8. Paper jam due to the sensor

Step	Check description	Assumed cause	Measures
1	Checking the sensor	The sensor is faulty.	The actuator for the PF paper feed sensor is caught. Also, if it comes off, reattach the actuator and its release spring.
2	Checking the sensor	The sensor is dirty.	When the sensor surface or photoreceptor black felt is dirty by paper dust, etc., clean them.
3	Checking the sensor	The sensor is faulty.	Check the sensor operation by executing U031 and U241, and clean or replace the sensor if it does not operate properly.

9. Paper jam due to the setting / detection failure

Step	Check description	Assumed cause	Measures
1	Checking the paper leading edge margin	The leading edge margin is not enough.	When there is no margin from the paper leading edge to 4.0mm(+1.5/-0.0mm), and, when there is no check line (fuser jam) on 20mm(+/- 1mm) from the paper leading edge of the test pattern that is output in U034,adjust the leading margin at U402.
2	Relocating the paper width guides	The paper size is misdetected.	Relocate the paper width guides or the MP paper width guides along the paper size to properly detect the paper size.
3	Checking the settings	The media type is not properly set.	If the media type is not matched to the actual paper weight (the paper jam occurs due to the paper separation failure), set the media type at [System Menu/Counter] key > [Common Settings] > "Org./ Paper Set.".

10. Paper jam due to the static electricity

Step	Check description	Assumed cause	Measures
1	Checking the ground	The static electricity accumulates.	When the main unit is installed in the low humidity environment where the static electricity easily accumulates on the conveying guide during the continuous printing, check if the discharge sheet in the eject section and the metal guide in the transfer section are grounded securely. If necessary, reattach the parts.

11. Paper jam caused by the installation environment (Papers inside the cassette are always damp.)

Step	Check description	Assumed cause	Measures
1	Checking the paper storage place	Papers have been stored in the improper place.	Ask users to store paper in a dry place. Put the dry paper into the plastic bag and seal the bag to prevent moisture from getting in.
2	Setting / Installing the cassette heater	The paper is damp.	[Models with the standard cassette heater]Connect the cassette heater and select the mode at U327 if necessary.[ Models with the optional cassette heater]Install the cassette heater and select the mode at U327 if necessary.
