Why does my printer keep clogging?

Episode 1633
Chris fromChris has bought 4 Epson printers, and the blue always stops printing after awhile. It keeps clogging, even though he prints a lot with it. Leo says that inkjet printers clog if you don't use them regularly. Leo says that if you're using official Epson ink, you shouldn't have a clog. But if you're buying your ink from Amazon, it's possible that you purchased counterfeit ink. So be sure you're buying your ink from an authorized Epson retailer. But it could also be a defect, so Leo advises contacting Epson directly.
