Problem with Scanner Error after Firmware Update
Introduction
After updating the firmware to CV99Z9 an error appeared that displayed a Scanner Error message. The error occurred while scanning and prompted to turn off the power and turn it back on. If the error persists, it is recommended to contact Epson Support with the error code 100016.Troubleshooting
I returned the printer to the store where it was purchased, and they changed the scanner unit and the mainboard. However, after updating the firmware to CV14I9, the error reappeared. I reverted back to the original firmware version 17.64.CV09L3, which resolved the error. Please note that I had purchased a key in July 2021 with Order ID 22586459.Resolution
To resolve the error, please follow these steps:1. Flash the original CV04KC firmware version first.
2. Then flash the chipless CV14I9 version.
3. Use the License utility and your Activation Key after the firmware updates.
Continued Issue
Despite flashing the firmware to CV04KC and then to CV14I9, the error 100016 continued to appear. It seems that the new WF-C5700 printer, possibly from version CU10L3 of June 30, 2021, is not compatible with the existing Chipless firmware.Solution Implementation
I attempted to resolve the issue by flashing the firmware using both the update mode and normal mode, but the error persisted. It was suggested to use the updated CL09L3 version to potentially address the error.Community Support
