Why is your printer so loud?

Answer 1

My printer doesn't make a clicking noise; it does make a sound like the Orange Blossom Special while warming up, though (seriously, you'd think a train was coming through).

If it's an inkjet, it's probably the toothed band that moves the print head from side to side slipping over the notches as the print head self-registers, which it usually does by moving as far as it can to one side. The printer ensures this by moving the band far enough to get the print head from any position to the side, which causes it to make that characteristic clicking noise before starting to print.

Answer 2

The reason your printer is so loud is because of how it is made. Some printers are made to run quietly while others are not. Typically, more expensive printers will make less noise than cheaper models.
