My Brother HL-5740 Is jamming after every print jog. It's pulling two sheets through, the first sheet with the print job and the second sheet clear, Its like every job has two sheets. The second sheet always is a blank sheet. If a job have two printed sheets, it will print three sheets and the last one blank - but jamming on the second sheet.

sounds like your printer wants to form it's own three piece band(kidding here).

sounds like you rollers are dirty or have something on one or both of them..like tires on a slippery road, these need to be clean and dry.

I had the same problem with a Brother MFC-8460 and called Brother's support line. The solution that worked for me was to lift the top cover where the sheets of paper go through when you fax. On the right of the black rectangluar piece with grey roller there is a slot in the tray with a black lever inside. The black piece was stuck down inside the slot and had to be popped back out. Once it was out I hit the stop button and it was fixed!!

SOURCE: Brother HL2030 laser printer. Paper jam,

There are several sensor flags along the paper exit route, if
any one of these flags stick or have broken the printer will
take the paper so far then shows jam.

remove the drum unit first then the paper jam, look directly
into the printer to where the drum unit sits and check to see
if one of the flags is sticking up-rite in the centre area.Its spring
loaded so as you push it back, it springs forward again thats ok

Remove base paper tray:
The other flag is at the rear and can be accessed by opening
the rear door and then by opening the inner paper exit ***'y
you can then see the flag on the exit ***'y,this is also spring
loaded. If any of these are out of place/stuck or broken a paper
jam will always occur.
let me know what you find!!
