The Epson WorkForce WF-3640 printer uses four individual ink cartridges:

Black: This is usually labeled as “Black” or “BK.” It is used for printing black text and graphics.

Cyan: This is the cyan ink cartridge, often labeled as “Cyan” or “C.”

Magenta: This is the magenta ink cartridge, typically labeled as “Magenta” or “M.”

Yellow: This is the yellow ink cartridge, usually labeled as “Yellow” or “Y.”

These cartridges can be replaced individually as they run out, which can be more cost-effective than replacing a combined color cartridge.

When purchasing replacement ink cartridges for your Epson WorkForce WF-3640 printer, make sure to get cartridges that are compatible with your specific printer model. You can usually find this information in the printer's user manual or on the Epson website. Additionally, ensure that you are purchasing genuine Epson cartridges or high-quality third-party cartridges that are compatible with your printer to ensure optimal performance and print quality.
