Let me guess: your mfc is about 2.5 years old.
Had a lot of mfc which wont power on because of a bad capacitor.
Thanks to saving policies of brother! Cheap materials which wont last more than 3 years.
This cant be fixed. What you can try is to buy a 2nd hand mfc 5440cn or a 5840cn with a bad printhead and change the main pcb.

My printer is not printing

Without knowing any more, all I can do is take you through a tedious set of steps:
  1. Is it plugged in? Unplug the power cord at both ends, then plug it back in.
  2. Is it connected to your computer? Unplug the cord at both ends, then plug it back in.
  3. Is it turned on? Press the power button. Do any lights change (go on or off, change color, flash, etc.)?
  4. Send a print job to the printer. Does the printer show any signs of realizing it's been asked to print something (an indicator light or something moving inside)?
  5. Open the print queue. Delete all the jobs that are in there. Shut down the printer. Restart the computer. Turn the printer back on. Try printing.
  6. Are you getting error messages?
  7. What happened before it stopped working? Did you install new software? Move anything?

MY HP printer can print but does not copy

Same thing just happened to my fairly new 7520 Hp.

I shut my machine first with the shut off button and then unplugged
it for about 5 minutes. Sounds like you tried this and I believe this did not work for me either so I just went into the HP official site and downloaded my printer again. Downloading your printer from their
site is easy and quick instead using the cd. It automatically removed my old printer and installed the printer again. The problem has not returned.

Another problem I just had and because I think one of my new
cartridges (yellow) is somehow damaged. I got a black line down
my pages with a note that my yellow ink is missing. Had black line only when printing and not copying. I reinserted the yellow ink and took a light damp qtip and slightly wiped the machine screen on each ink cartridge.(this screen meets the new opening from each
new cartridge. The black line left.

Hope this helps.

HP LaserJet 4100 for all applications in windows 7. When I go to print a document and click on print. The print screen exits, the print job doesn't processes, and the print queue stays empty. Noth

Ideas? Yes. I had this happen on an LJ 1000 while trying to print my tax return. I tried emptying the queue, removing power from the printer, etc, etc. What finally worked was to empty the queue (again), disconnect power from the printer, shut down the computer, plug in the printer again, restart the computer, queue up a print job again, and hit PRINT.
Hope this works for you

Hp officejet 9120 won't power down but won't print either, it seems to be locked up, display just shows dots scrolling right to left

Unplug your printer from the outlet for several minutes and repower it back up. I have had this with my printer and usually solves the problem.

Your question is kind of confusing. From what I get is that your printer is saying to not shut it down by unplugging it or breaker switch? If that's the case simply hold the power button till it shuts down (if it doesn't shut off after 5 seconds release and it should shut down).

If the message is saying do not shut it down at all, try and wait it out. It could be loading drivers or saving data etc etc.

Another problem it that you could have print jobs waiting and shutting down could corrupt data. Try and look at the bottom right of your computer screen and find a printer icon. From there you should be able to right click and disable pending print jobs etc etc.

Hope This helps!

I have had the mp480 for a few months and absolutely love it! The problem is that all of a sudden it shut itself down!!!! this never happened before, i had printed out a few things prior to this happening,...

This could be a problem with the power adapter of the printer. get an expert to check out the power adpter if it was connected to an unprotected power source.
