(7) Press the Platen Button to insert the Platen, and check the clearance between the flap of the Clearance
Sensor and the T-shirt. If the Platen height is appropriate, the space is around 2.0 mm, to avoid the fuzzy
fibers on the surface. Adjust the Platen Height by moving Platen Height Adjustment Lever.
<Note>
 Make sure you check the space when the Platen is moving, so that Clearance Sensor works properly.
While the platen stops, it is in upper position.
 When the surface/back of the Clearance Sensor is dirty, it may damage the printing material when
loading. Wipe off the dirt with a soft wet cloth with water. (See "6-1-2. Replacing the Wiper Cleaner and
Cleaning the Caps / Wipers".)
 If the Platen height is too high, the T-shirt, Print Head, or both of them may be damaged when printing.
