Kyocera TASKalfa 7003i

(1)The cassette paper size is misdetected

Step	Check description	Assumed cause	Measures
1	Checking the actuator	The actuator does not operate properly.	Check if the actuator for the paper length detection sensor operates when inserting the cassette. If it does not properly operate, reattach the actuator.
2	Checking the wire	The connectors are not properly connected or the wire is faulty.	Clean the terminal of the following wire connectors and reinsert the connectors. Replace the wire when it has no continuity. • Paper length detection sensor - Engine PWB
3	Checking the paper width detection sensor	The paper width detection sensor operation is faulty.	Check if the paper width detection sensor turns on when inserting the cassette. If it does not turn on, reattach the paper width detection sensor.
4	Checking the wire	The connectors are not properly connected or the wire is faulty.	Clean the terminal of the following wire connectors and reinsert the connectors. Replace the wire when it has no continuity. • Paper width detection sensor - Engine PWB
5	Replacing the paper length detection sensor	The paper length detection sensor is faulty.	Replace the paper length detection sensor.
6	Replacing the paper width detection sensor	The paper width detection sensor is faulty.	Replace the paper width detection sensor.
7	Replacing the feed PWB	The feed PWB is faulty.	Replace the feed PWB.
8	Replacing the engine PWB	The engine PWB is faulty.	Replace the engine PWB.

(2)The paper size loaded in the paper deck of the large capacity feeder is misdetected.

Step	Check description	Assumed cause	Measures
1	Checking the wire	The connectors are not properly connected or the wire is faulty.	Clean the terminal of the following wire connectors and reinsert the connectors. Replace the wire when it has no continuity. • PF size detection switches 1/2 - PF main PWB • PF main PWB - Engine PWB
2	Replacing PF size detection switches 1/2	PF size detection switch 1/2 is faulty.	Replace PF size detection switch 1/2.
3	Replacing the PF main PWB	The PF main PWB is faulty.	Replace the PF main PWB in the large capacity feeder.
4	Replacing the engine PWB	The engine PWB is faulty.	Replace the engine PWB.

(3)The MP tray paper size is misdetected.

Step	Check description	Assumed cause	Measures
1	Checking the wire	The connector is not properly connected.	Clean the terminal of the following wire connectors and reinsert the connectors. Replace the wire when it has no continuity. • MP paper length detection sensor - Relay PWB • Relay PWB - Feed PWB • Feed PWB - Engine PWB
2	Checking the wire	The connector is not properly connected.	Clean the terminal of the following wire connectors and reinsert the connectors. Replace the wire when it has no continuity. • MP paper width detection sensor - Relay PWB • Relay PWB - Feed PWB • Feed PWB - Engine PWB
3	Checking the MP paper width sensor	The MP paper width detection sensor is not properly attached, or it is faulty.	Check the home position of the MP paper width sensor, and reattach it if necessary. Then, replace the sensor if it is not fixed.
4	Replacing the MP paper length switch	The MP paper length switch is faulty.	Replace the MP paper length switch.
5	Replacing the feed PWB	The feed PWB is faulty.	Replace the feed PWB.
6	Replacing the engine PWB	The engine PWB is faulty.	Replace the engine PWB.
