Verify that all paper trays are configured and loaded correctly. Also verify that the media is within specifications.
Remove the tray(s) from the printer.
Verify that the custom size switch is set correctly.
Verify that the blue media width guides are set correctly.
Verify that the blue rear media guide is set correctly.
Place a fresh ream of paper in the tray after flexing (breaking) the ream.
Isolate printing functionality from each tray by performing a PAPER PATH TEST .
Jamming from Tray 1--before the paper pickup assembly
If paper jams before the paper pickup assembly, open the access cover for the Tray 1 pickup roller assembly (located in Tray 2).
Check the area for any paper in the assembly.
Inspect the pickup roller and the separation pad.
Replace the pickup roller (RG9-1529-000CN) and separation pad (RF5-3865-020CN).
If the roller and separation pad have already been replaced, replace Tray 2 (RG5-6647-100CN).
Jamming from Tray 2, 3 or 4--before the paper pickup assembly
If media jams in the tray, but before the paper pickup assembly, replace the separation roller, the cassette feed, and the cassette pickup roller (RY7-5097-000CN).
If the roller kit has already been replaced, replace the applicable tray.
Jamming in the paper pickup assembly
Check the paper pickup assembly for jammed media.
Open the covers and the electrostatic transport belt (ETB).
Remove the cyan print cartridge.
Remove any jammed media and print again and check the paper pickup assembly for any jammed paper. (A very small piece of paper could be lodged in the paper pickup assembly. See Figure 1).
Front of printer with front cover and ETB opened and the cyan cartridge removed
If paper jams continue, replace the paper pickup assembly (RG5-6670-220CN).
If the error does not clear, and changes to a 13.02.00 or a 13.09.00 , perform the sensor test. Check the status of (A) PS801 for a 13.02.00 , and (C) PS7 for a 13.09.00. To enter the SENSOR TEST , do the following:
Press (Select) to enter the MENUS .
Press (Down Arrow) to DIAGNOSTICS , then press (Select).
Press (Down Arrow) to SENSOR TEST , then press (Select).
NOTE: The control panel will display letters A through O. Each letter corresponds with a particular sensor. See Figure 3.
Verify that the sensor test letter codes indicate the following values when Trays 2, 3 and 4 are loaded with letter-sized media:Letter Value
A (top of page sensor - PS801) 0
B (fuser inlet sensor - PS8) 1
C (fuser delivery sensor - PS7) 0
D (output bin full sensor - PS6) 0
E (MP tray paper presence sensor - PS802) 0
F (Tray 2 paper presence sensor - PS903) 1
G (Tray 2 paper width switch - SW1, SW2, SW3) 1
H (Tray 2 paper length switch - SW4, SW5, SW6) 6
I (Tray 3 paper presence sensor - PS503) 1
J (Tray 3 paper width sensor - SW1, SW2, SW3) 1
K (Tray 3 paper length sensor - SW4, SW5, SW6) 6
L (Tray 4 paper presence sensor - PS503) 1
M (Tray 4 paper width sensor - SW1, SW2, SW3) 1
N (Tray 4 paper length sensor - SW4, SW5, SW6) 6
O (door - SW1) 1
If the sensor test fails for (A) PS801, check the physical location of the sensor again for obstructions, and then replace the paper sensor PCB assembly.
If the sensor test fails for (C) PS7, check the physical location of the sensor again for obstructions,
Open the top cover.
Disable the door interlock, and wait for the printer to come back up to ready.
Remove the fuser during the sensor test.
Slide a pencil inside of the rear sensor tower, and verify that when (C) PS7 is blocked, it reports a 1.
If (C) PS7 reports a 1 in the sensor test, when manually blocked, replace the fuser.
If (C) PS7 does not report a 1 in the sensor test, when manually blocked, replace the sensor and bracket assembly (RG5-6715-000CN), and DC controller (RG5-6850-060CN).

Dicka- Thank you for taking the time to post the service bulletin. I have previously read it, and eliminated those possibilities.
