Ussally drum/toner would fix, will not be fuser, I would suspect Hi voltage board or laser unit, In australia these machines carry a 2 year return to base warranty.
Try reseting the drum counter, this also resets Bias voltage, might be your problem. open front cover with power on and press set, arrow to change drom and select yes.
Otherwise it would be a high voltage board problem, possibility alsoexist that it could be laser unit
Check status page for "71" errors, menu * 2 8 6 4 very very fast, machine will beep "maintence displays" then 77 to print out status page, 99 to return to normal.

I had the same problem and I just fixed it.
It turns out that the toner cartridge I was using was not an authentic brother cartridge. It was an Office Max knockoff.
I replaced the knockoff with an original BROTHER toner cartridge and BAM! Right back in business.
What tricked us for so long was that the knockoff worked for two weeks before it conked out, so while we were looking for the problem, we kept saying to ourselves, "No, it COULDN'T be the toner cartridge. It's practically brand new."
Hope this helps.

I have the same problem. It appeared to happen only after I changed the drum but Brother says it's not the drum but could be the laser or something mechanical. It is totally random, sometimes it's fine for a week and other times it happens a few times a day.
It happens with printing and faxes. Not sure about copies.
Did you ever find a solution?
