You have right. With machine powered on, open the front cover and pull out the old toner cartridge, shake well the new toner and put in place.
A few mounth ago i bought a Phaser 7800 and now i have to change the first toner (cyan)
I know it's a stupid question ... but I did not find anything in the user manual.
How to change the toner?
just open the front door and change the toner?
should the printer be turned on or off?
