Our printer is making a really loud, sort of grinding noise and then it jams. why is it doing this? When we start to use the printer in the morning it also makes the grinding noise when it's warming up.

You need to check a number of areas, but first try to determine where the noise is coming from...

1) First, where is it jamming...If under the cartridge, the cartridge drum may be too tight. If you have another or an old one (even if empty) try switching it out.
2) If the sound is coming from the front, your manual feed rollers (front) or main paper tray pickup rollers or gears (below) may be slipping.
3) If the sound is coming from the rear, check the fuser gears. It will have a main, big gear that meshes with the big drive gear (swing gear) inside the printer. The fuser is the accessed by removing the rear cover. The fuser can be very hot, as its job is to fuse the toner to the paper just before it exits into the bin. Let it cool off, then remove, inspect the gears for wear, re-seat it and test print--listening again to see if the sound is still there or gone.
4) If the sound is coming from the top rollers where the paper exits, check the gears that drive these rollers for wear and/or skipping teeth.

One of these will be the culprit. The hardest part is isolating the source of the sound.

Grinding noise when I turn it on

Ive solved the problem, I took the side panels off, and found a piece of paper jammed in the gears, not sure how it go into the place where it was.

If anyone gets this problem, use the Epson disassembly guide found at:

My laserjet 4 has a gear grinding sound during the warmup process. when i try to print, the paper jams under the toner cartridge and is smeared in places when I pull it out.

The drive gear probably has a tooth or a few teeth missing. While someone who is technology savvy can figure out how to replace it it would be best to take it to a repair shop. The gears for it are hard to find at times for the III and 4.

Canon PIXMA 530 grinds away

I had a persistant grinding noise about 30 seconds after the printer finished printing. It's been going on about 2 months. I did one thing which seemed to work. So try opening the cover on the back of the machine by lifting upward on the gray lever in the middle of the back of the machine. Leave this cover open during and after printing. The grinding noise went away.

Makes loud sounds

I had the same problem with the loud grinding sound. The gears on the cartridge(s) is not turning but rather stripping creating a grinding sound. Reinstall all of the toner cartridges. If that doesn't work, pull each cartridge out and manually turn the gear on the cartridge. If the problem persists, you may need to purchase a new toner cartridge.

Loud clattering noise

-Open the Front Cover. -Remove the Toner Cartridge -Remove the Drum Cartridge -Next locate the black gear attached to the end of the Drum and turn it with your fingers. -Check to see if the gear is locked, or difficult to turn. The gear will only turn in one direction. -If the gear won't turn at all, or if it catches while you are turning it, or if you hear the same noise when you turn the gear that you heard when the machine was on, the Drum Cartridge is the cause and will need to be replaced.
