1.4.18 Adjustment of touch panel (Function code 61) (Touch panel model only)

<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 buttons in this order in the initial state of the maintenance mode.
The adjustment screens shown below appear on the LCD.
(2) Touch the symbols on the touch panel with a stylus in the order of top-left, bottom-left,
bottom-right, top-right, and the center. After a symbol touched disappears, touch the next
one.
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.
- Do not touch the touch panel with fingers. The contact area of a finger is too large to
adjust the touch panel precisely.
- If the Stop/Exit button is pressed, the machine returns to the initial stage of the
maintenance mode.
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 in
approximately 3 seconds.
Note:
If the way to press the symbol is wrong, or if a wrong place is pressed, "ERROR" appears
on the LCD, and the machine returns to the screen in step (2) when the Start/Black button
or Start/Color button is pressed. Be sure to press the symbols from the upper left in the
order shown above.
In the case of "NG", repeat this operation 2 to 3 times. If "NG" remains displayed even after
the operation is repeated, check if there is harness connection failure in the touch panel,
disconnection, short-circuit, or entry of foreign objects in the touch panel frame. Although any
of these problems is not observed, if "NG" is displayed, replace the touch panel ASSY.
