Why is My EC-C7000 Printer Not Recognizing the New Magenta Cartridge? Troubleshooting Tips!

Question:

One customer needed to replace the magenta cartridge on their EC-C7000 printer. When they did, a little metal piece came out with the old cartridge. Now, the printer can’t recognize the new OEM magenta. They're asking, "Where does this metal piece go?" and "Do we have a service manual for the EC-C7000 printer?"

Answer:

The metal piece in your EC-C7000 printer

That tiny bit of metal is a brass contact to the CSIC (Contact Serial Interface Chip), which is crucial for your printer and cartridge to communicate. This black metal part unlocks the code, typically from the 9-pin CSIC chip on your EC-C7000.

For those who want to go to an automotive CSIC, you would use the 9-pin CSIC chip, which we have available at the link to the site: 9-Pin Epson Cartridge Chip Board [https://bchtechnologies.com/products/one-epson-cartridge-chip-board-pins-9-pin].

What Should You Do?

Replace the Brass Pin: If the contact brass came out in one piece, insert it gently back into the assembly. This component is crucial for the printer to recognize the cartridge, so it must fit snuggly. You may need to pull the assembly and carefully shove the contact back under it.

Bent Brass Pin: If you bend the bronze pin while touching it, you can exchange it. We do not have a service manual for the EC-C7000 model; however, we do supply parts. You can buy a replacement old 9-pin CSIC chip from us here: 9-Pin Replacement Chip [https://bchtechnologies.com/products/one-epson-cartridge-chip-board-pins-9-pin].

OEM Cartridge Compatibility: Once you have seated the brass contact back down into the assembly, the printer should be able to install and recognize the new OEM magenta cartridge.

Troubleshooting Tips:

• Power Off/On: If the printer still does not detect the cartridge after inserting it, turn off the printer and turn it back on. This may help reset your printer's recognition process.
• Clear the Contact Region: If the problem remains, gently clean the brass contact area with a soft cloth to ensure no dirt or residue disrupts the connection.
• Check for errors: If your printer displays error messages (such as “Cartridge Not Recognized”), this might indicate a problem with the chip contact or connection. You may even have to reset the chip or replace the cartridge altogether.
