Hi all , went out to look at an old HP M712 printer that was randomly bending some corners , i went to take the fuser out , which is not complicated , as you release that latch from the left door and turn the two levers down 90 degrees inward and pull the fuser out. But for some reason the fuser will not come out , its just stuck in there Also now i have a " close left door " message.So wondering if anyone has ran into this kind of issue before. thanks
