J0501/J0502: No paper feed from cassette
Condition: The paper arrives at the registration section

After the paper feed clutch turns on during paper feed from cassette 1-2, the paper leading edge comes out from the cassette but the next sensor does not turn on.

Step	Check description	Assumed cause	Measures
1	(When the paper skew occurs) Relocating the paper width guides	The locations of the paper width guides do not fit with the paper size.	Relocate the paper width guides to fit them with the paper size.
2	(When the paper skew occurs) Checking the actuator and the spring	The actuator does not operate normally.	The actuator or the spring is deformed. If the actuator does not normally operate, replace it.
3	(When the paper skew occurs) Checking the conveying guide	The paper is caught with the conveying guide.	Reattach the conveying guide. Remove the burrs on the conveying guide surface or replace the conveying guide if there are burrs on it.
4	(When the paper skew occurs) Checking the paper path	The paper is caught with a piece of paper, etc.	Remove any paper or foreign objects on the paper path and remove the burrs on the parts such as the guide or the actuator.
5	(When there is a paper loop mark) Checking the registration sensor	The registration sensor does not operate normally	Reattach the registration sensor and reconnect the wire. If not repaired, replace it.
6	Checking the main/engine PWB	The wires on the main/ engine PWB are not correctly connected, or the main/engine PWB is faulty.	Reconnect the wires on the engine PWB. Then, repair or replace them if pinched by the wire or if they have any damage. When not repaired, replace the main/engine PWB.

Step	Check description	Assumed cause	Measures
1	Checking the paper feed roller	The conveying function of the paper feed roller is not enough.	Clean the surface of paper feed roller. Replace if worn out.
2	Checking the pressure release lever and the retard holder	The press-release lever and the retard holder are attached oppositely.	Reattach the pressure release lever and the retard holder.
