Step	Check description	Assumed cause	Measures
1	Checking the paper path	The paper is caught with a piece of paper, etc.	Remove paper strip or foreign objects adhering on the conveying path, or burrs on the parts such as guide, actuator, etc.
2	Checking the paper feed roller	The conveying function of the paper feed roller is not enough.	Clean the paper feed roller surface. If worn down, replace it.
3	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 • Engine relay PWB - Main/ engine PWB
4	Checking the paper feed clutch	The paper feed clutch is not connected, so the paper feed roller does not rotate.	Reattach the feed clutch and reinsert the connector. If it is not repaired, replace it.
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: The leading edge comes out from the cassette

The registration sensor does not turn on after the feed clutch turns on when feeding from cassette 1.

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 paper feed roller surface. If worn down, replace it.
2	(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.
3	(When the paper skew occurs) Checking the actuator and the spring	The actuator does not operate properly.	The actuator or the spring is deformed. If the actuator does not properly operate, replace it.
4	(In case paper skews) 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.
5	(When the paper skew occurs) Checking the paper path	The paper is caught with a piece of paper, etc.	Remove paper strip or foreign objects adhering on the conveying path, or burrs on the parts such as guide, actuator, etc.
6	(For marks of paper warpage) checking the connection	The connector is not properly connected 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. • Registration sensor - Main/ engine PWB
7	(When there is a paper loop mark) Checking the registration sensor	The registration sensor is not properly attached, or it is faulty.	Reattach the regist sensor. If it is not repaired, replace it.
8	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. • Middle clutch - Engine relay PWB • Engine relay PWB - Main/ engine PWB
9	Checking the middle clutch	The middle roller does not rotate due to no engagement of the middle clutch.	Reattach the middle clutch. If it is not repaired, replace it.
10	Replacing the engine relay PWB	The engine relay PWB is faulty.	Replace the engine relay PWB.
11	Firmware upgrade	The firmware is faulty.	Upgrade the engine firmware to the latest version
12	Replacing the main/engine PWB	The main/engine PWB is faulty.	Replace the main/engine PWB.
