Hp HP Color Copier 120

HP 4300 closing top cover, 220 VAC into 120 prntr

So help me, it won't close. What's the secret, please? I don't want to force it, but it just refuses to drop down.

Also, if a 4300 rated for 120VAC is plugged into 220 volts -- happens all the time over here in Baghdad -- what are the parts that commonly need to be replaced?

(If anyone wants to know what parts need replacing on the 4600, boy, am I the expert.)
OK, I got the cover closed. (Pushed down harder.)

Now then, what parts typically need replacing when a 120 volt 4300 is plugged into 220?

I would think the power supply and fuser are two items which will need to be replaced. It is really difficult to be sure without having one in front of me. The only suggestion I can make is if you have a working 110V unit would be to use that as a parts unit for the repair of the non-working unit until you find out exactly what parts you will need. Power supply is a pain to replace as lots has to come off, but that is what I would start with. I doubt you will do any more damage if you replace the ps even if the fuser or something else needs replacement. If you need the service manual, click on the link by my name and I will use yousendit.com to get it to you. Retired Military myself and hope you get to come back to the land of the big PX real soon.

What about an external transformer to step the input voltage down to 120?

I do not think he is asking how to run the printer, but how to fix it after it has been plugged into the wrong source. I am sure our military has plenty of 110V power sources, just people keep plugging 110V items into 220V sources.

I don't think the fuser would get zapped since it only gets powered up at print. You could most likely get away with just replacing the power supply RM1-0107-000 New ones go for about $275. Cheaper than a mil spec toilet seat.

Good idea by dmzcompute to swap parts with a working 4300, but I don't have a working one. Will see if the command wants to chance $275.

Ref the observation about both the Fuser and the Pwr Supply going out, that's usually what happens with the 4600. The LVPS has two fuses, but they usually fail to catch the surge of voltage in time. The Fuser has no fuse, and it always, reliably gets blown up.

Therefore, am thinking the Fuser will have failed here, too. Leaving this post, will check on the cost. Thanks for part number, moe. And thanks, dmzcompute, I've got a manual (bought on ebay).
