Abstract
A tensioner and tensioning system for maintaining tension in a printer liner while providing manual advancement of the printer liner without accessing the inner compartment of the printer. A tension comprises first and second end brought in proximity to form a channel, and a middle portion formed into a circular configuration to hold the roll of printer liner. A stopper is included within the channel between the two ends which resists movement of the liner and promotes tension. The liner is preferably advances against the resistance of the tensioner by a take-up roller cooperating with a one-directional clutch which advances the liner without relaxation to maintain tension. The one-directional clutch is operated from an external area on the printer to enable the manual advancement of the liner without accessing the printer's inner compartment.
