How to Reset the “Replace Wiper” Error on Epson ST-C2100: A Detailed Guide

Question:

My Epson ST-C2100 printer displays a “Replace Wiper” message, but I don’t see a wiper part to replace. Can this error be reset?

Answer:

Understanding the “Replace Wiper” Message on the Epson ST-C2100

While uncommon, the “Replace Wiper” error message is essentially Epson’s way of notifying the user that the waste ink system—often involving the wiper blade and ink absorber pad—is due for maintenance. However, as you've observed, the ST-C2100 doesn't have a user-replaceable wiper blade like higher-end models might. This message is often tied to a waste ink counter stored in the printer's internal memory (EEPROM), not an actual sensor reading a physical wiper.

Can You Reset the “Replace Wiper” Message?

Yes—but it’s not always straightforward.

Standard Reset Tools (If Compatible)

For many Epson models, you can reset the waste ink counter using one of these tools:

• InkChip Resetter (https://inkchip.net)

• WIC Reset Utility (https://www.wic.support)

These tools allow you to clear the error without hardware disassembly. However, compatibility with the Epson ST-C2100 (C2100 or ST models) may be limited. These programs are often designed for more mainstream printers, and new or regional variants may not be supported.

Advanced Reset Options (For Unsupported Models)

If standard tools don't work, there are two advanced paths—both requiring significant technical knowledge:

1. EEPROM Programming with a Binary Dump

   • This involves removing the printer’s mainboard, accessing the EEPROM (memory chip), and flashing it with a new binary file that resets the waste ink counter.

   • You may need to desolder the EEPROM chip depending on your access points.

   • This is highly technical and not recommended unless you’re experienced with microelectronics and EEPROM flashing tools.

2. Using Open-Source Software for EEPROM Access

   • This method uses serial communication tools and custom scripts to access and modify the EEPROM values.

   • It involves comparing memory dumps from similar working printers to identify waste ink counter data.

   • This is also a trial-and-error approach and often requires C/C++ or Python programming, as well as knowledge of how Epson's protocol works.

In both of these advanced options, it’s fair to say you need to “know someone who knows someone.” These methods are often shared in tight-knit technical forums or repair communities and are not publicly supported by us. At BCH Technologies, we can point you in the right direction, but due to the legal and practical risks, we do not provide guidance on EEPROM programming or circumventing firmware restrictions.

Repair & Support Options

Resolving firmware-level messages like "Replace Wiper" often requires in-person inspection or programming tools that can’t be deployed remotely. Because of the hands-on nature of these repairs, we are unable to offer direct support or remote troubleshooting for this issue. However, we do offer an in-person evaluation and repair service through our local diagnostic facility, which you can learn more about on our printer repair service page (https://bchtechnologies.com/printer-repair-service).

We operate on a first-come, first-served basis due to high demand, and wait times may be a few weeks. Our services cover both full printer repair and component-level work, depending on what your issue requires. We are transparent about the fact that our services aren’t always the cheapest, which is why we highly encourage users to try self-research and repair first if comfortable doing so.
