Whenever i give print command on my samsung scx4321ns printer it shows the msg rear door open how will i cure it.
I am only guessing at this point but there should be a tap that sticks out from the back of the rear door ( much like the way a microwave door has a tab on it that lets you know that the door is fully closed ) so check the back of your printer to make sure that the tab is still in place and if it is, check to see if it is doing what it was meant to do, also the tab system might have been replaced with a small magnet or a metal plate that makes contact with each other and when this is done the printer knows the door is closed, so if all looks good then it could be the electronic part that the tab or magnet comes into contact with and this is faulty or misaligned, remember to look closely at the back of the door to see if a tab has been broken off or is missing. So also study the printer body and look for a way in which the printer knows that the door might be open eg. some sort of electrical switch that tell the printer that the door is not shut and then ask yourself why the switch is not been activated.You might have to takes steps like gluing on a tab or wedging something in between the switch to trick the printer into thinking that the door is shut but a little bit of detective work is required on your behalf.
