Interference on conductive sensor

[Job_van_gennip 23]

Hi guys,

 

I do not expect anyone to run into this problem, but wanted to share it anyway. Today I was repairing a printer of one of our customers, they build lettering for advertising. Their conductive sensor did not work anymore. After having ruled out everything and even having installed a new sensor I dissassembled the printing head looking for anything in the head responsible for the interference. Also this yielded no result, I was out of ideas, but just when I was about to give up and take the printer back for even more elaborate research I noticed a neon light behind the printer. What turned out the high frequency transformator that powers this neon lighting caused for interference. We turned of the lighting and all of a sudden everything worked perfectly again. So don't put neon lighting next to your printer😋.I do not expect it to help anyone since it is so specific, but I wanted to share it anyway.

 

Kind regards,
