Frequently Asked Questions
How do I know when a specific CART418 colour toner is running low on the MF729Cx?
The printer control panel displays individual status levels for CART418BK, CART418C, CART418M, and CART418Y. You can continue monochrome printing even if a colour toner is depleted by adjusting your print driver settings to black and white mode.
Why does the CART418BK Black cartridge have a higher page yield than the colour cartridges?
Standard document workflows contain significantly more black text than colour graphics. Canon designs the CART418BK with a 3,400-page capacity to balance replacement intervals alongside the 2,900-page CART418 colour cartridges.
Are all four CART418 toner cartridges required for the printer to operate?
Yes, the Canon imageCLASS MF729Cx requires all four CART418 cartridges (Black, Cyan, Magenta, Yellow) installed in the carousel to initialise and perform routine self-calibration cycles.
