A:Answer Hello Ruby. The WF-3820 can print from a USB drive. USB 3.0 is not supported, and the drive can be up to 2TB in size and formatted in FAT, FAT32, or exFAT. The ADF can hold approximately 35 sheets of 8.5" x 11" sized plain paper, and the paper cassette can hold up to 250 sheets of plain paper. The machine can Automatically print and copy two sides. Unfortunately, 2-sided scanning must be done manually. Regards, Kevin - The Epson Team.
