HP Laserjet 1200

Hi Guys,

I'm new to this, so please go easy on me!

Our client has an old HP Laserjet 1200. They've reported that it's currently making loud sqeaking noises (and other loud mechanical noises which weren't there before) when they print. They mentioned that it still prints fine, but are concerned with it.

The printer sits in an office just off a warehouse and therefore gets completely covered in dust.

Before we write this printer off, I'd like to know if there are easy ways of maybe cleaning this printer? I'd like to be able to take the printer apart and clean the insides maybe, and hopefully put the printer back together afterwards!

Can anyone offer me any advice on performing a service on this machine? Is there anything I need to look out for?

Please bear in mind that my printer knowledge doesn't really stretch beyond changing fuser units etc.

If anyone could provide me with information that helps prevent me looking like a complete lemon when I look at the printer, I'd be most grateful!


There is not much to this printer. The squeak is possibly from the toner cartridge. The only cleaning is to remove the toner & paper tray --- it snaps up then out at you, & using a can of compressed air blow out the insides. Don't just do a puff puff puff as I have seen timid people do. Hold down on the air trigger & point the straw inside the printer from one side to the other. Also, blow off the edges of the toner cart.; toner build up there can cause squeaking. You can lift the printer in the air upside down with the toner door open & shake the printer a bit. Some debris may fall out. I have seen before that a piece of black plastic has come off a previous toner cart. & Lodged in the paper path & caused squeaking. When it fell out during the upside-down shaking I realized I never would have seen it. Also you should clean off the gray paper pick up roller you see in the middle of the printer where the toner goes. It is oval shaped & the side you see is the side to clean with a rag moistened with rubber restorer or rubbing alcohol or even water --- just rub on it side to side.

Hi Dave,

Thanks for your advice.

I shall give this a go when I'm next at my client's site, and will let you know how I get on!
