Adjustable trimming assembly

An adjustable trimming assembly configured to receive printed media along a path, the printed media having a generally rectangular shape and comprising a first dimension, a first edge parallel to the direction of the first dimension, and a second dimension substantially perpendicular to the first dimension, the adjustable trimming assembly comprising:

• a stop configured to position the first edge of the printed media at a location along the path;
• a trimming device adapted to trim a margin from the second dimension of the printed media, the trimming device including a blade that is movable in unison with the printed media along the path while the margin is trimmed from the second dimension of the printed media;
• an endless drive mechanism coupled to the stop to adjust a distance between the stop and the trimming device in a direction substantially parallel with the path, wherein the endless drive mechanism comprises
• at least two pulleys,
• an endless drive member comprising the stop coupled thereto, the endless drive member extending between the at least two pulleys, and
• a motor operably coupled to one of the at least two pulleys to drive the one of the at least two pulleys;
• and
• a controller electrically interfaced with the motor for controlling adjustment of the distance between the stop and the trimming device, based on data associated with the second dimension of the printed media, for consecutively trimming a first piece of printed media received along the path to a first trim size and a second piece of printed media received along the path to a second trim size;
• wherein the controller is electrically interfaced with the motor for moving the stop between a first position to abut the first edge of the printed media moving along the path, and a second position displaced from the path of the printed media, and wherein the endless drive member is rotatable by the motor to rotate the stop downwardly and away from the path when moving the stop from the first position to the second position.
