4-5. Placing the T-shirt on the Platen 
 
 CAUTION 
 Ensure there is adequate space left for safe working. The Platen moves forward while operating.   
 Do not handle the platen while printing. If your hand gets caught between the platen or the T-shirt tray and the 
covers, it may be injured. 
 Do not move the Platen by hand. 
The Printer may be mechanically and electrically damaged. 
 
To get the optimum quality print result, you need to adjust  the Platen height depending on the thickness of the T-shirt. 
  
z   The clearance between the Clearance Sensor and the surface  of the Print Heads should be app. 2 mm. If the clearance is 
wider, the ink mist will spread inside the printer and the printing material, and may damage the sensors inside. If you print 
with wider clearance (more than 2 mm) then check the inside of the printer and keep it clean. Replace the Maintenance 
Parts by referring to 6-1. Replacing Consumables and clean by 6-1-6. Cleaning the inside of the printer and restart and 
6-1-7. Cleaning the Encoder Strip.     
z   If Platen height is too low, the result may be poor quality (e.g. a straight line becomes  double). Adjust it properly by test 
moving the platen in with Platen Button on the Control Panel.  When you have to lower the Platen to avoid any material 
which is thicker i.e. hems the hems, use Uni-Directional pr int (see 7-2-4. Changing the Print Direction). You can set a 
print data as Uni-Directional by the Printer Driver. See  4-3-14. Setting Print Direction as Uni-Directional.   
z   The Platen height can be lower by 13 mm by replacing the Bu sh Platen Shaft with Platen Height Adjustment Lever 
assembled and the Platen Positioning Plate to Platen Lowering  Set (option). See 4-4-3. Lowering the Platen height.   
(1)  If the Platen is not ejected, press the Platen Button to eject it. 
(2)  Loose the Platen Fix Lever and adjust the Pl aten Height to A position (leftmost) for T-shirt. Set it to the C position  when 
you print on a sweater or a towel. If t he Platen height is too low, the print quali ty turns worse. Keep the clearance between 
the Clearance Sensor and the surface of  the Print Heads should be app. 2 mm. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Do not use force when you adjust the levers.   
 
(3)  Tighten the Platen Fixing Lever securely.

(4)  Place the T-shirt, with its print side  on the top of Platen and the other side underneath the Platen, as shown below. The Pretreatment must be applied first when you print on dark-color ed T-shirts with White ink. (See 4-6-1. Applying the 
Pretreatment.) 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
z   Pay attention to the hems; neck, arm holes, tags, and the bottom. 
The side edges may raise and hit the Print Head during printing operation. It is important to ensure the t shirt surface 
is flat and smooth.   
z   To align a T-shirt easily, you can print a grid on the Platen Sheet. It is in [ All Program ] > [ Brother GT-3 Tools ] > 
[ Useful Tools ]. Grid14x16.ar3 is for the standard Pl aten 14x16. (See 3-3-7. Opening the Useful Tools.) 
  
(5)    Smooth the surface to remove wrinkles and threads with your hands. Move your hands smoothly and softly from the  center to the edges, to fix the T- shirt and the Platen Sheet together. 
  z   If the surface of T-shirt is not smooth enough, Clearance Sensor may be activated 
z   If you stretch the T-shirt by force , the ink may move and/ or shrink the fibers while printing and the position of white 
ink and colors may be shifted and you will see white lines  around the color print. Do not pull, especially thinner 
materials in setting on the Platen.   
z   When placing a thick fabric such as a sweats hirt, keep its surface as flat as possible. 
(6)    Keep the sleeves and overflows on t he T-shirt Tray to avoid jamming.
