My Hp 1200 laser printer makes a high pitched squealing noise and I have to pull the plug out to stop it.

Hi Narendra,
This is really difficult to answer without being on site!
All I can think of is perhaps you have some piece of paper stuck inside.
If you had some paper stuck before, and you had to pull it out causing a piece to rip off try putting the bits back together again on the desk, if you can't find them all then that's the bit still stuck inside you need to look out for inside.
If in doubt you will need to get your local engineer to have a look inside.
Good Luck.

Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.

Try replacing the Drum Unit, this is a problem I have encountered many times as a service technician. most recently I had one that was at 89% remaining and every time the unit begins the print process it makes a high pitched squeal.

The surge protector or UPS may not be allowing sufficient voltage through to the printer. HP printers do not have built in speakers of any kind. Because of this, they are not capable of making any beeping or squealing sounds. If any noises such as these are heard then the printer is probably connected to an Uninterruptible Power Supply (UPS) or a backup battery. To verify that the UPS is the source of the noise, plug the printer directly into a wall outlet bypassing the UPS.

The following are common symptoms:

• High pitched squealing, beeping sounds, or alarms (UPS)
  NOTE: Noise over the phone line can also cause high-pitched squeals and beeping sounds.
• Inexplicable or false error messages
• Printer will not "wake up" from sleep mode
• Printer appears to be DOA
• Incorrect printout
• Slower than normal printing
• The printer control panel display is blank or shows garbled characters
• Accessories, such as attached copier/scanners, do not function properly
• Monitor loses power or shuts off
• Computer reboots when job is printing
• Job only prints half way, causing a paper jam

If it is necessary for the product to be connected to the above-mentioned devices, consider the following items:

• There are many UPS configurations and load conditions that can affect proper printer operation. Depending on these configurations or load conditions, printer functionality cannot be predicted.
• No damage to current HP LaserJet products will occur, but, depending on their particular UPS configuration, the printer may or may not operate properly.
• Printing while on a UPS battery backup is not recommended because of the large power requirements of HP LaserJet products.
• If the HP LaserJet printer is not operating properly and power line conditions are suspected, try a different circuit (a different wall plug located away from the current one), or try removing it from the UPS.

The Laser Scanners go out in the 2200/2300. Based on the noise you describe, high pitched screech, the laser scanner needs replacing. However, if you push the large go button, you will get a secondary light code that will tell you specifically the problem and then go google the secondary error light pattern for 2200's.. Good luck

If it's a high pitched squeal it means the bearings in the laser assembly are worn out, the laser assembly in this model can be very expensive, just a guess since I can't hear the noise in person.

It proberly has dust in the printer near the spool (the picture below)

noise is caused by the toner cartridge and paper is not going trough because there is a plastic milar clse to the feed roller that is bent,find it and push it towards the inside of printer (is a black or dark brown plastic mylar)

Possible noisy laser unit or fan. Most likely the laser unit.

However,

You can pull the fuser out by pulling the rear door ALL THE WAY DOWN and remove 2 large screws and pull the rear cover off, then the the left and right small covers, the plastic guide on the bottom and 2 fuser screws. Be careful with the small wires on the right side.

You have to remove all covers to get to fan and laser which is a triangular shaped black box under the top cover.

If the printer works fine for you, but doesn't work properly for someone else I would assume user error. Just make sure that there is plenty of paper in the tray and that it is centered. Also look around for any small peices of paper that might've gotten stuck near the tray, preventing new sheets from getting pulled.
