HP 5000 noise (fan?)

My HP 5000 is working fine, but has developed what sounds like a noisy fan. It's a fairly constant noise -- sort of a whiny hum. Sometimes it gets louder or softer. It's extremely annoying, plus it makes me worry that the printer's sick.

It doesn't make any other noises when printing, I don't get any paper jams or feed problems. Print quality is good.

I did pull out the toner cartridge to see if it made any difference (it didn't).

What might be causing the noise? Could it actually be a fan problem? Is it something that an amateur could clean or replace?

Thanks in advance,

Anyone got any suggestions for me? My husband took the printer apart over the weekend and tried to clean the fan. It's still noisy, but we think the noise IS coming from the fan (not sure, though).

I searched the HP site and I can buy a replacement fan from them for about $40 (including shipping). Does that sound like a good first step, or is there an easy way to see if the fan is really the issue?

FWIW, I checked the number of pages printed, and it's about 42,000. That doesn't seem excessive to me (especially since I bought the printer in December 1998, IIRC).

I know laser printers have come down a lot in price since I bought this one (I paid over $1,800 including an extra paper tray and more RAM), but I'd rather not replace it, if it can be fixed at reasonable cost.

TIA,

Sounds like the Laser/Scanner was the sound coming from.
You can fix it by a small drops of light machine oil.

Take the top cover off there is a black box(Laser/Scanner) under the cover.
Take a look of here you will know what to do.

Oiling the laser scanner is risky, and any noise it makes won't be constant as in only runs when printing.

You can confirm that the fan is the problem, by inserting something such as a wooden skewer into the blades to stop it turning, and then switching the printer on. If the noise doesn't occur, remove the skewer and see if it then starts as the fan gets up to speed.

You won't damage anything if you only stop the fan for a few seconds.

If it is the fan then just peel back the label on the fan and put a small drop of synthetic oil on the shaft and press the label back on and see if that quiets it down.

Weird ... I could have sworn I posted a message last night, but I'm not seeing it.

Anyway, we didn't think to try stopping the fan to see if the noise stopped (which was a great suggestion), so I went ahead and ordered a new fan from HP yesterday afternoon.

My husband was reluctant to try oiling anything in the printer (he's not real mechanically minded) and I feared that an oil spill inside the printer could make the situation worse.

When the new fan arrives (next week)and he opens up the printer again, I'll see if stopping the old fan stops the noise. We'll probably throw in the new fan, regardless. I don't think I'd be able to return it anyway.

Oiling the fan would only be a temporary fix anyway, even if it did quiet it down. Both ball bearing and sleeve fans are lubricated with thick mineral oil bearing grease at the factory (ie, Molykote G-series greases), mixing a synthetic oil with a mineral grease isn't really a good idea.
