Paper handling6
First, make sure that you are using paper that meets Brother recommended paper specifications. (See About 
paper on page 1.)
ProblemRecommendation
The printer does not feed 
paper.
If there is paper in the paper tray, make sure it is straight. If the paper is curled, 
straighten it before printing. Sometimes it is helpful to remove the paper. Turn the 
stack over and put it back in the paper tray.

Reduce the amount of paper in the paper tray, and then try again.

Make sure that manual feed mode is not chosen in the printer driver.

Clean the paper pick-up roller. See Cleaning the paper pick-up roller 
on page 140.
The printer does not feed paper 
from the manual feed slot.
Make sure that you have chosen the Manual in the Paper Source of the printer 
driver.
The printer does not feed 
envelopes.
The printer can feed envelopes from the manual feed slot. You must set up your 
application to print on the size of envelopes you are using. This is usually done in 
the page setup or document setup menu of your software. (See your application 
manual.)
A paper jam has occurred.
Clear the jammed paper. (See Paper jams and how to clear them on page 147.)
The printer does not print. 
Make sure that the cable is connected to the printer.

Make sure the printer is powered on and that no error messages on the LCD.

Make sure that you have chosen the correct printer driver.
When printing on normal paper, 
it creases.
Change the printer driver setting in Media Type to a thin setting.
The paper slides off the top 
output tray.
Lift up the support flap (1).

Paper jams and how to clear them6
If paper jams inside the printer, the printer will stop. One of the following LCD messages will appear to tell 
you where to find the jammed paper.
 

JamTray1 (1)
Paper jam in the standard paper tray (Tray 1). (See page 148.)

Jam Rear (2)
Paper jam where the paper comes out of the printer. (See page 149.)

Jam Inside (3)
Paper jam inside the printer. (See page 151.)
If the error message still appears on the LCD after you remove the jammed paper, there may be more paper 
jammed somewhere else. Check the printer thoroughly.
Note
Always remove all paper from the paper tray and straighten the stack when you add new paper. This helps 
prevent multiple sheets of paper from feeding through the printer at one time and prevents paper jams.

Jam Tray 1 (Paper jam inside the paper tray)6
 
Jam Tray 1
If a paper jam occurs inside the paper tray, follow these steps:
aPull the paper tray completely out of the printer. 
bUse both hands to slowly pull out the jammed paper. 
Note
Pulling out the jammed paper downward allows you to remove the paper easier.
 
cMake sure that the paper is below the maximum paper mark. While pressing the green paper-guide 
release lever, slide the paper guides to fit the paper size. Make sure that the guides are firmly in the slots.

bOpen the back cover. 
CAUTION 
After you have just used the printer, some internal parts will be extremely hot. Wait at least 10 minutes for 
the printer to cool down before continuing to the next step.
