Here are the steps to remove your print bed with a flat edged tool, such as a putty knife if your print bed is stuck. To get the print bed out, you will need to use more force than normal because the print bed is slightly thicker than normal, hence the reason why it can be difficult to remove.
Insert the tool on the front side of the print bed and then push the print bed backwards to unlock it. The second image (white printer) shows how to use the extruder front cover to push the bed backwards.
Lift the print bed up with the tool. The second image (white printer) shows the exact same motion, but using the extruder's front cover as the tool instead.
Grab and remove the print bed from the printer.
