If the touch screen on your Ingenico iSC 250 payment terminal is not working or is registering input in the wrong areas, you might need to recalibrate it.
- In Ascend, select the Options icon.
- Select Payment Processing > Pinpad Setup.
- In Pinpad setup, select the Calibrate icon.
The Calibrating Device window opens and your Ingenico terminal will scroll through several windows for about a minute. Then, the Ingenico terminal will restart and you'll be all set!
Note: Re-calibrating your Ingenico terminal can fix many problems, including issues where it won't accept a firmware update.
