When troubleshooting the Epson SC-F2100, users may encounter error 400, indicating a problem with the Circulation Pump Assy. A printer owner recently shared their experience trying to resolve this error. After purchasing an Epson SC-F2100 second-hand with only 1463 prints, the error 400 message appeared, suggesting an issue with the circulation pump. This article explores the steps taken to resolve the issue and discusses potential solutions.

Understanding the Error 400 Code

Error 400 on the Epson SC-F2100 typically indicates an issue with the Circulation Pump Assy. According to the printer's manual, this message is expected to occur when the printer has approximately 495,000 prints. However, the user's printer had only 1463 prints, prompting them to seek assistance from Epson technical support. The response from Epson indicated that the machine, being 5 years old, required a part replacement at a cost of €1500.

Purchasing the Service Program

To investigate further, the user purchased the Service Program for the SC-F2100. This software allows users to diagnose and resolve issues by accessing the printer's internal data. However, upon reviewing the program's manual, the user noted that the error message might not relate to the number of prints, hours, or minutes. Seeking clarity, the user contacted Epson but received no response.

Investigating the NVRAM File

As part of their troubleshooting, the user attempted to reset the counter using the Service Program. The manual provided guidance on how to view the printer's NVRAM (non-volatile random-access memory) data, which contains critical information about the printer's usage and status. Following the instructions on page 212, the user searched for the Display Info button in the Service Program, but it was missing.

The user also attempted to use the SC-F2000 Service Program to view the NVRAM file generated by the SC-F2100 program. However, this approach did not yield the expected results, as the Display Info option was not available. Without the ability to view the NVRAM data, the user couldn't determine if the printer required additional maintenance or if other components were approaching expiration.

Seeking Solutions and Community Support

Given the lack of response from Epson and the inability to interpret the NVRAM data, the user is seeking guidance from the community. The ultimate goal is to avoid unnecessary expenses and understand why the error message appeared when the printer had only 1463 prints.
