Appendix A
This appendix describes the theory of operation for the 3600 printer.
Functional Description of the 3600 Mechanics
This section describes the basic mechanical functionality of the 3600 printer.
The 3600 printer has a sheet metal frame (base plate and main deck plate) to which mechanical and electrical components are attached. The printer holds, moves, routes for contact by the printhead, and stores label stock and ribbon by electronically controlled mechanical means. Sheet metal covers protect media and components.
The printer has one electrically powered motor that is the source of simultaneous movement for all of the driven parts. The motor shaft uses a pinion gear to impart drive force to the rotating parts, producing ribbon and liner movement.
The motor pinion gear drives the platen roller by meshing with the
The motor pinion gear also meshes with a
The liner takeup clutch/pulley rotates an idler shaft and gear that meshes with an identical gear on the liner takeup hub shaft to produce reverse rotation of the liner takeup hub.
The TTR drive function and the liner drive function each use
The clutch/pulley assemblies on the TTR takeup hub and liner reverse shaft are similarly color coded because they have different torque values. The springs inside are color coded as well: TTR = white gear, white pulley/clutch, white spring (inside); liner = black gear, black pulley/clutch, black spring.
