Abstract: A printer is described herein that is equipped to internally remove the backings off of self-adhesive label paper, exposing an adhesive layer when ejected from the printer. A user desiring to print some sort of indicia on the self-adhesive paper need only initiate printing, and a label with exposed adhesive is ejected from the printer. A print side of the paper is split from a backing inside the printer pulling preceding print sides and backings at certain tensions, thereby creating a particularly effective separation angle. A ribbon break shaft and one or more rollers create the correct tension in the print sides, while a platen roller and cantilever leaf spring create the correct tension in the backings. In some embodiments, the optimal separation angle lies between 19 and 25 degrees.

Abstract: An apparatus and method that operates a stripper finger. The apparatus can include a media path configured to transport a media sheet. The apparatus can include a rotational member configured to contact the media sheet. The apparatus can include a stripper finger having a length along a longitudinal axis. The stripper finger can include tip at an end of the length. The stripper finger can be configured to selectively engage and disengage contact between the tip and the rotational member to selectively strip the media sheet from the rotational member.

Abstract: Apparatuses useful for printing and methods of stripping media from surfaces in apparatuses useful for printing are provided. An exemplary embodiment of an apparatus useful for printing includes a first roll, a belt including an inner surface and an outer surface, the first roll and the outer surface of the belt forming a nip, and a stripping member located internal to the belt. The stripping member includes a first needle bearing, wherein the first needle bearing contacts with the inner surface of the belt to facilitate stripping of media fed to the nip from the outer surface of the belt.

Abstract: There is disclosed a printer with an arrangement for assuring that a linerless tacky adhesive-backed web is reliably fed. The printer has stripper elements which terminate at tip portions which extend into the platen roll to initially cut grooves in the platen roll, and because the tip portions extend below the outer periphery of the platen roll into these grooves, the stripper elements continue to strip the web reliably from the platen roll during subsequent printing cycles.

Abstract: A removing claw 164 has a width W1 in a cross direction of 5 [mm] and a rectangular cross section with a height reduced toward a tip, and both ends of an upper side of the rectangle are chamfered to have a chamfered portion with a radius of r=1 [mm]. Consequently, a contact area of a toner sheet with the removing claw 164 is large. Therefore, a face pressure of a surface of the removing claw 164 where the toner sheet is to be delivered is reduced. Accordingly, the toner sheet can be delivered while being removed by the removing claw 164 without a material thereof rubbed and shaved by the surface of the removing claw and shaved by both ends of the upper side of the removing claw 164 even if the toner sheet comes in contact with the removing claw.

Abstract: A portable printer comprising a door pivotally coupled to a main body of the portable printer at a back end, a printing medium roller support rotatably mounted on the door of the portable printer, a platen rotatably positioned at a front end of the door, a door locking mechanism having a pair of door locking latches respectively positioned at opposite ends of the platen, a roller movably and rotatably coupled to the door locking mechanism and positioned parallel to the platen, a pair of levers movably coupled to the door locking mechanism for pressing the roller against the platen when the door is closed to the main body, a support frame positioned within the main body, a print head pivotally coupled to the support frame, a pair of coil springs coupled between the print head and the support frame such that the print head is essentially floating against the support frame, a body locking mechanism having a pair of body locking latches for latching with respective door locking latches, a gear system coupled to t

Abstract: A thermal printer in which a sheet of recording paper is held by and between a thermal print head includes a plurality of heat generating elements and a platen drum, the amounts of heat of the heat generating elements are selectively changed, and an image is printed onto the recording paper. In the thermal printer, a printing position is set just behind a clamp position at which a clamp clamps the leading end of the recording paper onto the platen drum. Therefore, the image printing can be started immediately after the clamp position passes through the thermal head, with the recording paper being in part wound around the platen drum by the thermal printer. As a result, the time taken from paper feeding to printing starting can be reduced.

Abstract: A paper cassette used in a printer for holding sheets of paper. The cassette comprises a case holding sheets of paper and corner claws mounted at both sides of the front end of this case. The claws engage the front ends of the corners of the uppermost sheet of paper. The claws have front walls which are inclined upwardly toward the direction in which the uppermost sheet is fed. The front walls are also inclined from the front end of the uppermost toward the direction in which the walls are distant from the front end of the sheet by slow degrees toward the inside of the widthwise of the sheet. When the uppermost sheet is curled, the corners of the front end of the sheet are disengaged from the corner claws certainly.

Abstract: A sheet feed device applicable to a recorder such as an ink jet printer or a thermal printer has feed rollers mounted on the same shaft in a spaced relationship and platen blocks mounted in spaces between the feed rollers. A sheet fed along the feed rollers is conveyed to the platen blocks by a feed force of the feed rollers.

Abstract: A printing apparatus including a feed path for print medium to be imprinted. A printing station defined by a printhead that is biased towards abutting contact with a platen roller. A floating mount pivotally mounts the printhead with respect to the platen roller so that a uniform contact pressure is established between the printhead and print medium during printing. The printhead is also mounted for pivotal movement about an axis transverse to the first axis which allows the printhead to move towards and away from the platen roller to facilitate loading of the print medium. A printhead sensor monitors the position of the head and automatically deactivates the printhead when it is about to be, or is separated, from the platen roller. A stripper mechanism is provided for automatically stripping a backing from the print medium and includes a stripper assist bar that causes the backing to follow, and frictionally engage, a peripheral region on the platen roller that is at least 90.degree..

Abstract: An ink jet printer includes a rotatable support for supporting a sheet of paper. The support defines an interior vacuum chamber and a plurality of vacuum openings in the surface thereof which communicate with the vacuum chamber. A rotary drive rotates the support and a vacuum source is provided for partially evacuating the vacuum chamber. A paper supply adjacent the rotatable support, loads a sheet of paper onto the rotatable support. An ink jet print head is mounted adjacent the rotatable support for printing on a sheet of paper supported thereon. A sheet diverter is positioned adjacent the rotatable support between the ink jet print head and the paper supply for stripping sheets of paper from the rotatable support when the sheets are not firmly supported thereon. A paper sensor is mounted adjacent the rotatable support, intermediate the sheet diverter and the ink jet print head, for inhibiting operation of the ink jet print head when a sheet of paper is diverted by the paper diverter.
