6-19Phaser 3635MFP GP 12General Procedures and InformationDraft 4GP 12 User Interface Tests DescriptionPurposeTo describe the user interface tests that are available in GP 4 System Administration Tools anddC305.ProcedureRefer to the relevant procedure:• User Interface Button Test• Audio Tone Test• LED Indicator Test• Touch Area Test• Display Pixel Test• Video Memory Test• Reset User Interface• Application Checksum Verification• Touch Screen CalibrationUser Interface Button TestUse this test to verify that the buttons on the user interface are working correctly. After enteringthis test, follow the instructions displayed on the user interface to perform, then exit the test.Audio Tone TestUse this test to verify that the audio tone on the user interface is working correctly. After enter-ing this test, follow the instructions displayed on the user interface to perform, then exit the test.LED Indicator TestUse this test to verify that the LEDs on the user interface is working correctly. After entering thistest, follow the instructions displayed on the user interface to perform, then exit the test. EachLED will flash on for approximately 1 second, then off sequentially in a clockwise direction.Touch Area TestUse this test to verify that the touch screen on the user interface is working correctly. Afterentering this test, follow the instructions displayed on the user interface to perform, then exitthe test.Display Pixel TestUse this test to verify that the liquid crystal display module (LCDM) is working correctly. Afterentering this test, follow the instructions displayed on the user interface to perform, then exitthe test.Video Memory TestUse this test to verify that the SRAM used by the video controller on the user interface is work-ing correctly. After starting this test, each video SRAM location will be validated.Reset User InterfaceThis procedure will reset the user interface.Application Checksum VerificationThis procedure will check the user interface application software checksum and any softwarein the extended memory.Touch Screen CalibrationUse this test to re-calibrate the touch screen. After entering this test, follow the instructions dis-played on the user interface to perform, then exit the test.
