Question: How can I resolve the scanner error message 100016 on my Epson WorkForce Pro WF-3820? I'm unsure of how to reset the printer or address this problem.

Answer: Thank you for reaching out to us. At BCH Technologies, we deeply appreciate your engagement and support, especially regarding our YouTube channel (https://youtube.com/@bchtechnologies). Your input is invaluable in advancing our technical expertise and helping others with similar issues.

The error message 100016 on your Epson WorkForce Pro WF-3820 indicates a "HP detection failure," which can stem from several issues within the scanner component of your printer. This error can be due to a variety of problems including:

• CIS Unit Failure: This is the compact image sensor unit responsible for scanning the document. A failure here can disrupt the scanning process.
• Scanner Housing Upper or Lower Failure: The physical case around the scanner might be misaligned or damaged, interfering with the scanner's operation.
• Scanner Motor Failure: The motor moves the scanner light and lens across the document. If it fails, the scanner cannot function.
• Foreign Object: Any object obstructing the scanner's path can trigger this error.
• Main Board Failure: Less common, but a failure in the printer's main circuit board can lead to scanner errors as well.

The underlying issue is that the scanner's light unit cannot move freely. This could be because it has come off its rail, the motor has failed, or the printer housing is obstructing its movement.

For a step-by-step guide on diagnosing and fixing this issue, we've created a video that might provide the insight needed to resolve the problem. You can find the video here: Diagnosing and Fixing Scanner Error 100016. This tutorial walks through the process of identifying the specific cause of the error and the potential fixes you can apply.

Navigating printer issues can be challenging due to their technical and hands-on nature. For example, something as straightforward as a clog might need specific unclogging procedures, whereas a printer left unused might require a thorough ink system service. And the seemingly ubiquitous "paper jam" error can have countless underlying causes, making it a notorious problem in any office setting. As such, providing remote troubleshooting, advice, or support for printer repairs has its limitations.

We offer an in-person evaluation and repair service through our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Given our first-come, first-served policy, there might be a wait time before we can attend to your printer, should you decide to utilize our services. Our aim is to either repair the printer in its entirety or address specific issues as per your needs, with detailed guidance on how to proceed with either mail-in or local drop-off options.

While we strive to provide an affordable service, we understand that our rates might not fit everyone's budget. As such, we encourage seeking out self-help options through online research. Our YouTube channel, in particular, offers a wealth of information and tutorials that could help resolve your issue. The search function next to the "About" section could direct you to specific topics of interest. Given the vast amount of content produced over the years, it's likely you'll find something relevant to your problem. Furthermore, YouTube's recommendation system may also suggest useful videos from other content creators.

Thank you once again for reaching out with your concern. We're here to support you in finding a resolution to your printer issue and are ready to assist further should you need it.
