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. • PF feed sensor - PF PWB
7	(For marks of paper warpage) checking the PF feed sensor	The PF feed sensor is not properly attached, or it is faulty.	Reattach the PF feed sensor. If it is not repaired, replace it.
8	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. • PF conveying clutch - PF PWB
