• Code: 13.11.00
• Display: 13.11.00 JAM INSIDE UPPER RIGHT DOOR
• Description: Paper is jammed inside the upper right door. There is a jam in the oblique roller area between sensor SR8001 (paper reversing sensor) and SR12 (top of page sensor), or in the fuser.
• Remedy: 1. Follow the onscreen help to clear the jam. 2. Check for obstructions in the fuser. 3. Check for obstructions in the duplexer. 4. Ensure that media meets specifications. 5. Ensure that the ETB rollers roll freely. 6. Ensure that there is no obstruction at the bottom of the ETB.

• Code: 13.12.07
• Display: 13.12.07 Jam In Stapler
• Description: The stapler could not finish its cycle but was able to return to the home position If the stapler drive does not return to home position (HP) during the normal cycle, the stapler/stacker driver signals M1304 (stapler motor) to rotate once in reverse. If the HP signal is now detected, the stapler/ stacker driver sends a signal to the formatter that a staple jam is present.
• Remedy: 1. Remove the staple cartridge and any loose staples or staples that might be obstructing stapler movement. 2. Remove one sheet of staples from staple cartridge and try again. 3. Inspect the staple cartridge for damage. Replace the staple cartridge if it is damaged. 4. Verify that genuine HP staples are being used. NOTE: Staples come preloaded in the staple cartridge and cannot be ordered separately as a refill from HP. 5. If none of the above corrects problem, replace the stapler/stacker unit.

• Code: 13.12.08
• Display: 13.12.08 Jam In Left Accessory
• Description: Stay jam in accumulator. Paper sensor PS 1302 stayed activated longer than expected. This signal is generated by sensor PS1302 (delivery sensor). PS1302 is located just before the delivery rollers. In order to reach or see the sensor arm, lift the upper delivery rollers and upper paper-path guide plate. You will now be able to see and toggle the sensor arm activating PS1302.
• Remedy: 1. Remove any jammed paper obstructing the paper path to the delivery rollers. 2. Turn the MFP off then on. 3. If the error persists, replace the stapler/ stacker unit.

• Code: 13.12.09
• Display: 13.12.09 Jam In Left Accessory
• Description: Stay jam. Inlet-paper sensor PS1501 remained activated longer than expected. This signal is generated by sensor PS1501 (paper-inlet sensor). PS1501 is located under the lower entrance guide plate with the sensor arm extending up through the guide plate and into the paper path.
• Remedy: 1. Slide the mailbox device away from the MFP and remove any paper found entering the mailbox device or exiting the MFP. 2. Slide the mailbox back into the MFP and check for an error. 3. If the error persists, turn the MFP off then on. 4. If none of the above corrects the problem, replace the MBM unit.

• Code: 13.12.09
• Display: 13.12.09 Jam In Left Accessory
• Description: Stay jam at the entrance to the stapler/ stacker. Sensor PS1301 stayed activated longer than expected. This signal is generated by sensor PS1301 (paper-inlet sensor). PS1301 is located under the lower-entrance guide plate with the sensor arm extending up through the guide plate and into the paper path.
• Remedy: 1. Slide the stapler/stacker away from the MFP and remove any paper found entering the stapler/stacker or exiting the MFP. 2. Slide the stapler/stacker back into the unit and check for an error. 3. If the error persists, turn the MFP off then on. 4. If none of the above corrects the problem, replace the stapler/stacker unit.

• Code: 13.12.10
• Display: 13.12.10 Jam In Left Accessory
• Description: Delay jam. Paper did not arrive at the paperinlet sensor PS1501 within the expected time. This signal is generated from sensor PS1501 (paper-inlet sensor). PS1501 is located under the lower entrance guide plate with the sensor arm extending up through the guide plate and into the paper path.
• Remedy: 1. Remove the paper jam. 2. Open a new ream of paper and replace the paper in the paper tray. Try running the job again. If jamming stops, the problem is most likely excessive paper curl leaving the fuser. This is caused by damp paper from high humidity or poor-quality paper. 3. If the error persists with the new ream of paper, replace the MBM unit.

• Code: 13.12.10
• Display: 13.12.10 Jam In Left Accessory
• Description: Delay jam in entry. Paper did not arrive at the paper-inlet sensor PS1301 within the expected time. This signal is generated from sensor PS1301 (paper-inlet sensor). PS1301 is located under the lower entrance guide plate with the sensor arm extending up through the guide plate and into the paper path.

• Code: 13.12.11
• Display: 13.12.11 Jam In Left Accessory
• Description: Initial jam. At power on, paper was present at the entrance of the MBM at sensor PS1501. This signal is generated by sensor PS1501 (paper-inlet sensor). PS1501 is located under the lower entrance guide plate with the sensor arm extending up through the guide plate and into the paper path.
• Remedy: 1. Remove any paper found in the entrance guides of the MBM that might be activating PS1501. 2. Turn the MFP off then on. 3. If the error persists, replace the MBM unit.
