When your Konica Minolta C300i printer displays paper jam error codes such as 99-13 or 99-14, it typically indicates a paper jam in specific areas of the printer. Here’s how to troubleshoot and resolve these issues:
Understanding the Error Codes:
-
Error 99-13: This code usually points to a paper jam in the fusing unit. The fusing unit is responsible for fixing the toner onto the paper using heat and pressure. A jam here might require inspecting and possibly cleaning the fuser area.
-
Error 99-14: This code generally indicates a paper jam in the exit section of the printer. This is the area where the paper exits after printing. Clearing this jam often involves checking the exit rollers and clearing any obstructions.
Fault phenomenon:
The machine prompts paper jam 99-14, the query code is: controller paper jam (when the image is stable), the front door is opened and closed, the machine prompts that the paper jam is cleared, and starts self-checking. After a while, the same code is reported again.
| Paper jam type | Controller jam (image stabilization timeout) |
| Paper jam code | 99-13, 99-14 |
| Paper jam detection timing | 99-13：Even after a predetermined period of time has elapsed since the image stabilization start command was received, the image stabilization start report is not received (registration recalculation is completed). |
| Paper jam detection timing | 99-14：After receiving the image stabilization start command, the controller's response will be lost for more than 1 minute. |

Solution:
1. Remove the transfer belt assembly and clean the color registration sensor, as shown below:
2. If step 1 cannot solve the problem, you can enter the maintenance mode, counter, maintenance call history, and check the relevant codes. If the C-4501 code is still frequent, you should also consider the laser failure.
Note:
The 99-14 code is different from the 99-03/99-13 code. The 99-03/99-13 code usually shows color blocks generated by image stability on the transfer belt, but the 99-14 code cannot find color blocks on the transfer belt. According to the manual analysis, it may be that the laser fails to pass the self-test before the image is stable. It can be checked and confirmed according to the maintenance code history. It may usually be accompanied by the C-4501 code.
Conclusion:
If your Konica Minolta C300i printer displays paper jam error codes 99-13 or 99-14, the issue likely lies in the fusing unit or exit section. Start by cleaning the color registration sensor and checking the transfer belt assembly. If the problem persists, consult the maintenance mode to diagnose any recurring issues like the C-4501 code, which may indicate a laser malfunction. By addressing these concerns promptly, you can minimize downtime and keep your printer running smoothly.
