Epson SureColor T3475 Cyan Cartridge Chip Recognition Error: Troubleshooting and Solutions

Question:
My Epson SureColor T3475 printer isn't recognizing the Cyan ink cartridge chip. I've inspected the cartridge chip board and suspect it might be misaligned or broken since the Cyan color isn't registering properly. All other colors (Yellow, Magenta, Black) seem to be working fine. Can you advise on what parts might be necessary and how to fix this issue?

Answer:

Upon reviewing the images you've provided, the pins on your Cyan cartridge chip board seem straight and intact, without noticeable bends or breaks. Typically, bent or damaged pins on the Cartridge Sensor Integrated Circuit (CSIC) are the most common reason for cartridges not being recognized. However, given your provided images, that doesn't appear to be the case here.

Considering the pins appear fine, the issue might lie elsewhere. First, I would recommend testing the Cyan slot with another functional cartridge. For instance, if inserting a known-good magenta cartridge into the Cyan slot results in the printer recognizing it correctly, the issue is likely with the Cyan cartridge chip itself rather than the board or pins. On the other hand, if the printer then misidentifies the color or still fails to recognize the cartridge, you may be experiencing a firmware-related issue.

Firmware issues can cause printers to incorrectly read cartridges due to software conflicts or updates designed to restrict cartridge compatibility. If this happens, consider updating or downgrading the firmware as a potential solution. Epson frequently releases firmware updates, and sometimes rolling back to an earlier firmware version can restore compatibility with certain cartridge chips.

If the problem persists even after verifying cartridge integrity and firmware adjustments, the issue may be the chip board itself, despite appearing undamaged. In this case, replacing the entire CSIC assembly or specifically the Cyan chip reader board would be necessary. You can usually obtain these parts from certified Epson parts suppliers or authorized service centers.
