A system (300) is provided having a printer (4) to print printing liquid onto a web (6) of media (8). The system (300) has a winding roller (10) on which to roll the web (6) of media (8) after printing. A tensioner (12) to vary the tension in a portion (14) of the web (6) of media (8) is also provided. The portion (14) is a portion of web which is being rolled onto the winding roller (10). Also provided is controller (16) to control the tensioner (12) to vary the tension based on the time taken for the printed printing liquid on the web (6) of media (8) to dry.

An image recording apparatus includes a pair of conveying rollers configured to convey a sheet in a conveying direction, a recording unit located downstream of the pair of conveying rollers in the conveying direction and configured to record an image on the sheet, a first side-guide located upstream of the pair of conveying rollers in the conveying direction and configured to come into contact with at least one of opposite ends of the sheet in a width direction orthogonal to the conveying direction. The first side-guide is movable in the width direction. The image recording apparatus further includes a second side-guide located downstream of the pair of conveying rollers and upstream of the recoding unit in the conveying direction, the second side-guide being configured to come into contact with at least one of opposite ends of the sheet in the width direction and movable in the width direction.

The invention provides a tape dispenser for liquid-activated tape which can be used in handheld or table-top modes. A main body of the dispenser has a rear section for holding a tape reel, and a front section which houses a drive section, a cutter, an activation section, and a main reservoir located below the activation section for holding liquid to activate the tape. A pump is arranged to pump liquid from the main reservoir to the activation section, where in use liquid is applied to the tape to activate it, and means are provided to allow liquid that overflows from the activation section to return to the main reservoir, preferably under gravity. The tape reel is supported by a drum in the rear section, and the drum can be slid out of the rear section to allow the tape reel to be replaced.

A cutter unit includes a first frame, a fixed blade, a movable blade, a movable blade drive mechanism and a pressure mechanism. The fixed blade has a first cutting edge portion. One end portion of the movable blade has one end configured to cut a cut item in cooperation with the first cutting edge portion. The second cutting edge portion and the first cutting edge portion contacting with each other at a first point and a second point. Another end portion of the movable blade has a contacting portion in contact with the first frame at a third point. The first point, the second point and the third point define an imaginary triangle. The pressure member presses the movable blade at a pressure contact position so that the movable blade presses against the fixed blade. The pressure contact position is positioned substantially within the imaginary triangle.
