So there was a printer I said I would fix that, besides being old and sitting on a shelf for maybe 5 or 10 years, would print but jam alot. First the old toner cartridge from 10+ years ago that was left in it all this time was replaced, then the duplexer stabilized, but after some time attempted use, it ended up jamming every sheet and was so annoying.
Disassembling it showed that the inside of the fuser roller (the one that actually heats up and burns the toner onto the paper) had a mess of burned toner. Cleaned that up and reassembled the toner. Still would always fold over the top left corner of the paper and jam just as it got to the fuser. Looking along the paper path where this fold would have been made, I noticed a blunt projection – that had been manufactured there – that might be doing it.
HP does not usually misdesign their printers, so I slept on it for about 2 nights and 1 day. Deciding I couldn’t make it less useful for them, I used a makeshift file to wear it down. I cleaned the area up and reassembled it and it has not jammed once for me after printing ~80 sheets from all the different paper sources. I give it back tomorrow in what I think is fully functioning shape.
By education, I am an engineer. In the professional of chemical engineering, specifically petrochemical or petroleum engineering, unit operations called “catalytic crackers” exist. These “crack” larger molecules into smaller ones. As an example, octane (nC8) can be crackt into propane (nC4) if desired.
All occupations have their own language, whether cryptolect or just technolect. In mine, these are termed “crackers” (definition 5), with sometimes unfortunate effects.
I first lived in a house built in ~1900. Then my parents moved to a place much newer (8os), but I still visited my grand parents’ places, which were a Sears Roebuck house and a DIY from the forties. Both had really iffy old electrical wiring (you can probably guess what the title means now) that more often than not did not have grounding.
Both of them had recourse to “cheater plugs”, that allowed you to plug a 3 prong (grounded) plug into a 2 prong (ungrounded) outlet and had a little tab or wire that you would then screw to the faceplate of the outlet or connect to a ground. Riiiight… I don’t think I’ve ever seen that done.
An aside: a school I went to for two years had 3 main buildings, 1 built in the 50s or 60s, and the other two in the 1860s maybe. In a class room that was way too small, like many of them, there was the only power outlet on the wall, about 6 feet up, in the middle of the wall. Why? That’s (most likely) where the gas jet was at first. When it was replaced by wires, they used the existing conduit. I don’t remember where the light switch was, or if that room had cieling lights or not. Anyway the outlet was ungrounded, and I think unpolarized, with a cheater plug supporting (literally!) the power strip hanging down about 4 feet, which an old IBM PS/2 486 was plugged into on the teacher’s desk, or next to it.
This day, though, I used one that I had to provide a path to ground for a UPS that powers my medical equipment and an old Clock of great value. The thing had its “wiring fault detected” LED lit ever since I moved to this apartment, and now it has a ground through the radiator pipe in my bedroom. Improvement!
I’ve mentioned at least once here that I have an MSI WindPad 110W tablet. Someone made one of those “don’t read the comments” comments I read insulting the company for its name (they called it “FartPad”) and model (110W = 110 watts, an outrageous power draw for a tablet). For their understandable reasoning, but not unjust trollishness, I agree it is odd sounding.
None of that has to do with my improvement to it, which is to remove the cameras.
This has been sitting in my place, and then scanned to a PDF, but I have to post it here before it gets lost in a fire or I die or something: POWRfull
It is a slide rule for metricating, or going backwards too. Far more than anything else for the purpose, it is a classical “New Jersey style” tool that does one thing, well. Here are immages:
Other than being made by Sterling in the United States, and of course being in the ISRM about two-thirds of the way down this page, it is perfect. It will live again, especially when I find out how to vectorize it or make Excel use it.
I have had, for some time, an “Irulu W10” tablet. After “refreshing” Windows 10 on it, then reinstalling Firefox, then generating a new profile for Firefox, then reinstalling Firefox, I now want to do a completely fresh reinstall of Windows 10. This is more of a trip than the MSI WindPad I had been using previously.
My immediate boss/supervisor lives on some nasty town road that is ill maintained (he says, I’ve never been there) and has even worse utility service. He can’t get anything but dialup or satellite and even the infamously reliable Bell System copper wire doesn’t last long in a power failure because the booster in the box halfway into town doesn’t have a long lasting battery.
I have been using the best YouTube video I know of for sound testing when I plug in my speaker-monitors: cz3DEStqO-U – entituled, “Dale annoying Squirrely the broody hen“. I do not know the breeds, but the white broody “Squirrely” has the most interesting complaint voice.
I had a broody hen, I don’t remember her breed, who would make this sound that had a glottal stop in it. I think that is what you would call it. Anyway, this hen’s vocalization is very worthy of record.
Bonus: listen closely during the intermission when “Dale” stares at the lens. You can hear someone in the distance: “What are you doing in there?”
