TKK 0 Posted February 20, 2022 (edited) WF 3620 series was sold in the U.S. at the office supply chain Staples.. Do you have a chipless solution or firmware downgrade for this model? It refuses to recognize most ink cartridges. Thanks for any info. Edited February 20, 2022 by TKK Quote Share this post Link to post Share on other sites
