The touch screen is not operating correctly.
Calibrate the touch screen. Enter Configuration mode and select Terminal
Settings>Input Devices>Touch Screen>Calibration.
The calibration requires four user screen touches. When the touches do not
converge to a satisfactory calibration, you are asked repeatedly for additional
screen touches; the calibration does not terminate.
A touch screen that does not calibrate is not present or not functioning properly.
Replace the 1000 display module or the 400 to 600 terminal.
The display may not have a touch screen.
Check the catalog number of the unit. Verify that your terminal has a touch
screen by looking at the label on the terminal.
The screen cursor is not visible.
Verify that the cursor is enabled. Enter Configuration mode and select Terminal
Settings>Input Devices>Touch Screen>Cursor.
The touch screen does not accept touch
input.
Attach a USB mouse to check whether the problem is with the touch screen or
the application.
•
If the mouse works, but the touch screen does not, the touch driver or touch
screen is not functioning properly.
•
If the mouse and touch screen are not working, then the problem is with the
application.
Touch input and dragging is inaccurate. The
touch screen is present and working but
requires calibration.
Calibrate the touch screen. Enter Configuration mode and select Terminal
Settings>Input Devices>Touch Screen>Calibration.
