A modular printer having a media take-up assembly, a support block assembly, a printhead assembly, a stepper motor assembly and a display assembly is provided. A support housing having a plurality of recesses formed on an internal wall of the modular printer is also provided. Each of the recesses is configured to receive and align one of the modular printer assemblies with the other modular printer assemblies. Each of the assemblies is configured as a module which can be easily accessed and quickly secured to or detached from the support housing. The support housing is adapted to receive assembly modules for both thermal ink printers and ribbon ink printers such that the modular printer can be easily converted from one to the other.

A print media sensor mounting assembly includes a housing having a sensor mounting element. The sensor mounting element has a sensor position movably mounted therein for movement of the sensor position amongst a plurality of positions corresponding to a width of a print media web.

Adjustable sensor assembly for printers

A print media sensor mounting assembly includes a housing having a sensor mounting element. The sensor mounting element has a sensor position movably mounted therein for movement of the sensor position to a plurality of predetermined positions corresponding to a width of a print media web.

The present disclosure is directed to a media tracking guide mechanism for guiding the transport of printing media in a printing apparatus. The media tracking guide mechanism is designed to provide positive tracking to print media of various types passing through the guide as the print media is supplied to a printing apparatus. The print media tracking guide preferably includes a guide housing configured and dimensioned for mounting along a hub portion of a printing apparatus and an armature rotatably coupled to the guide housing. The guide housing includes a core member having a print media transport path along an outer peripheral portion thereof and an overhang support positioned in a spaced relationship from the core member. The overhang support includes a slotted area for receiving a lever component. The core member and overhang support are rigidly coupled to a flange portion along a common side thereof. The armature is coupled by a spring member and is equipped with a head member and associated lever component for selectively biasing the head member against the guide housing. Preferably, the head member includes a roller for providing tracking forces along the print media transport path of the core member. A method of providing positive tracking to print media utilizing the media tracking guide is also disclosed.

Media tracking guide

A media supply for a thermal ink printer, includes a central shaft defining a longitudinal axis, a media hub for supporting a supply of media in a coiled configuration coaxially mounted about the central shaft and adapted for rotational movement thereabout, a hub clamp mounted to the media hub and adapted for axial movement therealong to accommodate media supplies of various lengths and a torsion spring mounted about the central shaft and operatively engageable with the media hub to rotatably bias the media hub to an initial position corresponding to an unstressed condition of the torsion spring in response to movement of the media hub through a predetermined angular sector of rotation in one rotational direction, to thereby maintain a predetermined level of tension on the media. A locking member may be associated with the hub clamp to selectively secure the hub clamp at a predetermined axial position.
