Markem Imaje Laser Printer Print Head Coder 9840 model#- ME3509-204E We got this with a bunch of other Markem Stuff that came from working a working Factory. This is used, but working condition -100% assurance this will work perfect. I think the factory used different printers. They took these off, tested them and they sat on shelf for 3-4 years. I have 4 of these heads. These two are in similar condition. They are good and working, but they show more sings of use than the other two I am selling. ****Please look at my other ME3509-204E's I have some some in various conditions. All will work as they should. I will give discounts if you want multiple units. ****** FREE USA SHIP / Will ship international / Will ship overnight, if I am able, please inquire as to my availability. please ask questions. Please look at pictures.
