How to Fix Epson L1800 0x09 Load Position Control Over Speed Error

If you're using the Epson L1800 and run into the 0x09 Load Position Control Over Speed error, you're not alone. This issue can be frustrating, especially after you've already tackled a clogging problem like a jammed capping station. Fortunately, understanding what this error means and identifying possible causes can guide you toward the right solution.

What is the 0x09 Load Position Control Over Speed Error?

The 0x09 error, also referred to as CR LOAD POSITION excess speed error, occurs when the Carriage Return (CR) motor spins faster than the printer's firmware expects during printing. Essentially, the printer detects that the carriage—which holds the printhead—is not behaving in a stable, controlled manner as it moves left to right across the paper. This lack of control could stem from mechanical faults or electronic miscommunications within the printer.

Common Causes and Fixes

Let’s break down the possible causes and what you can do about them:

1. CR Encoder Strip Failure

The encoder strip is a transparent plastic strip with fine lines that the printer uses to determine the position of the carriage. If this strip is dirty, scratched, or misaligned, the printer may misread the carriage position, leading to over-speeding errors.

Fix:

• Open your printer and locate the encoder strip (it runs horizontally behind the carriage).

• Use a lint-free cloth dampened with isopropyl alcohol to gently wipe it clean.

• Inspect for any visible damage or misalignment and reposition it if necessary.

2. Timing Belt Issues

The timing belt controls the movement of the printhead carriage. If the belt has skipped a tooth, is loose, or has become worn, the carriage may not move as expected—resulting in this error.

Fix:

• Check the belt for signs of slack, wear, or damage.

• Ensure it has proper tension (neither too loose nor too tight).

• If teeth are worn or the belt has stretched, replacement is recommended.

3. CR Motor or Motor Driver Failure

The CR motor is responsible for moving the printhead. If the motor is faulty or the motor driver on the mainboard isn't regulating speed properly, it may spin too fast or behave unpredictably.

Fix:

• Motor driver issues typically involve checking the mainboard for overheating, component failure, or power surges.

• The CR motor itself can be bench-tested using a multimeter or replaced if confirmed defective.

4. Main Board Malfunction

If the mainboard is damaged or processing incorrect signals, it could mismanage the motor’s behavior, triggering the 0x09 error.

Fix:

• Visually inspect the board for burnt components or broken traces.

• If all other parts check out and the error persists, replacing the mainboard may be necessary.

Final Thoughts and Additional Help

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We offer an in-person evaluation and repair service via our local diagnostic facility [https://bchtechnologies.com/printer-repair-service]. Given the high demand, we operate on a first-come, first-served basis. So, it might take a few weeks before we can get your printer to drop it off. Our services are structured to repair either a whole printer or specific parts, with clear instructions on how to proceed. However, we acknowledge that our rates aren't the most economical. Thus, we highly recommend that you resort to self-help via online research. You can start by checking out YouTube or visiting our YouTube channel's homepage [https://youtube.com/@bchtechnologies]. Look for specific videos using the search icon next to "About" on the right-hand side of the menu bar. I receive dozens of queries every day asking about videos for specific topics. Having created videos over the past nine years, it's challenging to remember every single one. Therefore, using YouTube's search function would be most efficient. Plus, YouTube might suggest relevant videos from other channels that could assist you.

Thanks again for reaching out, and we truly appreciate your support for our channel. Best of luck with your Epson L1800 repairs!
