Canon Cartridge 045 Black Toner for Color imageCLASS

The Canon Genuine Toner Cartridge 045 Black is the OEM consumable designed for Canon's Color imageCLASS MF634Cdw, MF632Cdw, and LBP612Cdw laser printers. At its core, the 045 is a single-cartridge system — toner and drum are housed in one unit, which simplifies the replacement cycle but means the drum is refreshed every 1,400 pages at standard ISO/IEC coverage. Canon engineers the toner formulation to work precisely with these printers' fusing temperatures and transfer voltages, which translates to consistent black density, sharp fine text, and reliable performance across the cartridge's full rated life without the mid-cartridge fade sometimes seen with off-brand alternatives.

The Cartridge 045 Black is positioned for small office and workgroup environments where print volume is moderate and print quality consistency matters more than absolute cost-per-page minimization. The 1,400-sheet standard yield is appropriate for light-to-moderate print workloads; offices printing above that threshold regularly should evaluate the 045 High Capacity variant at 2,800 sheets for a meaningfully lower cost-per-page. The 1.3-pound cartridge installs in a straightforward single-step process and is recognized immediately by the printer's firmware without error prompts — a practical advantage in environments where IT support for printer issues is limited.
