1.4.20 Adjustment of touch panel (Function code 61)
<Function>
This function adjusts the detection area on the touch panel.
Note:
The adjustment procedure requires a stylus with a thin tip. A commercially available stylus
designed for electronic dictionaries or personal digital assistance (PDA) can be used. If you
do not have it on hand, order the "STYLUS" from the Brother's parts list.
<Operating procedure>
(1) Press the 6 and 1 keys in this order in the initial state of the maintenance mode.
The adjustment screens shown below appear on the LCD.
(2) Touch the center of the symbol on the top left of the screen with a stylus. The symbol
disappears upon touching it. Then touch the symbol on the bottom left. In the same way,
touch the symbols on bottom right, top right, and center in this order.
Note:
- Do not use tools other than a pen designed for touch panels. Especially, never use a
pointed one, e.g., a screwdriver. Using such a tool damages the touch panel.
- When performing this adjustment, do not touch the panel with your fingers.
Doing so deteriorates detection accuracy and correct adjustment cannot be obtained.
- If no operation is performed for one minute or the Cancel key is pressed, the
machine returns to the initial state of the maintenance mode.
(3) When you press the symbol at the center (the 5th symbol), "OK" appears if the specified
area is correctly adjusted. Then, the machine returns to the initial state of the
maintenance mode.
Note:
If "NG" appears on the LCD and "NG" still reappears when repeating this adjustment
twice or three times, check the touch panel harness for connection failure. If "NG"
appears in spite of the proper connection of the harness, replace the LCD unit.
