How to Clean the Inside of a Laser Printer

I have a canon imageclass laser printer. Is there any way to fix white spots coming out on my prints? It seems to be happening continuously. Random white dots coming out on every paper differently. (We're using heavy paper)

My hp 8550n and is printing poorly but i have no one to clean it. What can i do?

Simple tutorial to follow. No bs talking or introductions.

my brother dcp l2540 drum gren tube blake wahy

I cleaned the inside area after removing the toner cartridge (HP P2015d, btw) with isopropyl alcohol and a clean cloth. After replacing the toner cartridge, the printer won't print properly. Pages come out either completely blank or with just the faintest hint of the darkest text. Any suggestions to fix this?

This is the most thorough video on cleaning a laser printer I've seen yet. Thank you!

Use alcohol, but don't use a flammable liquid to clean with? Alcohol IS flammable.

My device keeps saying document scanner jam even though there's no paper jamming. It's Brother's DCP L2550dw series
