Autochanger Error Codes Jukebox Micro-Move Error Codes Table B-13 Sequence Tests (For models 40fx, 80ex, 125ex, and 220mx ONLY) No. Test Name Description 43 Mailslot Sensor Test See the description for Test 42. (Interactive if done through the control panel) 44 Cartridge-in-path Displays max/min intensity and ambient (Interactive if done readings for the left and right beams. You must through the control enter a parameter to choose the beam to display panel) (0=left, 1=right). The following is an example of an error message for the right beam and how it is translated: F0 is hexadecimal for 240 E1 is hexadecimal for 225 R means right beam 06 is the maximum ambient reading. 00 is the minimum ambient reading. Intensity L/R Ambient Max Min Max Min 240 225 R 6 0 Press CANCEL to stop. 50 Find Home Sequence 50Find Home SequenceMoves the picker to a known "home" position. This test assumes nothing about the state of the mechanics. The "home" location is the lower left position of the box. The servo system is initialized to the "home" location. It then automatically runs Test 51. 51 Carriage/Picker Runs the portion of the mechanism recalibration Assembly Calibration related to the optical sensors. It measures sensor Test offsets and calculates picker tilt and droop. This test assumes that the mechanics and servo system are functional. B-50 Appendix B
