Troubleshooting. JAM. Misfeed at tray 4 feed section
JAM code: 14-01
Sub-code:(244.xx)
Detection timing
244.01 | Paper over tray 4 Pass through sensor on warmup. |
244.02 | Input sensor detected late feed during a pick retry from tray 4. |
244.03 | Tray 4 Pass through sensor never became covered when feeding a sheet from an option below. |
244.06 | Failed to feed from tray. Paper present sensing supported and indicates media still in tray. |
244.07 | Option tray 4 Pass through sensor never became uncovered when feeding a sheet from an option below. |
244.09 | Tray 4 Pick/lift motor lost encoder. |
244.11 | Autocomp Pick/lift motor - Encoder Never Detected in tray 4. |
244.12 | Motor ramp up error in tray 4. |
244.13 | Page to be stapled failed to feed from tray. |
244.14 | Sheets flushed from paper path either due to feed error or cartridge error. |
244.15 | One or more trays located above the source tray 4 has been pulled. |
244.16 | The engine timed out waiting for the tray 4 to report ready before the 1st pick attempt. |
244.17 | Page was not properly picked from tray 4. Have not exhausted all pick retry attempts as there are sheets committed to the paper path from below. |
244.19 | Tray 4 fail to feed error. Detected while trying to pick a sheet, and that leading edge was not detected by Pass through sensor. |
244.20 | Took too long to ramp up dc feed motor in tray 4. |
244.21 | Pick motor stall in tray 4. |
244.22 | Tray 3 Pick/lift motor underspeed. |
244.24 | DC Feed autocompensator stalled on the last pick attempt in tray 4. |
244.32 | Tray not ready. |
244.33 | Pick received but detected a tray pulled. |
244.41 | Motor 1 (Pick/lift) Elevator motor stalled. |
244.42 | Motor 1 (Pick/lift) Elevator motor PWM overflow error (underspeed). Motor underspeed (max PWM and motor underspeed, typical accordion jam). |
244.43 | Motor 1 (Pick/lift) motor ramp (end ramp - did not reach speed, typical pack feed paper jam). |
244.44 | Motor 2 (Separator/pass through) motor stalled. |
244.45 | Motor 2 (Separator/pass through) motor PWM overflow error (underspeed). Motor underspeed (max PWM and motor underspeed, typical accordion jam). |
244.46 | Motor 2 (Separator/pass through) motor ramp (end ramp - did not reach speed, typical pack feed paper jam). |
244.47 | Motor 3 motor stalled. |
244.48 | Motor 3 motor PWM overflow error (underspeed). Motor underspeed (max PWM and motor underspeed, typical accordion jam). |
244.49 | Motor 3 motor ramp (end ramp - did not reach speed, typical pack feed paper jam). |

• Pick/lift motor
• Separator/pass through motor
Procedure
Step | Action | Yes | No |
---|---|---|---|
1 | Restart the printer. Does it fail to complete the POST sequence and display a 242.01 error? |
Replace the option tray. | Go to step 2. |
2 | • Enter the Service Mode and perform a paper passage test: Select [Service Mode] -> [State Confirmation] -> [Paper Passage Test] -> [Tray 4], and touch Start key. • Cancel the test after five pages. Does the printer successfully feed the five pages into the output bin? |
The problem is solved. | Go to step 3. |
3 | Does the printer display a 242.06 error? | Replace the ACM assembly. | Go to step 4. |
4 | Check the pick roller assembly. Is it free of wear or damage? |
Go to step 5. | Replace the pick roller assembly. |
5 | Check the separator roll assembly. Is it free of wear or damage? |
Go to step 6. | Replace the separator roll assembly. |
6 | Check the tray guides, lift plate, and lift plate gears. Are they free of wear or damage? |
Go to step 7. | Replace the tray insert. |
7 | Check the ACM assembly. Is it free of wear or damage? |
Go to step 8. | Replace the ACM assembly. |
8 | Enter the Service Mode and perform a paper passage test: Select [Service Mode] -> [State Confirmation] -> [Paper Passage Test] -> [Tray 4], and touch Start key. Does the pick/lift motor gearbox pass the test? |
Go to step 9. | Replace the option tray. |
9 | Does the error remain? | Contact the next level of support. | The problem is solved. |
