I've got an HP Laser Printer from about 15 years or so. About once a year, the printer stops responding and I have to remove the board, put it in the oven for 10 minutes or so to revive it.
- Paul-Craft 3y agoWhat even is the theory on how that could possibly work? I believe you, it's just that I don't have any mental model of how baking a circuit board makes it work right for a year, and how it keeps working to fix the issue.
- brabarossa 3y agoThe theory is that 'baking" it could reflow a bad solder joint and fix it. A popular fix of last resort.
- Paul-Craft 3y agoI get that that could work and might solve the problem entirely. What I don't get is why you'd ever have to do that every few months.
- mrguyorama 3y agoLaser printers have parts that can get very hot. If their "baking" reflowed the parts, but just barely, maybe those hot parts would just cause the exact same problem all over again.
- Paul-Craft 3y agoAh! There we go! That was what I was missing. Thanks. It all makes sense now.
