Abstract
In a thermal printing system having an automatic paper feeding mechanism paper may be misfed and become crumpled between one of a pair of spring biased pinch rollers and the platen of the printing machine. A mechanism is provided for automatically releasing pressure between the rollers and the platen, wherein a depression/release lever is provided with a cam disposed between supporting members of the pinch rollers, and the lever is actuated when a frame of the printing machine is raised to provide access to the machine, causing the cam to widen the space between the pinch rollers and the platen so that the crumpled paper can be easily removed.
