Problems solved by technology
the non-planar profile of the ink supply path opening around the heater (such as raised or depressed areas) can result in poor bonding or adhesion between the heater and adjacent tank plates around the ink supply path opening, This in turn makes it possible for ink to bleed between the plates as it travels along the ink supply path
Ink that leaks out of the supply path and reaches between this heater and the adjacent tank plate can adversely affect printhead life

Embodiment Construction
[0018] For a general understanding of the embodiments, reference is made to the accompanying drawings. Like reference numerals are used to designate like elements throughout the drawings.
[0019] As used herein, the term "imaging device" generally refers to a device used to apply an image to a print medium. "Print Media" is a physical sheet of paper, plastic, or other suitable physical medium or substrate for an image. The developing device may include various other components such as a correction machine, a paper feeder, etc., and may be implemented as a copier, printer, or multifunction machine. A "print job" or "document" is generally a group of related pages, usually one or more collated copies of a set of original print job pages or electronic document page images from a particular user, or otherwise related . Images generally include information in electronic form, which can be rendered on the printed medium by a markup engine, and can also include text, diagrams, pi...

A heater (110) for use in a phase change ink printhead reservoir is provided that includes a first insulating layer (168) having at least one ink supply path opening (271...274), and a second insulating layer (178) having at least one ink supply path opening that aligns with the at least one ink supply path opening in the first insulating layer. The heater includes a resistance heating trace arranged in a serpentine pattern between the first and the second insulating layers. The resistance heating trace is configured to receive electric current and to convert the electric current to heat. The resistance heating trace includes a trace ring for each ink supply path opening in the first and second insulating layers that forms a continuous perimeter around the corresponding ink supply path opening.
Description
technical field [0001] This disclosure relates generally to phase change inkjet imaging devices and, in particular, to apparatus and methods for heating print heads for such imaging devices. Background technique [0002] Solid ink or phase change ink printers traditionally receive ink in solid form, either as pellets or ink sticks. A solid ink pellet or ink stick is typically inserted through an insertion port in an ink loader for the printer, and an input mechanism and / or gravity is used to push or slide the ink stick along the input channel towards the solid ink melt assembly. The melting assembly melts solid ink into a liquid, which is delivered to a molten ink container. The molten ink reservoir is configured to hold a quantity of molten ink and to communicate the molten ink to one or more printhead tanks, optionally located adjacent at least one printhead of the printer. [0003] The printhead tank may be formed from a plurality of plates or panels that are glued or b...
