I have a new MF733Cdw, and I have been trying to darken printed text.
I've tried changing the toner density from the printer's control panel, Windows' printer settings (Windows 10), the Canon Remote UI, and within individual applications (Microsoft Word and others). I've made sure that toner saver is off, that I have the latest drivers, and that the latest firmware is installed.
I've tried adjusting only the black, adjusting black plus all three colors at the same time, and adjusting the main colors plus all three "fine adjust" densities at once. The path I'm using is <printer> <properties> <default settings> <quality> <general> <advanced settings> <toner density> <adjust> .
Nothing changes on the printed page. Setting density to +8 and to -8 yield the same results as 0.
What am I doing wrong? Is the printer malfunctioning?
