifts,and the paper width switch 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.
- 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].
