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 system and method for advancing sticky media through printers includes one or more feed rollers comprised of a grit roller. The grit roller contacts an adhesive side of liner-less label stock removed from a roll or stack for printing. The grit roller works cooperatively with an opposing, counter-rotating roller to remove the label stock from the roll and feed it to a printer.

A paper separating roller, including a shaft body, a first friction member and a second friction member is provided. The first friction member covers a first surface of an outer periphery of the shaft body. The second friction member covers a second surface of the outer periphery of the shaft body, wherein the first friction member and the second friction member are formed of two different materials. With the design of the friction members being formed of composite materials, the paper separating roller has the advantages of two different material features at the same time, such that a wider range of performance capabilities can be achieved.

A sheet transport roller having a high friction coefficient and a rubber composition for forming a roller main body thereof. The rubber composition of the present disclosure, which is a rubber composition for forming the roller main body of the sheet transport roller, contains a rubber component containing an ethylene-α-olefin copolymer and a rosin component.

Disclosed is a soft tube of a sheet conveying portion of a sheet conveying roller, including: a region with irregularities in an outer peripheral surface of the soft tube. The region has a root mean square slope Sdq within a range of 0.03 to 0.50.

A sheet conveyance apparatus includes a conveyance unit, a conveyance guide, a driven rotary member, and a support portion. The support portion supports a shaft portion of the rotary member driven to rotate by a sheet conveyed by the conveyance unit and guided by the conveyance guide. The support portion includes first and second contact portions that support the shaft portion of the driven rotary member while being in contact with the shaft portion. With respect to a cross section of the shaft portion perpendicular to an axial direction of the shaft portion, the driven rotary member is disposed so that a portion, of the driven rotary member, that is on a lower side in a vertical direction relative to a horizontal line and is on one side in a horizontal direction relative to a vertical line comes into contact with the sheet.

The transport path TR is a transport path TR for transporting the medium P in the transport direction, the transport path TR including path members XP that guide the medium P and that are arranged in the X-axis direction, which intersects the transport direction, wherein the path members XP are configured so that positions where the path members XP are provided are mutually switchable.

A paper feeding roll includes a shaft body and an elastic material layer. A first outer diameter portion and a second outer diameter portion having a larger outer diameter than the first outer diameter portion are provided in a portion where the elastic material layer is provided. A sloping portion is provided connecting between the first and second outer diameter portions so that the outer diameter varies along an axial direction. The sloping portion occupies 3% to 80% of the portion where the elastic material layer is provided. A difference in outer diameter between the first and second outer diameter portions is 50 μm to 1,000 μm. Protrusions that form surface unevenness are formed on an outer peripheral surface of the elastic material layer. Surface roughness of the first outer diameter portion is 50% to 200% of a step difference between the first and second outer diameter portions.

A system and method for feeding a ribbon of un-lined label stock to a printer includes first and second, abutting rollers that cooperatively remove label stock from a roll. An optical sensor is disposed in a ribbon path between the rollers and the printer. The optical sensor determines a slackness level of the ribbon between rollers and the printer. Speed of a drive roller drive motor is increased when the slackness level is below a prescribed threshold. Speed of the drive roller motor is decreased when the slackness level is above a prescribed threshold.
