By installing an authentic Canon drum component, you ensure perfect factory-specified surface sensitivity and seamless integration with your press's internal developing stations. Delivering an impressive estimated yield of up to 600,000 pages for monochrome output and 420,000 pages for color impressions, this highly durable production part minimizes maintenance downtime and ensures consistent gallery-quality output from the first sheet to the last.
