How to Troubleshoot Epson Error Code 100016: Scanner Failure Explained

Question:

Printer error code 100016: I have seen many of your videos/a few of them to try and sort this but I had no success. It began when my screwdriver slipped and the entire top of this printer came off, yanking a couple tiny plugs out along with it. The technician assisted me to assemble it back but now the printer throws this error and is giving a different noise. Please would you help to tell me what is wrong and how can I solve this?

Thank you for reaching out to us! We at BCH Technologies appreciate your engagement and support, particularly with regard to our YouTube channel (https://youtube.com/@bchtechnologies). Your feedback plays a crucial role in further developing our technical expertise, and we’re happy to assist you with this problem.

Regarding the issue you’re facing with error code 100016 on your Epson printer, this error is specifically related to the scanner unit. According to Epson, error 100016 means:

• HP Detection Failure
• CIS Unit Failure
• Scanner Housing Upper or Lower Failure
• Scanner Motor Failure
• Foreign Object Obstruction
• Main Board Failure

Based on your description, there’s a strong possibility that when the printer top fell, it may have dislodged or damaged a component connected to the scanner, such as the scanner motor or the CIS unit (Contact Image Sensor). These components are responsible for controlling the scanner's movement and detecting its position, so a hard impact could cause the system to malfunction, resulting in the error you’re seeing.

Here are a few steps you can take to troubleshoot:

1. Check for Loose Cables and Connections:
   Since you mentioned that two smaller plugs were pulled out, it's possible that they weren't reconnected properly or fully. Double-check all the connections, especially those related to the scanner unit. Make sure everything is securely plugged in.

2. Inspect the Scanner for Obstructions:
   Sometimes, a foreign object can get lodged in the scanner housing, preventing the scanner from functioning correctly. Open up the scanner section carefully and check for any objects or debris that might be causing the issue. Here is a video of how:

3. Examine the Scanner Motor:
   The strange sound you're hearing could indicate that the scanner motor is struggling to move or is malfunctioning. The motor might have been damaged during the incident, causing the printer to throw the 100016 error. If the motor seems faulty, replacing or repairing this part could resolve the problem.

4. Main Board or CIS Unit Failure:
   If none of the above solutions work, the issue may lie deeper, such as a CIS unit failure or a problem with the main board. These components can be tricky to diagnose without professional tools. In such cases, you might need to consider replacing the mainboard or reaching out for professional help.
