If this only happens when you are copying.
1. Your scanner glass is dirty. Open the lid, use windex to clean the
flatbed. Look on the left side. You should see a strip of glass, with
the scanner sitting under it. This strip is used when the document feed
is being used. Make sure it is clean. Most common problem is getting a
little whiteout or the sticky residue from scotch tape on this glass,
which causes lines down your copies.
Clean it with alcohol which will dissolve the sticky stuff and the whiteout.
If this does not solve the problem, the CCD scanner in your machine might be going bad.

The solution, and it took me a long time to find the simple solution, is to right click on your printer, click properties, click the ports tab and click on your Brother printer and click on configure port (or you can delete the existing one and then add another one). What you want to do is update the IP Address. The problem is that the printer does not have a static IP address, it is dynamic. If you want to confirm that, go to your printer and press the reports button and print out the network configuration report. Your IP address will show on that. It's really the last digit in the IP address that changes. This will absolutely solve your problem. Good Luck!

Do you mean "unable to clean"?If it this follow this instruction.
Unplug the printer from power cord.Press and hold the "menu" button, then plug the device.You'll see on the LCD screen a "machine error" code.If this code is 40,41 or 4F the print head is defective.If the error is 50 or 51 there is error in Purge unit and printer require service.If the error is 46 the waste ink tank is full.Follow this:Enter 80, then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If numberis over 6000, enter 2 7 8 3.This will reset the purge count value. Then restart the printer, hopefully without the annoying cannot clean message.

Often means something is blocking the printhead from traveling all the way left & right. Look carefully in there, especially under the ends, for a scrap. It may be black with ink and hard to spot, but if you see it, a minute with some tweezers may fix everything.
Sometimes the timing strip gets knocked out of its sensor, so the machine can't detect whether it's moving when it turns on the motors, so it locks up with that error. Getting to that is a bit trickier. Open the top and pry out a couple of skinny plastic covers that hide cables. One of those covers acts to lock in the lever that holds the top section up; once you've removed the cover, you can unsnap the lever from the bottom end, allowing you to stand the top (scanner) section straight up. Take a good look at the cables & how they're laid. The flat white one is especially delicate, and must not be reinserted crooked. Unplug those cables and pull them out of the way so you can remove the top cover they're laid in. There's also a ground wire to unscrew.
The top is held on with what - six or seven screws? Keep track of which goes where. I think the front edge is caught by a plastic hook, also. Free it by prying with a small screwdriver, and lift off the top cover.
The whole printer mechanism is now exposed. You can see the 1/4-inch (6mm) wide strip of film that's stretched tight across the entire width of the printer area. The gray in that strip is hundreds of fine vertical lines. A sensor in the printer head carrier shines through those lines and counts them to keep track of where it is at all times. If you find the film strip laying flat across the top of the printhead, just lift it carefully and lower it into its slot in the sensor. It should be vertical and straight. Don't get ink or fingerprints on that strip; it can be cleaned - very gently - with a damp cloth.
Put the cover back on, install those cables, the lever that holds the scanner up, and the little covers, and try it out.
If it's not a paper scrap or that timing strip, it's probably too expensive to mess with, but check with the closest service center listed on Brother's website. If none appear to be close enough, don't be shy about calling one of the closest ones and asking if they have another branch that's not listed on Brother.
