1.3.12 Adjust touch panel (function code: 61) (Touch panel models only)

<Function>

This function is used to adjust the touch panel.

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.

<Operating Procedure>

(1) Press the [6], and then the [1] key in the initial state of maintenance mode. The

adjustment screen shown below appears on the LCD.

(2) Use a touch pen and touch the center on the mark at the upper left corner of the screen.

The mark disappears when touched, then touch the mark at the lower left. Similarly
touch the mark at the lower right, upper right and center.

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] key is pressed, the machine
returns to the initial state of maintenance mode.

(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:

• If "NG" is still displayed on the LCD even after this operation is repeated two to three
