Thank you for contacting us with this detailed question, and I apologize for any delay in our response. I understand that printer issues like these can be both pressing and complex, so I want to consider your question carefully. At BCH Technologies, we’re grateful for your engagement, primarily through our YouTube channel, which offers support and information on printer troubleshooting. Your feedback and questions play a significant role in enhancing our technical expertise.
Here's a step-by-step guide to address the simultaneous blinking of the paper and ink lights on your Epson L1800 (Punehod L1800) printer. This issue typically indicates a critical error, often called an “APG Error Reset.” Here’s how you can proceed with diagnosing and potentially resolving the problem:
  1. Confirm Printer Fatal Error Status:
    Simultaneous blinking of the paper and ink lights usually signals a fatal error. This error could be due to various internal issues, not just the encoder strip. Given that you’ve already cleaned accessible components, a deeper diagnostic approach is likely needed.
  2. Download the Epson Adjustment Program:
    To gain insight into the exact nature of this issue, you can use the Epson Adjustment Program, a utility designed to diagnose and provide detailed information on printer issues. This tool can sometimes be found on Epson’s support site or through licensed providers. Ensure you download it from a reliable source to avoid compatibility or security issues.
  3. Install and Run the Adjustment Program:
    • Install: Once the Epson Adjustment Program is downloaded, install it on a Windows-based computer (the software is unavailable for Mac OS).
    • Connect Printer: Attach your Epson L1800 printer to the computer via USB.
    • Run Program: Open the Adjustment Program and select the Epson L1800 printer.
  4. Access Printer Diagnostics:
    Within the program’s main interface, choose “Particular adjustment mode.” Then, find the “Printer Information Check” option. Click this to retrieve your printer’s recent error logs, typically including the last five recorded error codes.
  5. Review Error Codes and Interpret Findings:
    The program will display a list of recent error codes, with the most recent at the top. These codes can often clarify the underlying issue with your printer. Consult the Epson L1800 service manual to match the codes to potential solutions. Common issues might involve the carriage unit, sensor issues, or motor malfunctions, each of which may have specific solutions in the manual.
Following these steps will give you a clearer picture of the exact issue causing the APG error on your L1800 printer. Depending on what the error codes reveal, you can take more targeted steps toward repair. If it is indeed an APG error suck as 71H, I have a video here: https://youtu.be/G_lZLqRH_f0
 
Addressing printer issues can be complex, mainly due to the hands-on nature of troubleshooting. We cannot provide remote support for printer repairs but offer a local diagnostic and repair service (https://bchtechnologies.com/printer-repair-service) on a first-come, first-served basis. This service includes mail-in and drop-off options, with clear instructions for each. However, we understand our rates may be higher than other service providers, so we encourage you to explore self-help resources.
