Our printer is an HP Laser but not sure of the kind , ANYWAY when it starts to print , it will make a horrible clicking sound . What could this be, and how can it be fixed ? We have this printer in a public libary and its getting used daily nonstop , it also will get jams currently .

thanks If I knew your model etc Laserjet 4MV etc, i'd be able to help you better. Not all laserjets are the same to just pin POINT a sound to a specific location. Its most common that a clicking sound is gear teeth jumping or sloppy. If this printer is worth fixing, I would have a maintenance kit performed on it. Most of the time if you are unable to perform this TASK yourself its cheaper to just get a new printer as for a computer shop could CHARGE you close to $200 to fix this if they have labor rates like the ones in my area which are $90 an hour + Parts.HP, Lexmark and other companies produce very low qaulity printers and a very affordable price. This may not be your case, but dealing with REALLY cheap printers in the past has proven to me that they may last up to 2 years or more if your really lucky, and then needs to be thrown away and replaced. This has been my experience. If the printer was one of those hot off the shelf $30.00 deals, it may be time for a new one.
