Abstract: A spindle assembly capable of accommodating paper rolls of varying sizes is provided. The spindle assembly comprises a spindle arm adapted to be connected to a printer mechanism. The spindle arm comprises a first flange surrounding an opening. A spindle is provided for accepting a first paper roll. A first end of the spindle is fixed in the opening of the spindle arm. The spindle comprises a second flange arranged at a second end of the spindle. A sleeve is provided which is adapted to slide over the spindle and attach to the spindle arm for accepting a second paper roll. The second paper roll has a different size than the first paper roll. A printer having such a spindle assembly is provided, as is a method for accommodating different sized paper rolls in a printer.

Abstract: A cutter mechanism for a printer is provided. The cutter mechanism comprises a rotary cutter and a straight blade assembly. The rotary cutter may be mounted for rotation about a rotation axis and for translation across at least a portion of a width of a paper path perpendicular to the rotation axis. The straight blade assembly may be mounted for rotation about a shaft and adapted to cooperate with the rotary cutter. The straight blade assembly comprises a straight blade extending across the width of the paper path. A printer mechanism cover is mounted coaxially on the shaft so as to be movable between a closed position and an open position. A portion of the cover may impact the straight blade assembly when the cover is moved from the closed position to the open position, causing the straight blade to be moved away from the rotary cutter.

Abstract: A paper bucket for a printer with a self-adjusting spindle mechanism capable of accommodating media rolls of varying width is provided, together with a printer having such a paper bucket and corresponding method. The adjustable paper bucket may have a bucket frame and oppositely disposed wall assemblies pivotally mounted in the bucket frame. The adjustable paper bucket may further include oppositely disposed vertical flanges, each of the vertical flanges being pivotally mounted to a respective one of the wall assemblies. A spindle flange is rotatably mounted to each vertical flange for accepting a media roll therebetween. A motion linkage connects the wall assemblies together such that a movement of one of the wall assemblies results in an equal and opposite movement of the other one of the wall assemblies.
