Dark you mean black hold the paper or just like fog.
If the page with black (only black without image) may be your bias have problem, just checking the bias its include transfer, primary changer.
If just like fog may be your problem at toner as Canon.Tech said. and 1000% some once replace toner without genuine Canon toner will be fog.

Normal time it is good. Dark background is coming only when I use to light or dark the content.
