This is a quick setup guide for Canon MFC-790CW, it includes instructions for product installation and usage.
The guide starts with unpacking the machine, removing protective tape, and connecting the power cord, telephone line, and supplied USB cable. It also explains how to set up a network connection using a Category 5 (or greater) straight‑through cable and warns about grounding requirements.
Next, it covers loading plain A4 paper, installing the four ink cartridges (LC990 series), running the initial cleaning cycle, and performing a print‑quality check. The guide finishes with instructions for choosing a receive mode, restoring network settings to factory defaults, and replacing consumables.
