The Canon AQ1 is a cassette feeding unit designed to expand the paper handling capabilities of the imageRUNNER ADVANCE DX C5800 series. By adding two additional paper drawers to your printer, this unit significantly reduces the need for manual paper switching during large print jobs. It provides a total capacity of 1,100 sheets when using standard 80 gsm paper, supporting a wide range of media weights from 52 to 256 gsm. This flexibility allows you to keep different stocks on hand, including larger A3 formats, making it a practical choice for busy office environments where high-volume printing and diverse document sizes are common.
