My brother HL2040 printer shows

try turning it off, diconnect from computer.. Leaving it disconnected,turn it on, when green light indicates it is ready, tap the green go button 5 times real quick.

this should print a self test, if that works as I suspect it may, it is because the document that the computer is trying to print is not the same paper size as set on printer or trying to print to wrong trat ie bypass, ensure paper type is set to plain too.

If a test page tried to print but then came up out of paper, check there is nothing stuck in paper path (rear door?) and if game, give rubber feed roller a clean


Chances are and I;ll lay me bet 10-1 that paper size of document is different than tray setting and placing a sheet of paper in bypass(slot at front) is what your machine is trying to say to you. see how ya go..cheers
