Dual-roller overdriven peel mechanism

The present invention relates generally to an image forming device and more particularly to a printer having a dual-roller overdriven peel mechanism for peeling a protective backing of a label roll from labels attached to the protective backing. An imaging forming device using a platen, an upper peel roller, a lower peel roller movably positioned under and parallel to the upper peel roller, a diverter bar rotatably positioned underneath the platen and near the upper and lower peel rollers and adapted to guide a printable medium backing to move between the platen and the upper peel roller to between the upper and lower peel rollers, a peel bar rotatably positioned over the upper peel roller, a pair of lever cams rotatably positioned respectively at opposite ends of the upper and lower peel rollers, the lever cams are adapted to push the lower peel roller to press the printable medium backing against the upper peel roller during operation for moving the printable medium backing through the imaging forming device and to allow the lower peel roller to separate apart from the upper peel roller when the imaging forming device is open for loading the printable medium backing in between the upper and lower rollers.
