A1.01A4: Failed to pick from Tray 4, and then recovered
Initial Steps
1. Look for intermittent operation of components.
2. Check the condition of the paper in the tray.
3. Check the pick rollers and idler rollers for wear.
4. Verify that the Tray 4 Exit sensor (SN55) actuator moves freely.
5. Check for similar warnings for other paper trays.
HINWEIS: Each paper tray has a pick head calibration pin located at the rear of the tray. Swapping trays can create pick problems.
Return trays to their original positions after swapping for any testing.
Test the Tray 4 Exit sensor (SN55)

2. Manually move the plastic fingers to toggle SN55. If the fingers do not return to the extended position, check the spring on the end of
the plastic shaft.
HINWEIS: Each paper tray has two plastic fingers on a plastic shaft.
TIPP: Click Subsystems, click Input Trays, and then click Trays 2, 3, 4.
