Hp HP DeskJet Plus

HP Laserjet 4 Plus beeps during printout

I have an HP Laserjet 4 Plus that was jamming just after the fuser. I cleaned the paper path, pulled the fuser to inspect for dirt or damage, then reassembled the unit. It now prints, but it emits a long beep during the printout of the test page.

Can anyone tell me what could cause this, or how to fix it?

Thanks.
Since there aren't any audio devices in the printer, I'd suspect the most likely cause would be the toner cartridge. http://www.fixyourownprinter.com/specials/toner/hp/S206

I forgot to say that I did already try a different toner cartridge.

When does the beep start? Does it start before the paper is fed, during the feed, or when the paper hits the exit rollers?

It beeps when I first turn on the printer. It beeps when I print during the feed.

Sounds like you are plugged into a UPS box.

Plug the printer directly in the wall outlet.

Could it have anything to do with the fuser? The toner seems to be fused though. But it seems to beep when warming up.

Never, ever heard a fuser make any sound in that model. I have heard one or 2 make noise out of the gear train on the left side. Out of the hundreds, if not thousands of that series that I've worked on, the only noise I've ever hear came from either the toner cartridge or the gear train on the left side. To quiet the gear train, I just take off the left side cover and squirt lubricant in the holes in the metal gear enclosure. That's always worked for me.
