Print Unable 71 means Polygon Mirror Failure on the Brother HL-4040, MFC-9840 and MFC-9440.
Pretty safe to say it means the same thing on the MFC-8880.

The Polygon Mirror is part of the Laser Unit, and its rpm isn't within specs.
The Laser Unit must be replaced.

you need to turn it on, Go, . START>>RUN>>services.msc enter. When the services screen comes up, scroll down until you find the "Print Spooler" Enable it, Start it, and set to Automatic, reboot, ya good to go.

That error means the fuser has gone out, could be a dead lamp, or temperature sensors. Chances are you need a new fuser if you have 50,000 or more prints on this machine. www.precisionroller.com will have a new fuser.

Bad news. The laser diode responsible for printing black has up and died. You need a new Laser Unit, part number LR1461001. Brother has released a "Service Update" about this one; the instructions for replacing the laser unit run to nine pages. If you're within the 1-year warranty, it won't cost you, but it won't be printing with it today.

5A: encoder disc or encoder strip or main circuit board or printhead circuit board or power supply defective!

Sorry, cant be fixed by yourself!

Ther is a small viewport (about 1/4" dia) on each end of the cartridge that a photo sensor apparently shines through. The port is not near the bottom, so there's room for plenty of toner below it. Put a small piece of electrical tape over one of them and it will print fine..
Just a thought it worked for soe of my frnds..its worth a try..
Good luck!

5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!
