Canon’s website (usa.canon.com) has manuals for both home and commercial office printers, as of 2015. The website provides an electronic or PDF version for each of its home office and commercial printing products.
To find the manual for a home office printer, visit the company’s website, and select the Consumer & Home Office button. Click Service & Support; then click the Manuals & Brochures tab. Enter the model number of the machine in the search field, or select model number from the provided list.
To find the manual for a commercial office printer, select the Office Equipment button from the Canon website homepage, and then click Support & Drivers. Once you have selected the product type, family and model, click the Brochures & Manuals button to access the user manual. The manuals for office printers are much larger and are available in both interactive online versions and downloadable ZIP files.
