I recently had this problem - tested fuser and all sensors.
The fix is to reset the memory.
To do this, enter the Maintenance mode. Menu, * 2864
(enter the number quickly)
then type 01 ( zero one ), this will reset all memory including the user settings.
Finally type 99 to exit Maintenance mode.
The printer will restart and the error will be gone. Test out with copy and printer reports
Hoping this fixes your problem

First guess is you have a bit of dirt (often white-out from people scanning corrected paper that's not quite dry) stuck on the fax scan window. This should be described pretty well in your user manual (which you can download online from brother.com).
Its also possible that there is dirt (typically loose toner) on the laser scan window (there's a laser that shines through it to get the image pattern on the drum). That window is often along the bottom of the unit under the drum/cartridge (take the cartridge out and look). The Brother manual I've seen seems to ignore this possibility.
Print streaks DO NOT mean cartridge drum replacement in many cases !! On brother Intellifax or MFC or other laser copier/printer/fax, keep in mind that either the fax/copy scan window OR the laser scan window can get dirty. If the fax scan window is dirty, you see streaks on outgoing faxes and copies (but NOT incoming faxes). If the laser scan window is dirty, you see streaks on all prints (copies, faxes, print-from-computer).
Note also that when transporting/moving some laser copier with the toner cartridge inside, the toner can get out and make a big mess inside (including getting the laser scan window dirty). An air compressor can be usefull to blow it out. And sometimes using alcohol to clean is a BAD idea (maybe incompatible with plastic and rubber parts). A damp rag is probably fine.

With some Brother printers you can try this.
Access the internal maintenance mode by pressing the Menu/Set button, then press * 2 8 6 4 within 2 seconds. This should put you in the maintenance mode menu. Enter 80, and then scroll down with the arrow down (round) key. You'll find an entry listed as purge count. If number is over 6000, enter 2 7 8 3.
This will reset the purge count value. Then the printer will restart, hopefully without the annoying cannot clean message.
Some times this happens because of using cheap compatible ink cartridges if this is the case change the ink cartridges.
Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.
