IMAGING MODULE FOR HOT MELT WAX INK JET PRINTER

摘要

An imaging module includes an ink jet print head for printing human-readable or coded (e.g., bar code) information directly onto various porous and non-porous materials (e.g., a corrugated cardboard container), and a pair of reservoirs that hold the melted ink ultimately used in the printing process. The module also includes an ink feed hopper into which one or more solid sticks of hot melt wax ink are fed and an associated heater to melt the ink sticks in limited volume, together with associated vents, control pumps and valves, all integrated together within the imaging module to deliver the melted ink to the print head for printing on a container or other items.
