mtbc: maze I (white-red)
Both laser printers survived the move. There are now two because I needed a printer before the colour printer arrived from Tennessee. Happily, both were fixed by removing and checking over the parts that users typically expect to change occasionally anyway.

The monochrome printer was printing a vertical line on each page. Removing a fibre of some kind from its innards cured that. Then, a repeating pattern appeared on pages, like a fibre in a different place, but another review of its innards cured that somehow.

The colour printer was not printing colour at all, only black. I suspected CUPS but the problem persisted when netcat'ing PDFs directly to port 9100. Reseating the toner cartridges in the drum unit cured that, the hardest part was noticing the release button for the printer's front cover.

Of course, I gave the corona wire tab some slides back and forth while I was in there, as one does.

Now I have self-adhesive labels with our new address on them, with the help of lp -o media=Manual labels-L7551.ps.
