Patent ID: 6921222

Claim:
A high-speed printer comprising: a feedback control system for receiving a sheet of media, wherein said feedback control system is to detect a slack position of said sheet of media; a media assembly for supporting a media roll for supplying said sheet of media to said feedback control system, wherein said media assembly is to control a flow rate of said sheet of media based on said slack position of said sheet of media; and a roller system for receiving said sheet of media from said feedback control system, wherein said roller system is to feed said sheet of media to a print carriage, wherein the feedback control system further comprises a tensioner having a first end and a second end, wherein said first end is pivotably coupled to a base of said printer and wherein said second end is coupled to the sheet of media, wherein said tensioner is pivotable to move said second end and the sheet of media to the slack position, and wherein the feedback control system further comprises: a codewheel coupled to the first end of the tensioner, wherein said codewheel comprises a first lowered marking, a neutral marking, and a first raised marking, wherein said codewheel and said first lowered marking, said neutral marking, and said first raised marking are to rotate when the tensioner is pivoted; and a sensor coupled to the base, wherein said sensor detects the first lowered marking when the slack position of said sheet of media is a first lowered position, wherein said sensor detects the neutral marking when the slack position is a neutral position, and wherein said sensor detects the first raised marking when the slack position is a first raised position.
