Welcome to our Canon Forum!
The "Low Cartridge Level" message on your Color imageCLASS MF743Cdw notifies you that a toner cartridge needs to be replaced soon. This message allows you to make sure that you have a replacement toner cartridge ready. We suggest you replace the toner cartridge if you see this message before you start to print a large job.
You can specify to continue printing using the printer's operation panel when the amount remaining in the toner cartridges is low using the process below:
<Menu> -> <Preferences> -> <Display Settings> -> <Action When Warning> -> <Low Cartridge Level> -> Select <Continue Printing> -> <Apply> -> <Yes> ->HOME
You can also set the Color mode to black and white:
<Menu> -> <Function Settings> -> <Printer> -> <Printer Settings> -> <Color Mode> -> Select <Black & White> -> HOME
