1.3.18 Adjust touch panel (function code: 61)
<Function>
This function is used to adjust the detection area on the touch panel.
<Operation Procedure>
(1) Press the [6] and [1] buttons in this order in the initial state of maintenance mode. The
adjustment screen shown below appears on the LDC.
(2) Use a touch panel stylus and touch the center on the mark at the upper left corner of the
screen. The mark disappears when touched. Similarly touch the mark at the lower left,
lower right, upper right and center.

(3) When the center (5th mark) is touched, "OK" is displayed on the LCD if the specified
area is adjusted correctly. Then, the machine returns to the initial state of maintenance
mode.
Note:
• This adjustment requires a touch panel stylus with a thin tip. A commercially available
stylus designed for electronic dictionaries or personal digital assistance (PDA) can be
used. If one is not available at hand, order a "STYLUS" from Brother's parts list.
Note:
• Do not use any tools other than a touch panel stylus. 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 [Stop/Exit] button is pressed, the
machine returns to the initial state of maintenance mode.
Note:
• If the mark is touched wrongly or a wrong position is touched, "NG" is displayed on the
LCD. When the [Start] button is pressed while "NG" is displayed, the LCD returns to the
display in step (2). Touch from the upper left mark in order again.
• If "NG" is still displayed even after this operation is repeated two to three times, check
the connection of the touch panel harness. When the connection is correct, replace the
LCD unit.
