Trash rack victory!! Half price monitor and memory of a free one

Someone threw out an HP Z27 monitor for the understandable defect of something having struck the upper left of the screen and ruining it there. I bought for about half the cost of the original monitour a replacement LCD direct from China for the thing, which arrived to at work. After doing some real botchwork with a sewing machine on a skirt I sortof succeeded in altering, I reassembled the monitor and it works now. 3840 × 2160 and I have to run it at 25/100 brightness (via OSD) to be able to look at the thing.

Fixed an HP LaserJet from 1998

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.
