The Canon C-EXV 49 is a replacement drum unit designed to maintain high-quality print output for professional office environments. This component is essential for the imaging process, offering a substantial page yield of 75,000 pages based on standard A4 documents with 5% coverage, which helps reduce the frequency of maintenance intervals in busy workplaces. It is engineered for compatibility with a wide range of Canon imageRUNNER Advance systems, including the iR C3320, C3325, C3330, C3520, C3525, and C3530 models, as well as the imageRUNNER Advance DX C37xx and C38xx series, such as the C3822i, C3826i, C3830i, and C3835i. Since these printers utilize a four-color system, you will need one of these units for each color—black, cyan, magenta, and yellow—to keep your device fully operational.
