Dear electronics people,
Hope you won't be annoyed by this post. I'm completely ignorant in electronics (but also curious and motivated to learn). This post only marginally fits here, perhaps, so apologies upfront.
In short: how can it be that I opened my inkjet printer to see if something is jammed inside, and after I reassembled it it wouldn't power on, and when I in frustration bought the same day another printer, almost identical model, and had to open that one too, it too wouldn't power on afterwards?
Mind you, I'm not asking you guys to fix my printer or something like that. I'm interested in the pure electronic science of this predicament. Also, perhaps there's something important I need to notice while opening my next printer...
Both printers (Canon PIXMA) were second hand, several years old. No power problems before opening. No blows or abuse during opening. No indication of any burnt fuses, no sparks or anything. Tried giving them a rest, pluging with other cords, all around the house: nothing.
I suppose the culprit in such cases is the power supply. Can't tell you anything about mine, I don't have a multimeter.
So: does this make any sort of electronic sense? Surely Canon doesn't install a self-destruct mechanism in their printers to ward off hobby technicians. I assure you I didn't touch any component other than the paper-feed rollers.
What do you think?
