Question about HP LaserJet 2100 Printer
My HP LaserJet 2100 printer has started squeaking while it is printing.
What could be wrong and is there anything I can do about the problem?
I would try another toner cartridge. There is a drum inside of cartridge itself that turns also when you print.

Typical cause is the toner cartridge (particular if it is a remanufactured cartridge). Toner can sometimes fuse to the parts, causing them to rub and bind.
Another common cause on those units, though, is the mirror motor on the laser scanner assembly. This issue may manifest as a high-pitched squeal, rather than a steady chirping (if that description makes any sense), and it will only occur while the printer is actually printing. If you get the squeaking during startup (when only the transport mechanism is running to ensure the all the gears and rollers turn properly), then the issue is probably not with the scanner motor.
Now, anything inside the scanner assembly is generally not considered to be a serviceable part. The only officially supported remedy is the replacement of the whole scanner assembly by a qualified service technician. However, since the 2100 is only a small-workgroup-class printer, replacing the laser assembly would cost you about as much in parts and labor as it would to get a newer-model refurbed printer.
But the 2100 is a real workhorse--designed to last. If you can alleviate this one problem, the printer may serve you another 5 years or more. [Then again, this question is almost 5 years old already.]
The following video (it's not mine--I just came across it in a search earlier today) shows how you might be able to resolve the problem yourself by lubricating the mirror motor, rather than replacing the scanner.
The operation might not be for the faint of heart, but the video is pretty detailed, especially for guiding you through disassembling the printer. You'll find that the housing of your 2100 is completely identical to that of the 2200 seen in the video. Removing the covers to get to the guts will be exactly the same, but the internals are somewhat different, due mostly to the 2200 having been redesigned to allow for the inclusion of a builtin duplexing unit on some models (such as the one in the video). The 2200 also employs a different scanner. I have removed scanners on both, but have never tried to take one apart on either, so I cannot say how they might compare.
