Canon Genuine Toner produces high-quality, monochrome and color output for all your home and office needs, that you can be proud of. Look for the Canon Logo and the Canon hologram, which should shimmer when moved back and forth. Don’t be fooled by imitators. Use of non-canon toner cartridges or refilled toner cartridges can cause damage to your printer and may affect the limited warranty for the product. High-capacity toner options help you printing longer, which helps limit replacements. For use with LBP674Cdw, MF753Cdw, MF751Cdw laser printers. Black: yields up to 2,100 pages / Cyan, Magenta, Yellow: yields up to 1,900 pages each (ISO / IEC Standard).
