Restoration Project #46 - Brother M-1109
Earlier this year I was looking for a simple parallel port printer to use in another project. I scouted e-bay for cheap options and came across this one. A 9-pin dot matrix printer. It seems to be complete, but the "untested" note in the listing was hinting towards some issues. I found out that the printer head connection - a flatflex PCB again - is busted and doesn't provide continuity on most of the lines, including the ground one, so not a single pin worked (I did test the connector off camera) I managed to brindge the broken part, but since it's now slightly wonky in the moving path, I have no clue how long that fix will last. Maybe this is a good chance to try out a PCB prototyping service that offers flexiple prints? I'm considering the option, keep your eyes peeled for a possible follow up!
...oh, and of course I'm also working on the other project, so the printer might make an appearence in yet another video too!
