Procedure (Sub-code: 200.01)

Step	Action	Yes	No
1	Check the Input sensor area for jammed media fragments. Is the paper path free of partially fed or jammed media?	Go to step 2.	Clear the paper path of any media fragments.
2	Check the jam access cover if it is blocking the Input sensor. Is it blocking the Input sensor?	Replace the jam access cover.	Go to step 3.
3	Check the Input sensor cable for proper connection. Is it properly connected?	Go to step 4.	Reseat the cable.
4	Enter the Service Mode and perform a sensor check: Select [Service Mode] -> [State Confirmation] -> [Sensor Check] -> [Base Sensor]. Does the sensor state on the operation panel display change when it is toggled?	Go to step 5.	Replace the input sensor.
5	Does the error remain?	Contact the next level of support.	The problem is solved.

Step	Action	Yes	No
1	Check the paper source. Is the paper from the MPF?	Go to step 2.	Go to step 5.
2	Check the MPF pick roller and separator pad for damage and contamination. Are they free of damage and contamination?	Go to step 3.	Replace the MPF pick roller and separator pad.
3	Check the MPF solenoid for proper operation: • Remove the left cover. • Enter the Service Mode and perform a paper passage test: Select [Service Mode] -> [State Confirmation] -> [Paper Passage Test] -> [Manual Feed], and touch Start key. • Check if the MPF solenoid moves when doing the feed test. Does it move when doing the feed test?	Go to step 4.	Replace the MPF solenoid.
4	Make sure the MPF gearbox spring is properly installed and free of damage. Check the MPF gearbox for wear or damage. Are they free of wear or damage?	Go to step 5.	Replace the MPF gearbox.
5	Check the Input sensor area for jammed media fragments Is the paper path free of partially fed or jammed media?	Go to step 6.	Clear the paper path of any media fragments.
6	Check the media present sensor and media present sensor flag for: • Proper operation • Wear or damage Do they properly operate, and are they free of wear or damage?	Go to step 7.	Replace either the media present sensor or media present sensor flag, or both.
7	Check the jam access cover if it is blocking the Input sensor. Is it blocking the Input sensor?	Replace the jam access cover.	Go to step 8.
8	Check the Input sensor cable for proper connection. Is it properly connected?	Go to step 9.	Reseat the cable.
9	Enter the Service Mode and perform a sensor check: Select [Service Mode] -> [State Confirmation] -> [Sensor Check] -> [Base Sensor]. Does the sensor state on the operation panel display change when it is toggled?	Go to step 10.	Replace the Input sensor.
10	Does the error remain?	Contact the next level of support.	The problem is solved.

Procedure (Sub-code: 200.09, 200.10, 200.11, 200.12, 200.13, 200.14, 200.15, 200.23, 200.24, 200.29, 200.30)

Step	Action	Yes	No
1	Check the LSU cables for proper connection. Are they properly connected?	Go to step 2.	Reseat the cables.
2	Inspect the LSU cables and connectors. Are they free of damage?	Go to step 3.	Replace the LSU.
3	Check the Input sensor cable for proper connection. Is it properly connected?	Go to step 4.	Reseat the cable.
4	Enter the Service Mode and perform a paper passage test: Select [Service Mode] -> [State Confirmation] -> [Paper Passage Test] -> [Tray 1], and touch Start key. Does it pass the test?	Go to step 5.	Replace the LSU.
5	Enter the Service Mode and perform a sensor check: Select [Service Mode] -> [State Confirmation] -> [Sensor Check] -> [Base Sensor]. Does the sensor state on the operation panel display change when it is toggled?	Go to step 6.	Replace the Input sensor.
6	Check the controller board for any damage. Is it free of damage?	Go to step 7.	Replace the controller board.
7	Does the error remain?	Contact the next level of support.	The problem is solved.

Procedure(Sub-code: 200.16)

Step	Action	Yes	No
1	• Remove the main drive gearbox. • Check the main drive gearbox cable for proper connection. Is it properly connected?	Go to step 2.	Reseat the cable.
2	• Remove the main drive gearbox. • Check the gears of main drive gearbox for wear or damage. Are they free of wear or damage?	Go to step 3.	Replace the main drive gearbox.
3	Check the main drive motor for proper operation: • Remove the main drive gearbox. Note: Do not disconnect the main drive gearbox cable. • Enter the Service Mode and perform a paper passage test: Select [Service Mode] -> [State Confirmation] -> [Paper Passage Test] -> any input source, and touch Start key. • Check if the main drive motor rotates when doing the feed test. Does it rotate when doing the feed test?	Go to step 4.	Replace the main drive gearbox.
4	Check the fuser gear for damage or toner contamination. Is it free of damage and contamination?	Replace the controller board.	Replace the fuser.
