The WorkForce 635 features a 4 color inkjet printer combined with a high resolution scanner featuring an ADF (automatic document feeder). The unit also has fax abilities, memory card printing, and convenient copy functions. Altogether the Epson WorkForce 635 is designed to print/scan/copy/fax all using the one neatly designed device. The speed of ink-jet printers, or lack thereof, has given most users headaches waiting for pages to creep out from under the hood of the printer. Many users resulted to ‘draft’ modes to shorten printing time as the loss of print quality. Printing in many offices is strictly black and white mostly for the time savings benefits, and the astronomical added costs of color inks! Epson has produced the desktop ink-jet all-in-one magician, capable of print tasks big and small at quicker speeds that users will appreciate. As you can see in the specifications from Epson, this beast is fully loaded and ready for your next major printing project.
