Solving the 033506 Error on Epson WF 7710

Question: 

I'm experiencing a 033506 error on my Epson WF 7710. After watching your YouTube video on fixing this issue, I'm considering bringing my printer to your location. Could you provide an estimate for just resolving the 033506 error? I don't require a full diagnostic, just a fix for this specific problem.

Answer:

Thank you for reaching out with your question about the 033506 error on your Epson WF 7710. We at BCH Technologies value your engagement and support, especially your interest in our YouTube channel. Your feedback helps us enhance our expertise and service quality.

Understanding the 033506 Error

The 033506 error typically indicates a "Light excessive error" on your printer. This error can arise from a couple of primary issues:

• Abnormal Sensor Output: This could be a result of a sensor failure or a malfunction on the PIS (Photo Ink Sensor) board. If the printer is exposed to excessive light, such as direct sunlight from a window, it can trigger this error.
• PIS Sensor Malfunction: If moving your printer to a darker environment doesn’t resolve the issue, it suggests that the PIS sensor may be continually activated due to a fault. Replacing the PIS sensor is often a straightforward fix for this problem. You can purchase a replacement sensor (Part No. A2140859) from our website here, and we also provide a helpful installation video here.

Additional Potential Cause: Mainboard Malfunction

Another less common but possible cause of the 033506 error is a malfunction in the printer’s mainboard:

• Mainboard Issues: The mainboard controls various functions of the printer, including the operation of sensors. If there's an issue with the mainboard, it could fail to regulate the sensor correctly, leading to persistent error messages even when there's no direct issue with the sensor itself. Resolving this typically requires professional diagnostics and potentially replacing the mainboard.

Why Full Diagnostics Are Necessary

At BCH Technologies, we emphasize the importance of a full diagnostic evaluation. While it might be tempting to request a repair for just one perceived issue, our experience shows that symptoms like the 033506 error can be indicative of more complex underlying problems. Here’s why comprehensive diagnostics are crucial:

• Accurate Problem Identification: Many printer issues, initially reported as simple, turn out to be more complicated upon thorough inspection. For instance, a request to fix a “simple sensor error” can lead to discoveries of additional issues, such as electronic failures or mechanical obstructions.
• Ensuring Comprehensive Repairs: We aim to not only fix the immediate problem but also ensure that your printer operates reliably long after you leave our service center. This requires a complete understanding of all potential issues and their interactions.

Service Approach at BCH Technologies

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems.
