"Unable to Print 6F"
The message "Unable to Print 6F" will appear on the display for one of the following reasons:
i. A foreign object, such as a paper clip or ripped piece of paper, is stuck in the machine;
ii. Mechanical malfunction.
To attempt to clear the error, continue to step 1.
1. Using both hands, use the finger holds on each side of the machine to life the scanner cover into the open position.
- Do you see the scanner cover support arm located on the left side of the machine?
- If yes, go to step 2.
- If no, verify you have opened the scanner cover (as in the image above). If the document cover was opened, you won't see the scanner cover support arm. Close the document cover and go back to step 1 to open the scanner cover.
2. Carefully check the left (2) and right (3) hand corners and the center inside the machine and remove any paper scraps that may be jammed.
3. Using your hand, move the print head from left to right, checking carefully for any paper scraps stuck under the print head. Remove any if found.
If the print head is in the right-hand corner, press and hold down the for at least 5 seconds until the print head moves to the middle. This will allow you to check the right corner inside the machine for any paper scraps.
4. Leave the scanner cover open and turn the machine around so you are looking at the back of the machine.
5. Open the Jam Clear Cover (1) on the back of the machine.

6. Check inside for any foreign objects or jammed paper. Remove it found.
7. Close the Jam Clear Cover, then turn the machine back around to the front.
8. Lift the flat-bed scanner cover to release the lock (1), then gently push the scanner cover support down (2) and close the scanner cover (3) using both hands.
- If "Unable to Print 6F" still on the display, go to step 10.
- If "Unable to Print 6F" has cleared, go to step 11.
10. Unplug the machine from the power outlet for approximately one-minute, then plug it back in.
- If "Unable to Print 6F" still on the display, go to step 12.
- If "Unable to Print 6F" has cleared, go to step 11.
11. Print a Print Quality Check Sheet (PQCS).
a. Press on the Touchscreen.
b. Press Test Print.
c. Press Print Quality.
d. Press OK. A PQCS will print.
- If the PQCS print successfully, your machine is working properly. The issue has been resolved.
- If the PQCS doesn't print because "Unable to Print 6F" reappears and you have not cycled the power, go back to step 10.
- If the PQCS doesn't print because "Unable to Print 6F" reappears and you have cycled the power, continue to step 12.
12. Your machine will require service. Any faxes received while the error message is on the display will automatically go into the machine's memory due to the product's inability to print. If there are faxes in memory, you can transfer them to another fax machine so they are not lost.
- If you don't want to transfer faxes, go to Warranty and Service Options.
- If you want to confirm and transfer received faxes in memory, go to step 13.
13. Transferring stored faxes to another machine.
To transfer data from your fax machine to another fax machine, you must have already programmed the Station ID in your machine prior to getting the "Unable to Print 6F" error message. If you did not already have your Station ID programmed into the machine before getting the error, you will not be able to transfer faxes in memory. Continue to Warranty and Service Options.
a. Press to temporarily interrupt the error message.
b. Press on the Touchscreen.
c. Press All Settings.
d. Press ? or ? to display Service. Press Service.
e. Press Data Transfer.
f. Press Fax Transfer.

please describe the noise? Burning smell like plastic?
It's a laser printer, so it's possible that the fuser is an issue. Is there a paper jam in the printer under the fuser?

Brother MFC-8440... | Answered on Feb 06, 2015


Your fuser unit is faulty, could be due to the thermistor in it.

Check setting. Printer and Xerox machines are provided with button or software control for controlling blackness of print.

Brother MFC-8440... | Answered on Oct 04, 2014


Nothing to do, just shut off the printer and wait for 5 min. Then remove the tray and adjust the tray according to paper size and then try to print.

I'm sure I did answer this one. Please don't put the same question here twice or even more. This is not google where you could have a response within .03 seconds and then you can't do anything with the one million hits.

please check the fuser unit side

Brother MFC-8440... | Answered on May 10, 2014


this could be either the thermal fuse on the machine or the power suply. it means that the fuser on the machine is not heating up. this error would need servicing on the machine unfortunatly
