To verify the result, do the following:
1 Load the ADF with a document containing light and dark content.
2 Print a two-sided copy of the document.
Notes:
• If the back side of the copy has vertical streaks, then clean the scanner glass and backing material,
and then print another copy.
• If the streaks still appear, then repeat the cleaning and verification procedure or replace the ADF.

A dialog listing the sensor tests appears.
3 Find, and then manually toggle the sensor.
Notes:
• The sensor status on the screen toggles between 1 and 0 when the sensor is properly working.
• If a sensor test fails, the test failure may not indicate a failed sensor. Further troubleshooting may be
required. Check the boards and cables for possible issues.

1 Enter the Diagnostics menu, and then navigate to:
Additional input tray diagnostics > Motor tests
2 Select a motor, and then touch Start.
Notes:
• If the motor is activated, then it is properly working.
• Some motors require automatic deactivation in order to avoid secondary issues such as possible
damage and contamination.
• Some tests require a special action to activate a motor such as removing a major component.
• If the motor fails, the test failure may not indicate a failed motor. Further troubleshooting may be
required. Check the boards and cables for possible issues.
