Abstract

There is disclosed a printer including a print head and a mounting assembly for a web roll having a core. The mounting assembly can center-justify the roll with respect to the print head. The roll can be loaded simply by pushing the roll slidably onto the mounting assembly and unloaded by pulling the roll or its core slidably off the mounting assembly using one hand. In some embodiments, there is no need separately to undo any latch or to free the roll or its core from any latch other than by pushing or pulling on the roll or the core. In another embodiment, one of the stops is pivoted either to trap the core between the one stop and another stop or to enable the core to be slid onto the support to a position between the stops or to be slid off the support.

Dependent claims

A mounting assembly, comprising:

a cantilevered support having an inner end portion and an outer end portion, the support being slotted and capable of slidably receiving and mounting a core with internal projections for web material,
a threadable first stop at the inner end portion,
a second stop at the outer end portion, having a deflector and threaded portion, the deflector cantilevered to the threaded portion and removable,
wherein the second stop is deflectable and includes a first engageable surface, the core being positionable between and in contact with the first stop and the first engageable surface of the second stop, and wherein the core cooperates with the first engageable surface to operatively deflect the second stop in response to an action of sliding the core off the support;
an axially extending shaft within the support and having oppositely threaded portions, and
wherein the first stop and second stop automatically adjust on the axially extending shaft and the first and second stops remain stationary in response to an action of sliding the core off the support and sliding the core onto the support.
