Early on this fine Saturday morning, I went to print a few pages of info on connectors for a project....
The first page printed fine.
The second one was halfway out of the printer when the printer abruptly stopped and turned on an error light.
Normally, that light blinks for quite a while before things get really bad. And the print quality gradually deteriorates. It doesn't just shut down in the middle of a page!
So I jiggle things, and cycle power, and... as the printer runs through its startup process, it stops with a klunk and turns the light back on.
So I guess the drum unit is jammed.
Have to chase the cats out of here (later), put down paper or something, pull the drum, and see if it's something I can unwedge.
And then, presumably, it'll be Amazon Prime to the rescue. Because even if I could find a replacement drum locally, it'd likely cost almost twice as much as ordering from Amazon. That's the trouble with living in the hinterlands the middle of Silicon Valley.
Update: Braving the cramped space under my desk (muscles in lower back and groinal region still being troublesome), I pulled the drum & toner stack out, unstacked them, rotated the drum manually, blew dust off the corona wire (and wiggled the corona-wire cleaner back & forth), removed sundry detritus from the drum with a Kleenex® brand kleenex, reassembled it, re-inserted in printer, turned power on, held my breath, and... no frowny light! Seems to work OK now.
Say, you don't think the sudden error was the result of cat dander on the corona wire shorting out the HV, do you...?
Looking in my office closet, I find various used toner cartridges that I'm not really going to refill, some of which are for the previous printer of blessed memory, for which I also have a couple of used-up drum units. Well, off to e-waste with 'em. Had I found a used-up but not totally-defunct drum unit for this model, I might have used it temporarily while ordering a replacement, had the take-it-out-and-clean-it action failed.
