Despite their compact sizes, Canon PIXMA printers offer 2-way paper feeding — from the paper cassette at the front and from an auto sheet feeder at the rear — and automatic duplex printing. Only available as options previously, these features have become standard thanks to the development of a simple U-turn Path. This configuration allows paper that enters from the front cassette to come back out the front after making a U-turn inside the printer. The path is shared with the paper feed mechanism for duplex printing to help achieve smaller dimensions for the paper handling mechanism and printer unit. Canon also developed original tools to find and simulate the ideal transport route based on elaborate studies of paper movement, transport resistance, curvature, materials, and motor control. This technology enables doublesided and borderless printing without damaging the photo paper surface.
