I have a brother hl 5250dn. recently after printing about 100 pages, it started having a clicking sound and stopped printing. anyone knows why?

Brother is totally fucked up under Leopard, found so far no chance to fix it.  Brother's own printer drivers are 10.4 only -- lame

SOURCE: toner light after 1K pages

On my unit, the toner light was lit steady amber and the Status light was steady red. I tore a small square out of a post it note, off the top (so that it had adhesive on it), and used that to cover the sensor path way found on either side of the toner cartridge. It is a clear plastic hole, centered toward the bottom of either side of the cartridge.

SOURCE: My Brother HL 5250DN jams frequently when I try

Paper dust/particles tend to accumulate on rubber rollers and they lose their grip (friction) of the paper.
Try to open every door and wherever any rubber rollers are visible, larger or smaller, clean them with isopropyl alcohol or some other oil-free and residue-free cleaner. Do it with the printer switched off the mains power, this should allow you to rotate the rollers to clean them all around.
Should help.

Clear the jammed paper as follows.
Observe Cautions signs in printer.
Always remove all paper from the paper tray and straighten the stack when you add new paper. This helps prevent multiple sheets of paper from feeding through the printer at one time and prevents paper jams.
1. Press the cover release button and then open the front cover.
2. Slowly take out the drum unit and toner cartridge assembly. The jammed paper will be pulled out with the drum unit and toner cartridge assembly.
3. Pull the paper tray completely out of the printer.
4. Close the front cover.
5. Pull the jammed paper up and out of the printer.
6. Open the front cover again.
7. Open the back cover.
8. Pull the tabs at the left and right hand sides toward you to open the fuser cover (1).
9. Using both hands, gently pull the jammed paper out of the fuser unit.
10. Close the back cover.
11. Pull the duplex tray completely out of the printer.
12. Pull the the jammed paper out of the printer or the duplex tray. Put the duplex tray back in the printer.
13. Push down the blue lock lever and take the toner cartridge out of the drum unit. Clear the jammed paper if there is any inside the drum unit.
14. Put the toner cartridge back into the drum unit until you hear it lock into place. If you put the cartridge in properly, the blue lock lever will lift automatically.
15. Put the drum unit and toner cartridge assembly back in the printer.
16. Put the paper tray firmly back in the printer.
17. Close the front cover.
18. Make sure that the Paper LED is now off and the printer is ready.
After clearing paper jam if noise persist printer may need a Repair Tech and parts replacement for broken or wore parts.

When the toner light is on this means the toner is empty and needs to be replaced before it can print again. Replace the toner and you will be able to print again.
