I finally pulled this thing out of storage to hook up. Plug it in and power it on, and I don't just get the initialization tone (beep), I get a loud persistent tone. There's no jams, the head carriage moves smoothly as well as the platen wheel. Suggestions?

Thanks,
D

Check the "paper out" detection switch. It might be bent or otherwise damaged. You did put paper in it? If you don't want it to honk at you when it runs out of paper, there should be a DIP switch inside on the main board you can flip to change that.

The power-up behavior of my functional IBM 5152 unit is at [here (http://minuszerodegrees.net/5152/misc/5152_power_up.htm)].
With paper, there is no "initialization tone (beep)".
Without paper, there are 8 beeps.

It does none of those things; here is a video of what it is doing...

If my 5152 had that symptom, I would try (in the order shown):

1. Try powering up unit after the ribbon cartridge has been removed. (I.e. rule out jammed cartridge.)
2. Open unit and have a thorough inspection.
3. Re-seat cables and chips.
4. Check DC voltages (referring to manual).
5. If above not fruitful, try fitting a new ROM. (ROM image at [here (http://minuszerodegrees.net/rom/rom.htm)], noting that it is not a 27xxx.)

I had the same exact issue with my IBM5152 graphics printer. To solve the issue, all I needed was reload the paper. Before doing the reload, that incessant beep drove me absolutely bonkers! It was my wife's suggestion to reload the paper. I guess we all know who is the smart one. LOLZ!!!

After seeing the video this doesn't look like a paper out problem. Usually the printer will initialize first, move the head and do it's thing before it senses there is no paper. Then it will beep with a light lit solid. This printer does not look like it is initializing at all so I would suspect something in the hardware or a jam of the motor or initialization routine. As suggested it could be a ROM and I would for sure take it apart and check all the ICs are seated properly.
