Canon imageCLASS MF746Cx Toner Cartridges
Your Canon imageCLASS MF746Cx uses the CART055 / CART055H toner series. This four-colour laser system is built for small business environments where professional document speed is non-negotiable. Because this printer handles both internal administrative tasks and external marketing collateral, we often see users depleting the high-yield black toner significantly faster than the colour units. To maintain consistent uptime, most office managers transition to the high-capacity "H" variants, which offer a more stable maintenance cycle and fewer interruptions during large print runs.
Choosing between genuine and compatible options
For businesses looking to manage overheads, we provide both genuine Canon and high-quality compatible CART055H cartridges. Our compatible range offers a cost-effective alternative for high-volume document printing without sacrificing the clarity required for business correspondence. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. For more information on how these options compare, you can read our guide on genuine vs compatible cartridges.
Understanding page output and replacement cycles
The yield for this series is measured using the ISO/IEC 19798 standard for colour laser printers. This provides a baseline for comparing the standard CART055 against the high-yield CART055H. In a typical small business setting, the high-yield "H" series is the preferred choice as it more than doubles the page capacity for black text and nearly triples it for colour. This is particularly beneficial for the MF746Cx, as it reduces the frequency of physical interactions with the printer's internal carriage.

Pro Tip
The imageCLASS MF746Cx is highly sensitive to toner density settings. If you find yourself replacing colour cartridges too frequently but only print "black and white" documents, ensure your printer driver is set to "Mono" or "Grayscale" as the default. Many "Auto" settings still use a small amount of colour toner to sharpen black text, which can lead to unexpected colour depletion.
Frequently Asked Questions
Can I mix a high-yield CART055H black cartridge with standard CART055 colour cartridges?
Yes, the standard and high-yield versions are designed to be interchangeable. You can use any combination of "H" and standard cartridges in the four slots. Most users upgrade the black to high-yield first while keeping the colours standard until their usage patterns justify the larger capacity.
Why does my MF746Cx show a "toner low```" message even though I only print in black?
Laser printers like the MF746Cx perform periodic calibration cycles to ensure the transfer belt and drums are correctly aligned. These cycles consume a minute amount of colour toner even if no colour appears on your printed page. If your colour cartridges are completely empty, the printer may stop functioning to protect the imaging components.
How do CART055H compatible cartridges handle fine text compared to genuine Canon?
Our compatibles use premium pulverised toner that mimics the melting point and particle size of the genuine Canon CART055H series. This ensures that even at the high speeds the MF746Cx is capable of, fine 6pt or 8pt fonts remain crisp and legible without the "ghosting" or "blurring" often associated with inferior generic toners.
