You might have a bad power supply.

Look for a green light on the plug that goes into the machine. Also look at the black box on the power cord, is it warm?

Corona wires need to be replaced, or developer rollers are worn. Wires are the cheapest to replace, but it most likely the developer. You'll need a developer kit and service manual to replace. Your best bet is to contact an authorized service dealer.

How do I replace the brother fuser?

    The fusing unit and the parts around it are hot! Be sure to wait until the fusing unit has cooled down sufficiently before replacing the fusing unit. If you touch the hot parts, you might get injured.
  1. Turn off the machine's power switch. To avoid injury, wait until the machine has cooled down sufficiently before you replace the fusing unit.

  2. Open the back cover (1) and the scanner unit (2) of the machine.

  4. To release the fusing unit from the machine, release the lock levers that are on both sides of the fusing unit.

  6. Hold the handles on both sides as you take the fusing unit out of the machine.

  21. Caution
      Please be careful when replacing the fusing unit. Do not put pressure on the fusing unit; it should go in easily. If it does not, make sure the fusing unit connector is free to move.
      Do not apply force! It could damage both the fusing unit and the machine.

We had a power outage and are having trouble faxing to China....It rings, seems to connect then gives no error code and puts the fax out for re-dial...Any suggestions on how to fix this?

Plug a phone into this outlet and see if you get a dial tone. If you do not you will have to call the phone company. If you can use a phone at that outlet but not your fax, then you know that the power surge that came when the power turned back on damaged a fuse in your machine. Joe

I Have HPofficejet 5510.some pages fax while some do not. I get communication error message. Please help

Sounds like some bad copper wire somewhere:

Try replacing the telephone wire between the fax machine and the wall.
If you have dsl, make sure the fax phone wire is plugged into a filter.
Try setting the fax machine to transmitreceive at a slower speed.
This could indicate a problem with your phone wires. Is there static on your phone line?
Maybe give your telephone company a call and have them check the line(s).

Hope this helps!

I cannot get my fax machine to work, I have had this printer allinone for a couple years and it all work great but I cannot get the fax to work now that I need it and the phone company is telling me it is...

Your problem is not clear, all I get is it is a HP, it is a couple of years old and it doesn't work?

Do you have it connected to a good phone line? Just because it is there in the wall doesn't make it good.
Is the fax end of the cable plugged into the LINE port on the machine?
Is the cable good?
Can you phone the machine?
Does it ring?
Does it have a hand set?
Can you call out on it?
If you put paper in the feeder, does it draw it in?
Does it let you dial a number?
Does it try to send?
If it fails, what is the message on the screen?
Run through these steps and if it still doesn't work contact us for the next steps.

Hope this is of some help.

Download fax

Go to and download the drivers from the website for free. Then you should be able to run the program on your computer and it will prompt you on what to do next. Make sure you do not plug printer to computer until it prompts you to. This should work. Please rate my help if this works. Thanks again!!

Turn off the unit and remove the toner cartridge to visually inspect for more paper. Replace cartridge if necessary. Also the problem may be in the fuser. Good luck and God bless.
