Epson Workforce WF-3640, one of the most ground-breaking wireless all-in-one printers, produces fast, print-shop-quality colour prints and laser-sharp black and colour text, and is also cost-effective. It is multifaceted and innovative in its features and specifications. It offers multiple blue-chip features including high-speed print, auto double-sided print, copy, scan, and fax. In addition, it provides plus 35-page Auto Document Feeder, superior image quality on plain paper, two paper trays, and more. Despite offering bundles of surprising features, it also suffers from roadblocks in the form of Error Code 0xe5, which is confronted during the print job. There are several reasons behind this technical glitch but it can be fixed satisfactorily.
