Canon does not sell non-consumable replacement parts for its consumer grade products. Purchase consumables such as ink and toner at authorized Canon retailers such as Staples, Quill and Fry's Electronics. Canon maintains a full and updated list of authorized dealers on its support website.
For professional-grade products, contact Canon to purchase replacement parts. Consumables for professional products are available online, over the phone or through an authorized dealer. Order internal replacement parts such as print heads by contacting Canon's parts ordering department. Updated web addresses and telephone numbers for these services are provided on Canon's support site.
Unauthorized third-party retailers such as PartsNow sell parts that are mechanically compatible with Canon printers but are not certified by Canon to work. Canon recommends against purchasing unauthorized parts. Using these parts may void the manufacturer's warranty of the printer. Always check parts vendors against Canon's list of authorized dealers and service providers if the printer's warranty status is a concern.
Canon recommends that all non-consumable service parts be installed by an authorized technician, including parts purchased directly from Canon. The company cannot guarantee product safety or correct operation when unauthorized parts are used or when authorized parts are installed by an unauthorized person.
