<Operating Procedure>

screen shown below appears on the LCD.

(3) When the center (the 5th mark) is touched, “OK” is displayed on the LCD if the specified
area is adjusted correctly. The machine returns to the initial state of maintenance mode.
Note:
This adjustment requires a touch pen with a thin tip. A commercially available touch pen
designed for electronic dictionaries or personal digital assistance (PDA) can be used. If one
is not available at hand, order a “Touch pen” from Brother's parts list.
Note:
• Do not use any tools other than a touch pen. In particular, never use a pointed tool
(e.g., screwdriver). Using such a tool will damage the touch panel.
• Do not touch the touch panel with your fingers. The contact area of a finger is too large
to adjust the touch panel precisely.
• If no operation is performed for one minute or the [X] is pressed, the machine returns
to the initial state of maintenance mode.
Note:
If “NG” is still displayed on the LCD even after this operation is repeated two to three
times, check the connection of the touch panel flat cable. If the LCD keeps displaying
“NG” even there is no problem, replace the panel PCB ASSY.
